The E2K-L26MC1 is a capacitive liquid level sensor sized to clamp onto plastic pipes from 12 to 26 mm diameter. It detects liquid level through the pipe wall without contact, outputting an NPN normally-open signal at 12 to 24 VDC. The 20 x 33 x 34 mm body packs into tight pipe runs — useful when you're retrofitting level detection on existing piping without tearing out support brackets. Unshielded design lets it sense through the pipe wall; it's specified only for plastic pipes because capacitive sensors need a non-metallic barrier.
Pipe clamp fit
The sensor mounts directly to the pipe with a built-in clamp. The PVC cable exits the back, 2 m length standard. Heat-resistant ABS case stands up to ambient heat near process lines.
vs E2KQ-X10ME2 2M
The E2KQ-X10ME2 2M shares the same NPN output and 12-24 VDC supply, but differs in mounting (bracket/threaded vs pipe clamp) and output logic (NC vs NO). If your application requires normally-closed sensing or a standard 18 mm threaded barrel, the E2KQ-X10ME2 is the alternative; but for direct pipe-mount NO detection, the E2K-L26MC1 is the fit.
