The molded-plastic block housing conforms to EN 50047, and the IP65 rating means the switch body and actuator seal against water jets and airborne particulates — it holds up in washdown zones and on crusher walkways where airborne ore dust is the norm. The actuating element is a roller lever, so it tracks cam profiles or sliding door edges without binding. The switching function is mechanical positive opening (confirms this), meaning the NC contact is forced open by a non-resilient linkage when the actuator is depressed — this is the safety-relevant feature that lets the switch serve as a position interlock in a safety circuit, not just a limit flag. It carries one NC contact and zero NO contacts, so it is wired as a normally-closed safety input to the AS-i bus. The AS-i connection uses the insulation displacement method, which punches through the cable jacket without stripping — a time-saver on a long bus run and one less failure point in a high-vibration environment. No phase-out notice or last-time-buy date is available. Fastening is screw fixing. The housing design is a block profile per EN 50047. The AS-i connection uses the insulation displacement method — the cable sits in the slot, the cap is pressed down, and the contact blades pierce the insulation. No wire stripping, no ferrule, no screw terminal to vibrate loose.","metaTitle":"Siemens 3SF3210-0EV00-0BA2 Position Switch, AS-i, IP65, 1NC","metaDescription":"Siemens 3SF3210-0EV00-0BA2 communication-capable position switch with AS-i adapter.

To use it, you need an AS-i master and a yellow AS-i flat cable.
