5. Варианты замены (Critical Section)

No direct pin-to-pin upgraded model available with original F43 flat housing. Two selection options:

Measuring range: 100…2000 mm

Выходы: 4–20mA analogue + 2 PNP switching outputs + RS232

Разница: Транзисторный выход, no relay contacts; Cylindrical housing with different mounting dimensions

If passive relay contacts are mandatory on site, select third-party ultrasonic sensor paired with external relay.

Вариант 2: Maintain Relay Output

Only used / refurbished stock available for legacy series. Для новых проектов:

UC2000-L2-IUR2-V15 + auxiliary miniature relay for contact conversion.

6. Выбор & Руководство по эксплуатации / Избежание ловушек
7. Blind Zone Limitation: Reliable measurement impossible within 100 мм; Do not select for close-range applications.
8. Acoustic Cone Interference: Activate sensor synchronisation function when multiple sensors are installed side-by-side to prevent mutual ultrasonic interference.
9. Medium Limitation: Soft foam, fluffy fabrics produce weak echo and lead to unstable detection.
10. Relay Service Life: Electrical service life limited to 3×10⁵ switching cycles. Not suitable for high-frequency switching applications. Transistor output models are recommended for frequent operation.
11. Programming Requirement: Adjustment of switching points, measuring range and hysteresis requires UC-PROG1-USB programming cable. No external teach-in button available.

Пепперл+Фукс UC2000-F43-2KIR2-V17 Practical Application Cases

Core Feature Recap (All cases based on unique strengths of this model)

Flat F43 rectangular housing, measuring range 100～2000 mm;

2 SPDT passive relay contacts + 4…20mA analogue output + RS232 programmable interface;

Highlight: Single sensor integrates dual limit switching + continuous distance transmission. Passive relay contacts can directly drive contactors and audible/visual alarms. Flat housing fits confined mounting spaces; IP65 rated with built-in temperature compensation.

Важное напоминание: This sensor is discontinued by the manufacturer. Alternatives are recommended for new projects. The below cases are proven historical applications.

Cse 1 | Wastewater Treatment: Level Monitoring & Pump Control for Open Settling Tank

Working Conditions

Open regulating tank in small wastewater treatment plant with surface foam and high humidity. Требования:

① Continuous level signal transmitted to PLC via 4–20mA;

② Low-level pump start, high-level pump stop (two relays directly control contactors to reduce PLC point consumption);

③ Limited installation space above tank guardrail, cylindrical sensors cannot be fitted.

Implementation Scheme

Sensor installed horizontally with downward tilt above the tank, avoiding severe foam zones.

Реле 1: High level limit (1.6 м) → Trigger to stop drainage pump

Реле 2: Low level limit (0.4 м) → Trigger to activate water inlet

4–20mA signal sent to central control for real-time liquid level display

RS232 used on-site to calibrate measuring range and hysteresis, suppressing frequent fluctuation caused by water ripples.

Reason for Model Selection

Flat F43 housing compatible with narrow mounting brackets; Passive relays drive contactors directly without additional auxiliary relays. Ultrasonic measurement immune to water colour and mild foam.

Risk Notes

Thick foam absorbs ultrasound; proper mounting tilt required. Blind zone of 100 mm prevents low-level alarm setup near tank bottom.

Случай 2 | Plastic Extrusion Industry: Residual Roll Diameter Monitoring for Film / Nonwoven Web

Working Conditions

Continuous unwinding of raw material rolls on cast film production line. Control system requirements:

1. Real-time roll outer diameter measured; 4–20mA signal sent to tension controller for automatic unwinding torque regulation;
2. Dual limit: Low material pre-warning + complete roll depletion safety shutdown.

Implementation Scheme

Sensor mounted laterally on machine frame, aligned horizontally with roll outer surface; 0.1~2m measuring range matches maximum roll diameter.

Реле 1: Minimum roll diameter reached (pre-warning) → Audible & visual alarm for material preparation

Реле 2: Roll diameter hits minimum limit → Full production line safety shutdown

Continuous 4–20mA analogue distance output for roll diameter conversion and closed-loop tension control.

