Practical Application Cases for FESTO SDE1-D10-G2-W18-L-P2-M12 Pressure Sensor

Sensor features: 0-10 bar relative pressure, dual-PNP switching output, M12-4 pin, G1/8 internal thread, montaggio a parete, backlit LCD, teach-in configuration. Mainly used for compressed-air monitoring. Dual-PNP channels support upperand lower-limit dual-threshold alarm: one channel for low-pressure alarm, the other for high-pressure alarm; or one for normal signal and one for fault alarm.

Nota: SDE1 is discontinued. New projects adopt SDE5-D10-O1-Q4-2P-M12 as replacement.

Caso1: Main-air-supply Monitoring for Automation Equipment (assembly machines, transfer machines)

Condizioni di lavoro

Wall-mounted SDE1-D10-G2-W18-L-P2-M12 installed downstream of the main FRL unit to monitor equipment air supply. Medio: filtered compressed air, nominal working pressure 5-7 bar.

Impostazione dei parametri

Out1(PNP1): Lower-limit threshold 4.5 bar. Output ON below 4.5 bar for low-air-pressure alarm.

Out2(PNP2): Upper-limit threshold 7.5 bar. Output ON above 7.5 bar for high-air-pressure alarm.

Logica di controllo

PLC reads two switching signals. Allarme & equipment inhibit when pressure is too low or too high. Equipment enable only if pressure stays within 4.5-7.5 bar.

Valore

Avoid cylinder jamming / weak actuation caused by insufficient pressure; prevent damage to cylinders and valve islands by overpressure. Local backlit LCD for direct on-site pressure reading without upper-host communication.

Compatibilità

W18 integrated wall-mount bracket fastens directly to cabinet sheet metal near valve islands. Vibration-resistant M12 connector for workshop environments. IP65 resists cutting-fluid splashes.

Caso2: Clamping-cylinder Pressure Monitoring in Packaging Machinery (case packers, sigillanti di casse, heat-sealing machines)

Condizioni di lavoro

Clamping mechanism of packaging machine. Cylinder target pressure 4-6 bar. Insufficient pressure fails to clamp cartons; excessive pressure damages products. Sensor fitted downstream of clamping-cylinder pressure-regulator.

Impostazione dei parametri

Out1: Window lower limit 3.8 bar

Out2: Window upper limit 6.2 bar

Adopt window-comparator mode. Alarm trigger when pressure goes outside 3.8-6.2 bar.

Processo

Clamping action is permitted only after sensor confirms valid pressure. Emergency stop and alarm upon pressure anomaly to avoid batch-product damage.

This unit provides only switch outputs, no analog signal. Suitable for pass/fail judgment without high-precision pressure acquisition.

Caso3: Fixture Tooling for Automotive-component Assembly (welding fixtures, press-fit tooling)

Condizioni di lavoro

Pneumatic press-fit tooling. Press-cylinder set-point ~6 bar. Low pressure causes incomplete press-fit; high pressure causes workpiece damage. Sensor mounted at regulator output of fixture.

Configurazione dei parametri

Out1: <5.2 bar → low-pressure alarm

Out2: >6.8 bar → over-pressure alarm

Logica

PLC receives sensor signals. Press-fit motion blocked and audible-visual alarm activated upon pressure fault. Operators read real-time pressure locally on LCD to adjust regulator without external pressure gauge.

On-site Features

Vibration-resistant M12 connection for tooling environment. Teach-in keys for quick on-site threshold adjustment. Password lock prevents unintended operator modification.

Caso4: Back-pressure Detection for Material-handling Suction Cups

Avviso: Measuring range 0-10 bar, cannot measure vacuum / negative pressure. Only for positive-pressure back-pressure detection, mostly for blow-type workpiece detection.

Condizioni di lavoro

Blow-type detection: Nozzle blows air toward workpiece. Pressure rises when workpiece blocks nozzle; pressure drops when no workpiece present.

