Omron ZBD3-2 Limit Switch

The Omron ZBD3-2 is a Type 4, multiple-plunger limit switch designed for industrial machinery. This model uses multiple plungers to sense position at several points along a moving part, enabling precise end-of-travel signaling. It features a 1/2 in NPT threaded connection for mounting and wiring entry, supporting straightforward integration into control panels or machine frames. The Type 4 enclosure designation indicates suitability for environments where exposure to dust or water is possible, helping protect the internal mechanism while providing dependable switch actuation when a programmed limit is reached. Use it on conveyor lines, presses, or other equipment requiring multi-point position sensing to control downstream circuits and prevent over-travel.
