Industrial MS4300B-2 Transmitter

The STI MiniSafe-B MS4300B-2 Transmitter is a compact safety-light-curtain component designed to pair with STI MS4300B-2 receivers and compatible controllers to safeguard industrial machinery. It delivers 19 mm (0.75 in) resolution with a 9.1 m (30 ft) sensing range and comes in a slim 32 x 32 mm (1.25 x 1.25 in) housing for tight installations. Features include quick-disconnect cables, adjustable mounting brackets, and status indicator lights, with versions available for darkroom applications. The MS4300B-2 is intended to work with Universal STI controllers or DuoSafe configurations as part of a multi-opening guarding system, enabling single openings or more complex layouts when paired with the appropriate controller. Built for robust performance, it offers high immunity to electromagnetic interference, ambient light, strobe lighting, and welding flash, helping maintain reliable safety across challenging industrial environments. Typical applications involve safeguarding accessing points on machinery such as presses, shears, and other automated equipment where an operator could reach the hazard zone; the protected-height range is adjustable from 102 mm to 1,626 mm (4 to 64 in), allowing flexible mounting to match guard heights. The small footprint and dedicated transmitter/receiver pairing make the MS4300B-2 a precise, space-conscious choice for MiniSafe safety systems.
