It detects non-metallic targets such as plastics, liquids, or wood at a maximum distance of 4 mm — no sensitivity adjustment required, so the detection threshold is fixed from the factory. Rated IP66 with NEMA 4, 12, and 13 enclosures, it holds up in washdown environments or outdoor panels. ## Ratings and wiring notes Supply is 90-250V AC only — this is an AC sensor, not DC rated. The output is a 2-wire SCR (thyristor) normally-open circuit, max load current 200 mA. Because it’s an SCR, expect leakage current typical of thyristors; verify your PLC input can handle that. For DC control circuits you’ll need an interface relay or a different sensor like the DC PNP E2K-X8MF1. The 2 m prewired cable exits the sensor body; bare ends for termination. No sensitivity pots — the fixed threshold eliminates field tuning. The plastic body is 80 mm tall and unshielded, so mounted in steel you may get some range reduction; test in your target material. ## Why not the E2K-X4MY2? The E2K-X4MY2 is mechanically identical — same 12 mm body, same 4 mm sensing range, same SCR AC output — but its contact form is normally-closed instead of normally-open. If your application requires a fail-safe closed loop that opens on detection, the MY2 drops in without any panel rework beyond wiring the NC contact. For NO logic, stick with the MY1.","metaTitle":"Omron E2K-X4MY1 Capacitive Proximity Sensor, 4 mm, IP66","metaDescription":"Omron E2K-X4MY1 capacitive proximity sensor, 12 mm dia., 4 mm sensing distance, SCR NO output, 90-250V AC, IP66.

No sensitivity adjustment needed."},{"question":"How do you wire the E2K-X4MY1 to a PLC input?","answer":"The sensor is 2-wire AC SCR output. Connect one wire to the AC line (L), the other to the PLC input. The input must be AC-compatible and able to handle the sensor's off-state leakage current. For DC PLC inputs, use an interposing relay."},{"question":"What is a form-fit-function replacement for E2K-X4MY1?","answer":"The E2K-X4MY2 is the same sensor with a normally-closed output. If you need normally-open, the MY1 is the current model. For DC applications, consider the E2K-X8MF1 (DC PNP, 8 mm range, 18 mm diameter) but that changes the form factor."},{"question":"Will E2K-X4MY1 drop into a panel specified for E2K-X4MY2 without rewiring?","answer":"Mechanically identical — same mounting, same cable, same supply. The only difference is the output state: MY1 is NO, MY2 is NC. If the panel logic calls for a normally-closed sensor, you will need to rewire the output to an NC input or use MY2."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/omron/E2K-X4MY1","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/E2K-X4MY1 when reusing this data.
