Banner Engineering SI-MAG1SM W 30 56988 Safety Door Switch

The Banner SI-MAG1SM W/30 is a magnetic, non-contact safety door switch designed to secure guarded access on industrial equipment. This thermoplastic, rectangular sensor (88 x 25 mm, 13 mm thick) pairs with a coded-magnet system (SI-MAG1MM) and uses a reed-relay output with 1 NC/1 NO safety contacts for reliable interlock circuits, delivering PL e, SIL CL3, and Cat 4 safety performance. The standard connection harness is 3 meters long, with the W/30 variant offering a 9-meter (30 ft) cable for longer reach, and the entire unit is washdown-rated with IP67 protection for harsh environments. Actuation is described as standard, with a switching distance of about 3 mm (ON at close proximity), making it a compact, robust solution for protecting personnel around guarded doors while enabling straightforward installation and concealment.
