What it is and what it does
The Omron E2KQ-X10ME2 2M is an M18 unshielded capacitive proximity sensor with a fluoroplastic resin (PTFE) housing and a 2m PVC cable. It switches NPN NC at 12-24 VDC, designed for level detection or object presence in environments where caustic washdowns or chemical exposure would degrade standard plastic sensors.
Mounting and installation fit
Mounts through an M18x1.5 threaded hole or using a bracket with an 18 mm hole. Unshielded construction means it senses through non-metallic tank walls or pipe, but metal near the sensing face must be accounted for — keep at least twice the sensing distance clear. The 21.8 mm overall body length plus 61.8 mm threaded section is compact for tight panel entries.
What the ratings mean
Rated 12-24 VDC, NPN NC output with a 2m cable. The PTFE coating is the headline difference from the standard E2K-X series: the E2K-X8ME2 (also M18, NPN, NC, unshielded) uses a plastic body rated IP66, while this sensor's fluoroplastic case is specified for chemical resistance — no IP rating listed, but the material choice tells you it's for environments where plastic would craze or swell. Sensing distance on this sensor is not explicitly stated in the listing but the E2K-X8ME2 is rated 8 mm; given the '10' in the model number, expect a 10 mm nominal sensing range. The threaded mounting and wiring are identical, so the E2K-X8ME2 is a functional substitute only if chemical resistance is not required.
