The Allen Bradley 871C-C15R30 is an inductive proximity sensor with essential features tailored for industrial automation. With a sensing distance of 15 mm when working with mild steel, it effectively detects metal objects. The sensor's outer diameter is 30 mm, designed in a threaded plastic housing for easy installation.

This device operates on a supply voltage range of 24 to 250 V AC and can handle a maximum load current of 300 mA. The inrush current is limited to 3 A for a single cycle, while the leakage current is capped at 1.7 mA, ensuring minimal power waste. Voltage drop during operation peaks at 11 V, maintaining efficiency during task execution.

The switching rate of this model is rated at 8 Hz, allowing it to register changes quickly and reliably. The output configuration is normally open (NO), facilitating straightforward integration into existing systems. Wiring is achieved through a 2-wire AC output, connected via a 2-meter long PVC cable with two conductors.

As an unshielded sensor, it operates typically with a hysteresis of 20%, ensuring stability in proximity detection tasks. The overall design and specifications make the 871C-C15R30 a practical choice for diverse applications in automation and control systems.
