Omron E3ZM-LS89H Photoelectric Sensor
Omron E3ZM-LS89H is a fixed-distance BGS reflective photoelectric sensor specified for a 10 to 200 mm sensing range using 100 × 100 mm white paper as the reference target. Its 660 nm red LED provides the optical source, while background suppression helps establish the required target zone with reduced response from surfaces beyond it. The PNP output transfers the switching state to compatible PLC and machine-control circuitry, and Light-ON or Dark-ON operation can be selected through the cable connection. Operating power is 10 to 30 VDC, with current consumption specified at 25 mA maximum. An M8 4-pin connector provides electrical integration, while response time is 1 ms maximum. The E3ZM-LS89H extends fixed-distance sensing within the 200 mm BGS sensor range across Omron Sensor Products.

The Omron E3ZM-LS89H Photoelectric Sensor provides fixed-distance BGS reflective sensing across a specified range from 10 to 200 mm using 100 × 100 mm white paper as the reference target. A 660 nm red LED supplies the optical source, while background suppression keeps the switching requirement associated with the selected target zone rather than distant surfaces. Its PNP output supports load supply voltage up to 30 VDC and load current up to 100 mA. The sensor operates from 10 to 30 VDC and consumes 25 mA maximum. Light-ON or Dark-ON operation is selected through the cable connection, while response time is 1 ms maximum. An M8 4-pin connector provides the electrical interface, with yellow operation and green stability indicators supplying visual status.
Where an Omron PNP BGS sensor needs a wider fixed-distance span than the 100 mm LS86H, the relevant model is the E3ZM-LS89H. Its 200 mm upper limit doubles the maximum stated distance of the LS86H while retaining connector-based installation and a 10 to 30 VDC supply range. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C. Reversed power-supply polarity protection, output short-circuit protection, reversed output-polarity protection, and mutual-interference protection are specified. SUS316, methacrylic resin, PES, PEEK, and fluoro rubber are listed among the supplied materials. For a related fixed-distance PNP model with a shorter 10 to 100 mm range, see E3ZM-LS86H.
