Why Choose the EMAS SMS11RSZ-S15 Magnetic Door Switch?
The EMAS SMS11RSZ-S15 is a compact 22 mm rectangular magnetic door switch designed for non-contact monitoring of machine guards, protective doors and industrial access points. Part of the EMAS SM Series, this model features a plastic housing, right-side exit, 1NC + 1NO contact configuration and a 5 mm sensing distance.
The SMS11RSZ-S15 incorporates an LED status indicator for convenient local indication and uses an M8 4-pin connector rather than a permanently attached cable. This connectorised design can simplify installation, servicing and replacement where compatible machine wiring and cordsets are used.
With IP68 protection and an operating temperature range of -25°C to +70°C, the SMS11RSZ-S15 is designed for demanding industrial environments. Its contactless, coded magnetic triggering principle avoids mechanical engagement between the switch and actuator, while EMAS specifies resistance to dirt and dust for the SM Series design.

Compact Coded Magnetic Door and Guard Monitoring
The EMAS SM Series uses a contactless magnetic operating principle, with the switch installed on the fixed machine structure and the corresponding coded actuator positioned on the movable guard or door. As the actuator enters the specified sensing zone, the magnetic switch changes contact state so the connected monitoring or control system can determine the position of the guard without mechanical engagement between the two components.
The SMS11RSZ-S15 combines 1NC + 1NO contacts, a 5 mm sensing distance and LED indication in a compact 22 mm format. Its M8 4-pin connector provides a detachable connection method, while the IP68 enclosure rating and -25°C to +70°C operating range support installation in demanding industrial environments.
Typical Applications
- Industrial machine-door monitoring.
- Protective machine-guard position detection.
- Hinged and sliding machine guards.
- Packaging and assembly machinery.
- Automated manufacturing equipment.
- Conveyor and material handling machinery.
- Protective enclosures and access panels.
- Industrial automation and machine monitoring systems.