Impostazione dei parametri

Out1: Output ON when pressure＞2 bar → workpiece detected

Out2: Canale di riserva, configurable for over-pressure protection

Applicazione

Alternative to vacuum pressure switches for positive-pressure workpiece presence detection. Widely used in electronic-part sorting and injection-molded-part picking.

Caso5: Branch-line Pressure Monitoring for Air-treatment Units (multi-station equipment)

Condizioni di lavoro

Independent pneumatic branches for transfer, bloccaggio, lifting functions. One SDE1 sensor fitted on each branch after regulator.

Logica

Dual-PNP outputs: one for pressure-loss alarm, one for over-pressure alarm. M12-wired to PLC digital-input modules for fast fault-location of faulty air branches and reduced troubleshooting time.

Caso6: Auxiliary Equipment for Injection-molding Machines (robot, material chutes, gate-cutting equipment)

Condizioni di lavoro

Pneumatic-circuit monitoring for injection-molding robots. Nominal working pressure of robot cylinders and grippers: 5-6 bar.

Note sull'utilizzo

IP65 against workshop dust and oil contamination. Backlit LCD guarantees readability under poor workshop lighting. Dual-switch outputs realize both low-pressure and over-pressure protection.

Limitazioni dell'applicazione & Practical Pitfalls

1. Only measures positive relative pressure 0-10 bar; vacuum measurement not supported. Select SDE1-V1 (-1~0 bar) variant for vacuum applications.
2. Dual-PNP switch outputs only, no analog output. Choose -PI /-PU suffix for 4-20 mA / 0-10 V analog signal.
3. Medium restricted to filtered compressed air. Not for water or hydraulic oil. Condensate in compressed air will damage sensor.
4. W18 stands for wall-mount installation, not DIN-rail mounting. Select -H18 suffix for DIN-rail mounting.
5. Discontinued product; only stock / used spare parts available. Replacement SDE5-D10-O1-Q4-2P-M12 with largely compatible installation and functions.

B (Giù): OutB Channel 2, value decrement

RUN mode: Power-on default, displays real-time pressure; long-press EDIT for 3 s to return to RUN at any time.

Four operation modes:

1. CORRERE: Operazione, real-time-pressure display
2. SHOW: Parameter review (read-only)
3. EDIT: Parameter editing (threshold, modalità, unità, password)
4. TEACH: Teach-in, capture current pressure as switch-point

P2 model: OutA = Channel 1; OutB = Channel 2, dual-PNP output. Impostazioni di fabbrica: threshold comparator, NO normally-open, hysteresis HY=0.2 bar (2%FS), unit bar, password lock disabled.

1. Pre-configuration Preparation
2. Supply DC24 V, connect air supply. Sensor enters RUN mode and shows real-time pressure.
3. Flashing `Lock` on display: password lock activated. Password input required before modification. Direct-access to EDIT if unlocked.
4. M12 connector tightening torque: 0.5 Nm. Do not over-tighten G1/8 thread.
5. Enter EDIT Edit Mode
6. Under RUN mode, short-press EDIT. Display flashes `OutA` (Channel 1 selected).
7. Press B to switch to `OutB` for Channel 2 setup.
8. Short-press EDIT again to enter parameter editing for selected channel.
9. Short-press EDIT to confirm each item and jump to next parameter.
10. Long-press EDIT for 3 seconds to save all parameters and return to RUN.

Each channel can be independently configured: modalità operativa, switch-point, hysteresis HY, NO/NC normally-open / normally-closed.

Two Output Operation Modes

1. Threshold comparator _|¯ (single set-point SP)

NO: Output PNP ON when pressure＞SP; OFF when pressure＜SP-HY.

NC: Output PNP ON when pressure＜SP-HY; OFF when pressure＞SP.

2. Window comparator _|¯|_ (SPmin lower limit, SPmax upper limit)

NO: Output ON when pressure is between SPmin～SPmax; OFF outside range.

NC: Output ON when pressure is outside SPmin～SPmax; OFF inside range.

Typical usage:

Upper-lower-limit alarm: OutA for low-pressure alarm (threshold comparator NO); OutB for high-pressure alarm (threshold comparator NO).

