EMAS SMS20LSZ-S15 EMAS SMS LEFT EXIT 2NC 5MM SENSE W/O LED M8 CONNECTOR 22MM RECTANGULAR MAGNETIC SWITCH

Why Choose the EMAS SMS20LSZ-S15 Magnetic Door Switch?

The EMAS SMS20LSZ-S15 is a compact 22 mm rectangular magnetic door switch designed for contactless monitoring of machine doors, guards and access points in industrial automation applications. Part of the EMAS SM Series magnetic door switch range, it combines a durable plastic housing with a left-exit configuration, 2NC contacts and an M8 connector for convenient integration into compatible machine wiring systems.

The SMS20LSZ-S15 provides a 5 mm sensing distance and uses a coded, contactless trigger for dependable position detection. Its non-contact magnetic operating principle avoids direct mechanical actuation between the switch and actuator, helping minimise mechanical wear in applications where machine guards and access doors operate repeatedly.

With its compact 22 mm nominal size, connector-based installation and industrial construction, the SMS20LSZ-S15 is well suited to machinery where installation space is limited and easy sensor replacement is desirable. The non-LED design provides a straightforward solution for applications where local visual status indication is not required.
