The OMRON E2E-CR8B1 detects metallic objects without physical contact using a nominal sensing distance of 0.8 mm. Its recommended setting distance of 0 to 0.5 mm supports precision positioning in suitably configured equipment.
The cylindrical stainless-steel sensor body measures approximately 4 mm in diameter and 25 mm in length, making it useful where installation space is limited.
The sensor uses a three-wire PNP normally open switching circuit with a maximum output load current of 100 mA, enabling connection to appropriately rated sourcing-signal PLC input systems.
The E2E-CR8B1 supports a nominal 12 to 24 VDC supply and operates within a 10 to 30 VDC range, subject to the manufacturer's supply ripple and load requirements.
Its published 3 kHz response frequency under standard test conditions supports small-part detection and fast machine-position sensing. A red indicator LED provides visual switching feedback.
The shielded cylindrical design supports appropriate flush mounting, while the IP67 enclosure rating and pre-wired oil-resistant PVC cable provide protection in compatible industrial environments.

What is the OMRON E2E-CR8B1?
It is a miniature cylindrical inductive proximity sensor with a 4 mm housing diameter, 0.8 mm nominal sensing distance and three-wire PNP normally open output.
What is the rated sensing distance?
The rated sensing distance is 0.8 mm ±15% when tested with the specified metal target. OMRON recommends a setting distance of 0 to 0.5 mm.
Is E2E-CR8B1 a PNP or NPN sensor?
It has a PNP open collector output. The E2E-CR8C1 is an NPN normally open variant and must not be treated as electrically interchangeable without checking the control circuit.
Is the switching function normally open or normally closed?
The E2E-CR8B1 has a normally open output. The E2E-CR8B2 is the corresponding PNP normally closed variant.
What voltage does the sensor require?
The nominal supply voltage is 12 to 24 VDC, with a specified operating range of 10 to 30 VDC and maximum 10% peak-to-peak ripple.
What is the maximum output load current?
The maximum switching load current is 100 mA. Verify the connected controller input or other load before installation.
What is the sensor diameter?
The cylindrical body measures 4 mm in diameter and approximately 25 mm in length. It is not an M4 threaded sensor.
Can the sensor be mounted flush with metal?
Yes. It is a shielded sensor intended for compatible flush-mounting arrangements. Follow the original mounting drawing and clearances.
What is the response frequency?
The published response frequency is 3 kHz under the manufacturer's test conditions. Actual sensing performance depends on the target and installation.
How long is the connection cable?
The commonly specified pre-wired version includes a 2 m cable. Verify the exact cable length and condition of the supplied unit.
Is OMRON E2E-CR8B1 discontinued?
Major electronic component distributors list E2E-CR8B1 as obsolete or withdrawn. Availability of existing units should be confirmed independently, and the latest manufacturer lifecycle information should be checked when planning replacements.
Can E2E-C04S12-WC-B1 replace E2E-CR8B1?
It is listed as a replacement candidate by a distributor, but it has a different rated sensing distance of 1.2 mm. Verify the mounting dimensions, detection range, output type, wiring and machine requirements before substitution.
