Unshielded construction means the sensor needs a free zone around the face — plan for twice the rated sensing distance to the side for reliable detection. NPN output is intended for sinking inputs; verify the PLC or controller input type before wiring. Pre-wired PVC cable is robust for dry indoor environments but should be protected from coolant or oil splash.","metaTitle":"Omron E2B-M30KN20-WP-C1 2M Proximity Switch, NPN NO, 20mm","metaDescription":"Omron E2B-M30KN20-WP-C1 2M unshielded cylindrical proximity switch: NPN normally open output, 20mm sensing distance, 2m PVC cable, 30mm diameter.

If your control input is designed for a sinking signal, the PNP version will not drive it without reconfiguration or a level converter. A deviation from the AML would be required."},{"question":"What is the mounting pitch and clearance requirement?","answer":"The sensor body is 30mm diameter with metric thread, short barrel. As an unshielded type, it requires a free zone around the sensing face of at least 40mm (twice the rated sensing distance) to avoid false triggers from proximity to metal."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E2B-M30KN20-WP-C1-2M","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/omron/E2B-M30KN20-WP-C1-2M when reusing this data.
