4B Components Analog-output speed sensor
The Milli-Speed loop-powered 4-20 mA analog-output speed switch for PLC, DCS or stand-alone controllers is designed to detect belt slip, belt underspeed, stop-motion, low-speed or zero-speed on conveyors, mixers, fans, grinders and other rotating machines. An inductive sensing device located in the nose of the switch’s enclosure detects a ferrous metal target such as an existing bolt head or device attached to a shaft. The switch is fully encapsulated in a corrosion- and abrasion-resistant, dust-tight and waterproof (IP67) polycarbonate body. It also is CSA Class II, Div. 1 groups E-, F- and G-approved for hazardous-dust environments.
