OMRON E2B-M12KN05-M1-B1 is a 12 mm diameter cylindrical proximity sensor from the E2B series, offering a 5 mm unshielded sensing distance with PNP normally open output and M12 connector. The short-body brass housing suits tight panel or machine-mount applications where space is limited and a flush-mounted sensor isn't required.
Selection note
Unshielded construction extends the electromagnetic field, achieving 5 mm range without a larger sensor. PNP output is sourcing; normally open switches when metal enters the 5 mm zone.
