📌 Core Technical Specifications

🔌 Wiring Definition (3-الكابل الأساسي)

بني: DC+ (Positive power)

أزرق: العاصمة(Negative power)

أسود: 4~20mA signal output → connect to PLC analogue AI current input channel

Working principle: The closer the metal target is to the sensor, the higher the output current (rising from 4mA to 20mA).

15 mm distance = 4 أماه; 1.5 mm distance = 20 أماه.

Used for continuous displacement feedback and closed-loop control, not just discrete on/off switching.

📎 Typical Applications

1. Continuous position closed-loop feedback for hydraulic cylinders / pneumatic actuators (hydraulic presses, tooling clamps, lifting cylinders)
2. Workpiece thickness & gap measurement, material level monitoring
3. Continuous position feedback for manipulator soft limit & deceleration control
4. Metal workpiece distance detection on conveyor lines
5. Foot pedal position feedback (XS4P18ABxx of the same series is widely used for XPE foot pedals)

⚠️ Installation Notes & Cross-Model Reference

1. Strictly use non-flush mounting. No metal close to the sensor body, otherwise the sensing range will shrink.
2. Set the PLC AI module to 4–20mA current mode, not voltage input.
3. Same analogue sub-series comparison:

XS4P30AB110: 0~10V voltage output

XS4P30AB120: 4~20mA current output (هذا النموذج, mainstream type)

4. Domestic alternative requirement: M30 non-flush, 4–20mA analogue inductive proximity sensor, Sn=15 mm, 12–24 VDC supply.

XS4P30AB120 (M30, Sn15mm, 4–20mA Analogue Inductive Sensor) Field Application Cases

Core feature: Non-flush installation, metal target only, continuous distance output (1.5mm=20mA; 15mm=4mA). It is not a simple limit switch; ideal for continuous position feedback, PID closed-loop control, gap & thickness monitoring. IP67 rated for dusty, oily workshop environments.

قضية 1: Closed-loop position feedback for hydraulic / اسطوانات هوائية (hydraulic stations, machine tool presses, آلات البناء)

Working condition: المطابع, clamping jigs, lifting cylinders. Real-time rod position acquisition for PLC PID speed regulation, soft stop and buffer deceleration to avoid mechanical impact.

تثبيت: Fix XS4P30AB120 at the cylinder tail; mount a square steel target (45×45mm standard target) on the piston rod end. Keep the sensor axially aligned with the target, and keep the working stroke within 1.5~15 mm.

منطق التحكم: 4أماه = 15 مم (تراجعت بالكامل); 20أماه = 1.5 مم (fully extended). The PLC converts current value to displacement and triggers speed reduction when reaching preset positions.

المزايا: Lower cost than pull-wire displacement sensors, زيت & dust resistant, simple installation for short-stroke cylinder buffering control.

✅ Original Accuracy Specifications for XS4P30AB120 (Standard steel target 45×45×1 mm, 25درجه مئوية)

1. Linearity error: ±2 mA

Full span 4～20mA (16mA total range), effective travel 1.5~15 mm (13.5 مم السكتة الدماغية).

±2mA corresponds to ±1.69 mm linear deviation.

2. كرر الدقة: ≤3% Sr

Sr=15 mm → maximum repeat error ≤0.45 mm.

معنى: Readout fluctuation will not exceed 0.45 mm when repeatedly positioning at the same spot.

3. انحراف درجة الحرارة (output current drift): الأعلى 10% خ.س (النطاق الكامل) across -25~+70℃

Range note: Linear performance and accuracy are only guaranteed within the effective working range of 1.5 مم (20أماه) ~ 15 مم (4أماه).

📌 Plain Summary

Excellent repeatability: تقريبا. 0.45 مم, suitable for repeated positioning control.

Moderate linear deviation: ±1.7 mm, not for micron-level precision measurement; it is an industrial coarse-range analogue proximity sensor.

Additional A/D conversion error will be introduced by the PLC AI module, further reducing overall system accuracy.

⚠️ Key Factors Affecting Measurement Accuracy

Target material must be mild steel; stainless steel or aluminium will change sensitivity and increase error.

Strict non-flush mounting; no surrounding metal interference.

Strong welding electromagnetic interference, vibration and wide temperature swings will aggravate drift.
