The Omron E3SR87 is a retroreflective photoelectric sensor from the E3S series, with a PNP output and a sensing range of 100 to 300 mm. It uses an infrared LED emitter and terminates in an M12 connector. Housing is rated IP67, so it handles washdown and dusty environments without a secondary enclosure. Supply range is 10 to 30 VDC, with a maximum load current of 100 mA. Response time is 1 ms, and the output can be set to light-on or dark-on switching. That covers most standard PLC inputs and relay loads without a separate amplifier. Typical applications: conveyor presence, packaging line product detection, pallet positioning. The 300 mm maximum range assumes a standard 50 mm reflector; shorter distances down to 100 mm work without issue.

Product details
Frequently asked questions
What is the sensing distance of the E3SR87?
Retroreflective mode with a standard reflector gives a sensing range from 100 mm to 300 mm.
Is the E3SR87 PNP or NPN?
It is PNP output. The NPN equivalent is the E3SR67.
What are the key electrical and environmental ratings?
Supply 10–30 VDC, load current 100 mA, response time 1 ms, IP67, operating temperature 0 to 40 °C.
How does the E3SR87 differ from the E3SR86?
The E3SR86 uses a visible red LED instead of infrared and has a longer maximum sensing distance of 1 m. Both are PNP, IP67, M12-terminated, and share the same housing dimensions.
Where can I obtain the E3SR87?
Sourced to order via RFQ. No current stock status is published; lead time is confirmed at quote stage.
