The Omron E2E-C03N02-CJ-B2 0.3M is a 3mm-diameter cylindrical proximity sensor with a 2mm unshielded sensing range, a PNP normally closed output, and a 0.3-meter cable terminating in an M8 connector. Because it is unshielded, the sensor requires a clearance zone around the head for the electromagnetic field to operate correctly—plan for at least 4mm to 6mm free space around the barrel, per Omron’s derating guidelines for 3mm sensors. The compact 3mm barrel fits into tight spaces where a larger sensor would be impractical, such as detecting small parts on conveyor pallets or in linear actuator end-of-travel monitoring.
How the E2C-X1R5AH compares
The E2E-C03N02-CJ-B2 0.3M gives you a longer 2mm sensing range from a smaller, unshielded barrel, but it demands more empty space around the sensor face. This sensor uses a 0.3 meter pigtail with an M8 connector, while the E2C-X1R5AH is pre-wired with a 3 m cable. If you need a drop-in replacement for an application originally built around the E2C-X1R5AH, you will have to adjust the mounting bracket (clearance for unshielded) and change the cabling—this is not a direct interchange.
Sourcing and lifecycle reality
This sensor is at a mature lifecycle stage—Omron continues to support production, and no EOL notice is recorded. For a procurement buyer, mature means the part has a stable supply base and a well-documented manufacturing history, reducing qualification risk for a new design or a long-term spare. We source this part to order against an RFQ, drawing on a multi-supplier channel to keep the BOM line de-risked—no single-source dependency.
