The Allen Bradley 871TM-DH10CP30-D4 model is a compact 3-wire DC inductive proximity sensor designed for various applications. Operating over a voltage range of 10 to 30 V DC, this sensor is suitable for many industrial environments. With a nominal sensing distance of 10 mm (0.39 in.), it efficiently detects metallic objects nearby. The sensor has a maximum switching frequency of 40 Hz, allowing it to respond effectively in dynamic situations.

When delivering a load current of up to 200 mA, the device ensures minimal voltage drop, remaining within 1 V DC during operation at that current level. The leakage current is capped at ≤ 10 µA, minimizing the potential for unintended triggering. The sensor's repeatability is within 10% at a stable temperature, complemented by a typical hysteresis of 10% for enhanced accuracy.

The output configuration is normally closed and follows a PNP sourcing logic, suitable for various control setups. This model is shielded, which enhances its functionality by reducing electromagnetic interference. In terms of protective capabilities, it features false pulse suppression, transient noise immunity, reverse-polarity protection, and short-circuit protection that activates at around 340 mA, further ensuring its reliability in operational use.
