Product description

The Siemens 3SE5112-0BC02 is a high-quality position switch housed in a 40 mm metal enclosure, conforming to EN 50041 standards. It features a device connection with a 1x M20 x 1.5 thread and includes 1 normally open (NO) and 1 normally closed (NC) slow-action contacts. This model is equipped with a rounded plunger made of stainless steel, offering 3 mm of overtravel for added flexibility in actuation.

This switch is ideal for detecting the end-of-travel of moving machine parts, safety monitoring, and control functions in demanding industrial environments. The rounded plunger and overtravel feature can be advantageous in applications where precise alignment might be challenging or where a slight margin of error is acceptable.

Frequently asked questions

What is the benefit of the 3mm overtravel on the 3SE5112-0BC02 rounded plunger?

The 3mm overtravel on the rounded plunger of the Siemens 3SE5112-0BC02 allows for a small degree of misalignment or a slight overshoot of the actuating mechanism without damaging the switch or preventing its operation. This provides increased tolerance in dynamic applications.
