The Allen Bradley 871Z-BW5N18-H2 is an 18 mm proximity sensor recognized for its solid performance in various industrial tasks. It detects objects within a sensing distance of 5 mm, providing effective proximity detection for automation processes. The sensor is configured as normally open (N.O.), which allows for straightforward operational integration into control circuits.

Support for rated voltages spans from 20 to 250 volts for both AC and DC, making this sensor highly versatile for different applications. The load current capacity ranges from 5 mA to 250 mA, ensuring compatibility with a range of devices and load specifications. Importantly, it manages inrush currents of up to 4.0 A, demonstrating its ability to handle brief current spikes that may occur during operation.

This model is connected via ToughLink™ cables, made robust for demanding environments, and the wire size employed is 18 AWG. Humidity resistance is another consideration; the 871Z-BW5N18-H2 can handle storage humidity levels up to 80%, provided it is non-condensing. Additionally, it is designed for operation at altitudes reaching up to 1000 meters above sea level, allowing flexibility in installation locations.