Qualified-range detection: Single-channel window comparator, output ON when pressure stays within valid range.

3. Method A: Manual Numeric Entry (Raccomandato)

Sample requirement:

OutA (Channel 1): Alarm below 4.5 bar; threshold comparator, NO, HY=0.3 bar

OutB (Channel 2): Alarm above 7.5 bar; threshold comparator, NO, HY=0.3 bar

Configure OutA (Low-pressure Alarm)

1. RUN → short-press EDIT, flashing `OutA`, press EDIT to enter.
2. Select mode `_|¯` threshold comparator, confirm with EDIT.
3. Set SP switch-point to 4.5 bar, confirm with EDIT.
4. Set HY hysteresis to 0.3 bar, confirm with EDIT.
5. Select NO normally-open, confirm with EDIT.

Configure OutB (High-pressure Alarm)

1. Return to EDIT top menu, press B to switch to `OutB`, press EDIT to enter.
2. Select mode `_|¯` threshold comparator, confirm with EDIT.
3. Set SP switch-point to 7.5 bar, confirm with EDIT.
4. Set HY hysteresis to 0.3 bar, confirm with EDIT.
5. Select NO normally-open, confirm with EDIT.
6. Long-press EDIT for 3 s to return to RUN. Parameters take effect.

Window-mode procedure: Selezionare , then configure SPmin, SPmax, HY, NO/NC sequentially.

4. Method B: TEACH-IN Teach-in Calibration (Fast On-site Setup)

Capture actual pipeline pressure as switch-point without manual numeric input.

1. RUN mode, adjust air-supply pressure to desired switch-point TP1.
2. Simultaneously press【A + EDIT】. Current pressure is saved as TP1 for selected channel.
3. Adjust air-supply pressure to second target TP2, press【A + EDIT】again to save TP2.

Threshold-comparator mode: SP is calculated as mid-value between TP1 and TP2.

Window-comparator mode: TP1 = SPmin, TP2 = SPmax.

4. Long-press EDIT to return to RUN.

For OutB teach-in: Use【B + EDIT】key combination.

5. Unit Setting & Password Lock
6. Short-press EDIT under RUN mode. Scroll with A/B keys to find `Lock`.
7. Press EDIT to enter sub-menu:

Unit selection: sbarra / kPa / psi; bar preferred for industrial applications.

Password lock: 0 = lock off; 1-9 = lock enabled. Password required before entering EDIT.

When password lock is enabled, `Lock` flashes upon entering EDIT. Input password with A/B keys and confirm with EDIT to unlock.

Forgotten password: Ripristina le impostazioni di fabbrica.

6. SHOW Mode: Parameter Review (Read-only)

Under RUN mode:

Press A: Scroll through OutA parameters: modalità, SP, HY, NA/NC

Press B: Scroll through OutB parameters: modalità, SP, HY, NA/NC

Press A+B simultaneously: View max/ min-pressure values; long-press A+B for 2 s to clear peak-value records.

7. Restore Factory Settings

Spegnimento; hold A+B pressed, power on, keep holding and press EDIT. Display flashes for several seconds. All custom parameters reset and password cleared.

⚠️ All user-configured parameters will be lost. Operate with caution.

8. Common Commissioning Troubleshooting
9. Nessun segnale in uscita

Verify NO/NC configuration; check relation between SP threshold and actual pressure; PNP output load ≤150 mA; confirm 24 V supply.

2. Frequent output chattering: Increase hysteresis HY, per esempio. from 0.2 bar to 0.3-0.5 bar. Mandatory for fluctuating air supply.
3. Parameter modification forbidden: `Lock` flashing. Unlock by password input or restore factory settings.
4. Inverted alarm logic: Toggle NO (normally-open) ↔ NC (normally-closed).
5. Reference Engineering Configuration (Air-supply Monitoring)

Logica PLC: OutA = 0 → low-pressure alarm; OutB = 1 → over-pressure alarm.
