Why Choose the EMAS SMS31RC2-S15 Magnetic Door Switch?
The EMAS SMS31RC2-S15 is a compact 22 mm rectangular magnetic door switch designed for contactless monitoring of machine guards, protective doors and industrial access points. Part of the EMAS SM Series, this model combines a plastic housing, right-side exit, 2NC + 1NO contact configuration and a 5 mm sensing distance.
The SMS31RC2-S15 incorporates an integrated LED indicator for convenient local status indication. Its contactless magnetic operating principle allows the corresponding actuator to operate the switch without mechanical engagement, helping minimise mechanical wear in machinery where guards and doors are opened and closed frequently.
Supplied with a 2 m pre-wired cable, the SMS31RC2-S15 provides a straightforward wired installation while its right-exit configuration supports applications where cable routing is required from that side of the switch. The EMAS SM Series is specified with IP68 protection, making this compact magnetic switch suitable for demanding industrial automation environments.
Key Advantages
- 2NC + 1NO contact configuration provides three switching contacts for compatible monitoring circuits.
- 5 mm sensing distance for contactless guard and door-position detection.
- Integrated LED status indicator assists commissioning and operational checks.
- Right-side cable exit provides a defined cable-routing orientation.
- 2 m pre-wired cable supports straightforward installation.
- Compact 22 mm rectangular housing suits space-conscious machine installations.
- IP68 protection supports installation in demanding industrial environments.
- Non-contact operation avoids mechanical engagement between the switch and actuator.

Reliable Contactless Magnetic Guard Monitoring
The EMAS SM Series uses a magnetic operating principle in which the switch is mounted on the fixed machine structure and the corresponding actuator is installed on the movable guard or protective door. When the actuator enters the switch's sensing zone, the contacts change state so the connected monitoring or control system can determine whether the guard is in the required position without physical engagement between the components.
The SMS31RC2-S15 combines two normally-closed contacts and one normally-open contact with a 5 mm sensing distance and LED indication. Its compact 22 mm rectangular format, right-exit 2 m cable and IP68 protection make it a practical choice for industrial machinery requiring reliable contactless door or guard-position sensing.
Typical Applications
- Industrial machine-guard monitoring.
- Protective door position detection.
- Hinged and sliding machine guards.
- Packaging and processing machinery.
- Automated assembly equipment.
- Robotic and automated production cells.
- Conveyor and material handling machinery.
- Protective enclosures and access panels.
