🔌 Wiring Definition (3-コアケーブル)
茶色: DC+ (Positive power)
青: 直流(Negative power)
黒: 4~20mA signal output → connect to PLC analogue AI current input channel
動作原理: The closer the metal target is to the sensor, the higher the output current (rising from 4mA to 20mA).
15 mm distance = 4 ミリアンペア; 1.5 mm distance = 20 ミリアンペア.
Used for continuous displacement feedback and closed-loop control, not just discrete on/off switching.
📎 Typical Applications
- Continuous position closed-loop feedback for hydraulic cylinders / pneumatic actuators (hydraulic presses, tooling clamps, リフティングシリンダー)
- Workpiece thickness & gap measurement, material level monitoring
- Continuous position feedback for manipulator soft limit & deceleration control
- Metal workpiece distance detection on conveyor lines
- Foot pedal position feedback (XS4P18ABxx of the same series is widely used for XPE foot pedals)
⚠️ Installation Notes & Cross-Model Reference
- Strictly use non-flush mounting. No metal close to the sensor body, otherwise the sensing range will shrink.
- Set the PLC AI module to 4–20mA current mode, not voltage input.
- Same analogue sub-series comparison:
XS4P30AB110: 0~10V voltage output
XS4P30AB120: 4~20mA current output (このモデル, mainstream type)
- 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) 現場での応用事例
コア機能: 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, ギャップ & thickness monitoring. IP67 rated for dusty, oily workshop environments.
場合 1: Closed-loop position feedback for hydraulic / 空気圧シリンダー (油圧ステーション, machine tool presses, 建設機械)
Working condition: Presses, clamping jigs, リフティングシリンダー. Real-time rod position acquisition for PLC PID speed regulation, soft stop and buffer deceleration to avoid mechanical impact.
インストール: 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.
制御ロジック: 4mA = 15 mm (fully retracted); 20mA = 1.5 mm (fully extended). The PLC converts current value to displacement and triggers speed reduction when reaching preset positions.
利点: Lower cost than pull-wire displacement sensors, 油 & dust resistant, simple installation for short-stroke cylinder buffering control.

✅ Original Accuracy Specifications for XS4P30AB120 (Standard steel target 45×45×1 mm, 25℃)
- Linearity error: ±2 mA
Full span 4～20mA (16mA total range), effective travel 1.5~15 mm (13.5 mmストローク).
±2mA corresponds to ±1.69 mm linear deviation.
- Repeat accuracy: ≤3% Sr
Sr=15 mm → maximum repeat error ≤0.45 mm.
意味: Readout fluctuation will not exceed 0.45 mm when repeatedly positioning at the same spot.
- 温度ドリフト (output current drift): マックス 10% FS (フルスケール) across -25~+70℃
Range note: Linear performance and accuracy are only guaranteed within the effective working range of 1.5 mm (20ミリアンペア) ～ 15 mm (4ミリアンペア).
📌 Plain Summary
Excellent repeatability: 約. 0.45 mm, 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.
