Banner Engineering SI-MAG1SM W 30 Magnetic Safety Interlock Switch

The Banner SI-MAGB1SM W/30 is a non-contact magnetic safety interlock switch from Banner’s SI-MAG series, designed to secure guard doors and gates without physical contact. It uses a rectangular sensor with a thermoplastic housing measuring 88 x 25 mm and ships with a 30 ft (9.1 m) cable for flexible mounting, and it is used with the SI-MAGB1MM companion magnet/actuator to form a complete safety interlock pair. The interlock offers a repeat switching accuracy of ±0.1 mm, ensuring reliable door sensing in demanding industrial environments, while providing standard actuation and a straightforward installation. For safety-critical installations, Banner notes that the switch should be used with Banner safety controllers or GM-FA-10J safety relays (or an approved equivalent). This SI‑MAGB1SM W/30 model embodies Banner’s magnetic, non-contact approach to guarding, reducing wear compared with mechanical interlocks and supporting robust performance in washdown or harsh environments while accommodating a 30 ft cable length for versatile mounting.
