Product description

The Siemens 3SE5212-0PC05 is a position switch built for industrial automation, featuring a metal enclosure that meets the EN 50047 standard with a 31mm width. It is equipped with a rounded plunger actuator, Form B, designed for specific actuation profiles. The switch offers one M20 x 1.5 device connection and is configured with 2 normally open (NO) and 1 normally closed (NC) slow-action contacts.

This position switch is suitable for applications requiring reliable position detection and control, particularly where slow-action contacts are preferred for their defined switching behavior. The rounded plunger design can be advantageous for certain types of mechanical engagement. Common uses include end-of-travel detection on machinery, safety interlocks, and general automation control in manufacturing environments.
