E2K-C Adjustable Long-distance Sensor detects both metallic and nonmetallic objects (water, plastic, etc.).
The OMRON E2K-C is a long‑distance photoelectric proximity sensor that detects both metallic and non‑metallic objects such as water and plastic. The manual provides safety precautions, ordering information, wiring diagrams and detailed specifications for both standard and noise‑resistant models.
It includes guidance on mounting, environmental limits, electrical connections for DC 3‑wire, AC 2‑wire and AC/DC 2‑wire versions, as well as maintenance, inspection and warranty information.

The standard E2K‑C models can sense objects from 3 mm up to 25 mm.
It operates from 12 to 24 VDC (with 10 to 40 VDC ripple) and from 100 to 220 VAC (90 to 250 VAC, 50/60 Hz).
The standard version is rated IP66, while the noise‑resistant version is rated IP65.
E‑type models draw up to 10 mA at 12 VDC and up to 16 mA at 24 VDC.
