Why Choose the EMAS SMB30LC2-B15 Magnetic Door Switch?
The EMAS SMB30LC2-B15 is a robust rectangular magnetic door switch designed for reliable contactless monitoring of machine doors, guards and access points in industrial automation systems. As part of the EMAS SM Series magnetic door switch range, it combines a durable plastic housing with a left-exit cable configuration, 2NC+1NO contacts and a practical 2 m cable for straightforward integration into control and monitoring circuits.
This magnetic door switch provides a 5 mm sensing distance and uses a coded contactless trigger to detect its corresponding actuator. Contactless operation reduces the mechanical wear associated with conventional mechanically actuated switches, making the SMB30LC2-B15 well suited to machine guarding, door position detection and repetitive industrial access applications.
With a 78 mm nominal dimension, IP68 protection rating and an operating temperature range of -25 °C to +70 °C, the SMB30LC2-B15 is engineered for dependable performance in demanding industrial environments. Its six-core cable and combined 2NC+1NO switching arrangement provide flexible signalling for compatible machinery and automation systems.

Reliable Contactless Door and Guard Monitoring
Magnetic door switches such as the EMAS SMB30LC2-B15 detect the position of a corresponding actuator using a contactless magnetic principle. This removes the need for direct mechanical actuation whenever a machine door or guard moves, helping reduce wear and supporting dependable operation in applications with frequent access cycles.
The SMB30LC2-B15 combines coded triggering with 2NC+1NO contacts, a 5 mm sensing distance and IP68 environmental protection. Its rectangular plastic housing and left-exit 2 m cable make it suitable for integration into machine guards, access doors, enclosure panels and other industrial equipment requiring reliable position monitoring.
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.
