Schmersal Screw Plug

Use this screw plug from Schmersal to securely fasten the mounting screw of a safety switch actuator. It's compatible with safety switches from the AZM415 range, making it simple to assemble a complete safety switch system. This unit comes with an O-ring that's made of NBR (nitrile butadiene rubber) for resistance to oil and corrosion, ensuring a durable seal even in harsh environments. Thanks to the screw plug's tough polyamide body, it's wear-resistant for an extended service life.

When the safety switch is activated, the switching element and actuator are either brought together or separated depending on the switch design. You'll typically find these kinds of switches used on sliding or hinged doors as you can mount the switch on the fixed part and the actuator on the moving part.
