Product details

Omron E2K-C25MY1 capacitive proximity sensor: 34 mm cylindrical, 25 mm max sensing distance, two-wire SCR NO output, 90-250 V AC supply. IP66, NEMA 1/4/12/13 rated, adjustable sensitivity, 2 m prewired cable.

Picking the right variant

Need normally-closed logic? Use the E2K-C25MY2 -- same specs except contact form. For DC applications with NPN output, the E2KC25ME1 has a 10-30 V DC supply and same 25 mm range.

Wiring and installation

Connect one wire to AC line (90-250 V AC) and the other to the load (up to 200 mA). The sensor switches the load when it detects material within the adjustable 25 mm range.

Frequently asked questions

What is the difference between E2K-C25MY1 and E2K-C25MY2?

The MY1 has a normally-open (NO) output; the MY2 has a normally-closed (NC) output. All other specs are identical.

What is the difference between E2K-C25MY1 and E2KC25ME1?

The ME1 runs on 10-30 V DC with an NPN output (three wires), while the MY1 runs on 90-250 V AC with a two-wire SCR output. They share the same housing and 25 mm sensing range.

How do I wire the E2K-C25MY1 two-wire SCR output?

Connect one wire to AC line (90-250 V AC), the other to the load, and the load's other side to neutral. The sensor switches the load (up to 200 mA) when it detects the target within the adjustable sensing range.

Can the E2K-C25MY1 sense liquids through a tank wall?

Capacitive sensors can detect materials through non-metallic walls. With a 25 mm maximum sensing range and adjustable sensitivity, it can be tuned for tank wall applications, but actual performance depends on wall material and thickness. The 25 mm range is calibrated for standard conditions.
