Industrial MS4428B-2 Transmitter And Receiver Unit

The STI MS4428B-2 is an industrial two-unit transmitter-and-receiver arrangement from STI's Minisafe MS4400B family, designed as a complete safety sensor assembly that can be deployed in guarding configurations where a paired signal path between an emitter and a detector is required. In the Minisafe line, the MS4428B-2FB2 variant is listed as part of the MS4400B-2FB series, described specifically as a 28-range device with up to 50 feet of sensing distance, indicating its suitability for mid-range guard applications within the same product ecosystem. The designation MS4428B-2 appears across both components of the unit, reflecting STI's practice of delivering transmitter and receiver components within a unified model family that promotes compatibility and interchangeability with other MS4400B devices. Users purchase this pair when a compact, coordinated transmitter-receiver solution is needed to establish a reliable, bidirectional signaling channel over moderate distances in industrial environments.
