The EMAS SMS21LSZ-S15 is a compact 22 mm rectangular magnetic door switch from the EMAS SM Series, designed for contactless monitoring of doors, guards and moving machine elements in industrial automation applications. Its plastic housing and contactless magnetic operating principle provide reliable position detection while avoiding the mechanical engagement associated with conventional limit switches.
This exact model features a 2NC contact configuration, a 5 mm sensing distance and an integrated LED indicator. The two normally-closed contacts provide dual switching paths for compatible control arrangements, while the LED gives convenient local visual status indication during operation, commissioning and maintenance.
The SMS21LSZ-S15 is a left-exit version equipped with an M8 4-pin connector. It also provides IP68 protection and an operating temperature range of -25 °C to +70 °C, making it a robust compact solution for industrial door and guard position monitoring in demanding environments.
The EMAS SM Series uses contactless magnetic triggering to detect the position of a corresponding actuator without requiring direct mechanical engagement. This operating principle helps reduce wear while also providing resistance to contamination and dust around the sensing interface, making the system well suited to repetitive industrial door and guard movements.
The SMS21LSZ-S15 combines 2NC contacts, 5 mm sensing distance, LED status indication and an M8 4-pin connector in a compact 22 mm rectangular housing. Its IP68 environmental protection further supports reliable integration into industrial machinery and automation systems where robust position monitoring is required.
