Why Choose the EMAS SMB11LC2-B15 Magnetic Door Switch?
The EMAS SMB11LC2-B15 is a compact rectangular magnetic door switch designed for contactless monitoring of doors, guards and access points in industrial machinery and automation systems. As part of the EMAS SM Series Magnetic Door Switch range, it combines a durable plastic body with coded magnetic triggering for dependable position monitoring without mechanical contact between the switch and actuator.
This model features a 1NC + 1NO contact configuration, 5 mm sensing distance and integrated LED indication. Its left-exit cable arrangement provides a defined wiring direction for machine installations, while contactless operation helps minimise mechanical wear and provides resistance to dirt and dust around the sensing interface.
The SMB11LC2-B15 is supplied with an integral 2 m cable and uses the 78 mm rectangular body format. With an IP67 protection rating and an operating temperature range of -25 °C to +70 °C, it is designed for reliable door and guard monitoring in demanding industrial environments.

Reliable Contactless Door and Guard Monitoring
Magnetic door switches provide position information without requiring the mechanical contact and physical actuation associated with conventional limit switches. A coded magnetic actuator operates the sensing element when it reaches the specified detection zone, allowing a control system to determine whether a monitored door or guard is in the required position.
The EMAS SMB11LC2-B15 combines this contactless principle with 1NC + 1NO contacts, LED indication and a rugged IP67 enclosure. Its 5 mm sensing distance, left-exit 2 m cable and compact 78 mm rectangular format make it particularly suitable for integration into industrial doors, guards and automated machinery.
Typical Applications
- Industrial machine door monitoring.
- Machine guard position detection.
- Automated production and assembly equipment.
- Packaging and processing machinery.
- Access-panel position monitoring.
- Conveyor and material handling equipment.
- Industrial automation and control systems.
- OEM machinery and factory automation installations.