Selection Advantage Comparison

Conventional transistor-output sensors rely on PLC logic for dual alarm functions. Built-in relays enable direct wiring to alarm circuits for legacy retrofit projects without modifying PLC programs.

Operation Tip

Surface wrinkles and web vibration cause signal fluctuation; configure sufficient measurement hysteresis via software.

Случай 3 | Logistics Conveyor Line: Pallet Height Detection & Dual Position Limit

Working Conditions

Roller conveyor for automated warehouse transporting wooden / plastic pallets. Photoelectric sensors prone to false triggering caused by dust and pallet gaps. Требования:

① Confirm pallet arrival (near-point switch);

② Overheight pallet detection to prevent jamming in vertical lift;

③ Real-time pallet height data uploaded to WMS for cargo dimension verification.

Implementation Scheme

Sensor side-mounted above conveyor channel:

Реле 1: Pallet arrival confirmation signal

Реле 2: Pallet overheight alarm, trigger conveyor emergency stop

4–20mA output of measured pallet height sent to upper system for cargo dimension validation.

Основная ценность

Slim flat housing embedded into narrow side space of conveyor. Ultrasonic detection unaffected by pallet holes and dust; passive relay contacts compatible with legacy safety circuits.

Случай 4 | Chemical Raw Material Hopper: Granular Level Monitoring (Plastic Pellets, Calcium Carbonate)

Working Conditions

Open-top raw material hopper for small extruders. Heavy dust environment unsuitable for capacitive level switches. Требования:

Low-level pre-warning, high-level full hopper shutdown, plus continuous level monitoring.

Implementation Scheme

UC2000-F43 installed laterally at hopper top:

Реле 1: High material level → Stop feeding conveyor motor

Реле 2: Low material level → Start raw material feeding conveyor

4–20mA signal transmitted to central control for daily raw material consumption tracking.

Меры предосторожности

Severe dust clouds attenuate ultrasonic echo; avoid vertical installation facing falling material stream.

Случай 5 | Строительная техника / AGV: Anti-collision Distance Warning System

Working Conditions

Indoor factory Automated Guided Vehicle (AGV). Dual-stage collision protection required:

1. Long-distance pre-warning (speed reduction); 2. Short-distance emergency stop; Continuous distance signal sent to on-board controller.

Implementation Scheme

Flat-mounted F43 sensor on AGV outer body (cylindrical sensors protrude and risk collision damage). Measuring range 100~2000 mm:

Реле 1: 1.2 m detection distance → Vehicle speed reduction

Реле 2: 0.5 m danger distance → Emergency stop

4–20mA real-time distance signal for obstacle distance display on vehicle HMI.

Преимущество

Flat housing resists scratches from cargo. Independent safety relay circuit enables emergency stop even if main controller fails.

Случай 6 | Упаковочное оборудование: Stacked Carton Height Monitoring

Working Conditions

Palletising station for carton stacking. Verify stack height compliance and implement overheight protection.

Реле 1: Stack height reaches target → Robot executes transfer operation

Реле 2: Overheight stack → Equipment lock and alarm

Continuous 4–20mA height data for production data acquisition.

Suitable for rigid flat-surface targets such as cartons and turnover boxes.

Краткое содержание: Ideal Application Characteristics for This Model (Selection Checklist)

✅ Preferred Application Scenarios

1. Confined installation space requiring flat rectangular housing; cylindrical ultrasonic sensors cannot be fitted
2. Retrofit projects with existing control cabinets using passive contact signals; no intention to expand PLC I/O points
3. Processes requiring dual limit switches + continuous analogue transmission integrated within one sensor
4. Direct drive of 220 VAC audible/visual alarms or contactors (passive relay contacts)
5. Environment with wide temperature fluctuation, пыль и влага (built-in temperature compensation, IP65)

❌ Unsuitable Scenarios

1. Applications with millions of frequent switching cycles (limited mechanical relay life; transistor-output sensors preferred)
2. Targets made of thick / soft foam (ultrasound absorption leads to poor detection)
3. Measurement distance below 100 мм (inherent blind zone)
