The Allen-Bradley 871A-TS4-D is a robust analog inductive proximity sensor designed for precision and reliability in demanding industrial environments. This sensor provides a variable analog output signal (4-20 mA) that is proportional to the distance between the sensor face and a metal target. Its shielded construction allows for flush mounting without interference, making it ideal for applications requiring accurate position sensing, sorting, or measurement of metallic objects. The durable nickel-plated brass housing and high IP67 rating ensure dependable performance even in harsh conditions with exposure to dust and moisture.
