Banner Engineering SI-MAG2SM Magnetic Safety Interlock Switch Sensor

Banner Engineering's SI-MAG2SM Magnetic Safety Interlock Switch Sensor is a non-contact, magnetically actuated position sensor that forms the sensing half of Banner's SI-MAG interlock family when paired with the SI-MAG2MM actuator. This compact rectangular device measures 43 x 26 x 13 mm and uses a thermoplastic housing with IP67 protection, 4-pin (4-wire) cabling, and a reed-relay output offering 1 NC and 1 NO contacts. It operates from -25 to 70 C, and in safety terms carries a Cat 4 safety category, SIL CL 3, and PL e rating, reflecting its suitability for high-assurance interlock applications. The unit is specified for a SISTEMA B10d of 2 million cycles, emphasizing durability under repeated interlock cycles. Designed for use in door, hood, or gate interlock configurations, the SI-MAG2SM provides reliable non-contact sensing while reducing wear compared with mechanical interlocks, and its compatibility with the SI-MAG2MM actuator enables integrated interlock solutions across Banner's SI-MAG safety system.
