The 871TM-BH2N12-N3 inductive sensor by Allen Bradley is crafted for reliable operation in demanding industrial applications. This sensor utilizes a 2-wire AC/DC model, accommodating a voltage range of 20 to 250 volts, facilitating broad compatibility with various control systems. The output configuration operates in a normally open (N.O.) mode, providing straightforward integration into PLC interfacing applications.

Measuring 12 mm in barrel diameter, the compact sensor design is particularly advantageous for installations in limited spaces. Its short barrel type and metal face enhance robustness, ensuring durability in tough environments. The connection is managed through a mini quick disconnect, which simplifies setup and maintenance processes.

The sensor is shielded to guard against electrical interference, making it a dependable choice for industrial setups where electromagnetic noise is present. While it is designed for embedded or panel mounting, it also comes with standard protection, although it is not suitable for immersible applications. The sensing capability is effective up to 2 mm, providing precise detection functions in automation and control contexts.
