The EMAS SMB21LC2-B15 is a compact rectangular magnetic safety door switch designed for reliable monitoring of machine guards, access doors and protective covers in industrial safety applications. Featuring a plastic housing, left exit cable orientation, dual NC contacts, integrated LED indication and a 2 m cable connection, it provides dependable guard position monitoring for safety circuits.
The SMB21LC2-B15 uses a magnetic coded switching principle to detect whether a safety guard or access door is open or closed. Its 2NC contact configuration provides redundant switching channels, while the built-in LED indication allows quick visual confirmation of operating status during installation and maintenance.
With its compact 78 mm rectangular housing, left-side cable exit and 5 mm operating distance, the EMAS SMB21LC2-B15 is ideal for machine guarding applications including industrial machinery, automated production equipment and safety interlocking systems.
Magnetic safety switches such as the EMAS SMB21LC2-B15 provide reliable monitoring of machine guards and access doors without physical contact. This helps prevent machinery operation when protective guarding is open, supporting safer industrial working environments.
The dual NC contact arrangement allows connection to safety relays and machine safety controllers, providing dependable feedback for protective door monitoring systems. The integrated LED indication helps simplify commissioning and fault checking during system operation.
