The SIEMENS 3SE5000-0AD02 is an actuator head designed for position switch models 3SE51/52, featuring a 13 mm stainless steel roller plunger configured as Form C and built to EN 50041 dimensions. It provides precise mechanical actuation with a roller that reduces wear and smooths engagement, while the 3 mm overtravel ensures reliable contact after initial actuation for consistent switching performance. Suited for industrial machine guards, conveyors, and safety interlocks, this head offers straightforward installation to standard switch assemblies and durable rolling contact for long service life in repetitive motion applications.
