Why Choose the EMAS SMS20LC2-S15 Magnetic Door Switch?
The EMAS SMS20LC2-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 cable arrangement and 2NC contact configuration.
The SMS20LC2-S15 provides a 5 mm sensing distance and uses a coded, contactless trigger for dependable position detection. Because there is no direct mechanical actuation between the switch and actuator, the design helps minimise mechanical wear during repeated opening and closing cycles.
Designed for demanding industrial environments, the SMS20LC2-S15 features IP68 protection, a 2 m cable and an operating temperature range of -25 °C to +70 °C. Its compact 22 mm format and left-exit connection make it particularly useful where installation space is limited and reliable door or guard status detection is required.

Reliable Contactless Door and Guard Monitoring
Magnetic door switches such as the EMAS SMS20LC2-S15 detect the position of a corresponding actuator without requiring direct mechanical actuation. This contactless principle is particularly useful for machine doors and guards that undergo frequent operating cycles, helping reduce wear compared with conventional mechanically actuated position switches.
The SMS20LC2-S15 combines a 2NC contact arrangement, 5 mm sensing distance and coded triggering in a compact 22 mm rectangular housing. Its IP68 protection, left-exit configuration and 2 m cable make it a practical choice for machine builders and automation engineers requiring reliable door and guard position detection.
Typical Applications
- Industrial machine door position monitoring.
- Protective machine guards and access panels.
- Automated production machinery.
- Packaging and processing equipment.
- Industrial enclosures and cabinet doors.
- Conveyor and material handling equipment.
- Machine building and OEM automation systems.
- Contactless door and guard status detection.
