SICK 6051030 CM12-08EBP-KC1 Teach-In Capacitive Sensor

Technical Overview

The SICK CM12-08EBP-KC1 is a capacitive proximity sensor with an M12 × 1 threaded housing and PNP/NPN with NC or NO function output. It detects nearby material by evaluating changes in capacitance, supporting qualified metal and nonmetal targets. Its specified range is 0.5–8 mm non-flush or 0.5–4 mm flush, with actual reach dependent on material and installation. The local button and external wire teach-in adapts sensitivity to the target and surroundings. The sensor operates from 10–36 V DC at 15 Hz and connects through an M12 four-pin male connector. Its plastic housing provides IP68 protection, and two PA12 mounting nuts are included. Material reduction factors guide commissioning.

Industrial Applications

1. Checking a nonmetal part in an assembly fixture

An assembly fixture can place a qualified nonmetal part near the sensing face and use the PNP/NPN with NC or NO function signal to confirm its local presence. The local button and external wire teach-in adapts sensitivity to the actual target and surrounding fixture. Commissioning compares empty and occupied states at the installed spacing, taking the documented material reduction factors into account.

Problem Solved

A local presence signal helps the controller detect a missing part before the next assembly step, without requiring a metal target on the component or a contact actuator.

Part presence Nonmetal targets Capacitive sensing

2. Detecting a liquid at a point in a nonmetal vessel

A suitable nonmetal vessel can position the sensor outside its wall at the desired detection point. After testing the actual wall, liquid and spacing, the local button and external wire teach-in sets a threshold between empty and filled conditions. The PNP/NPN with NC or NO function output provides a discrete point-level event to a compatible controller; the specified range remains subject to the installed materials.

Problem Solved

A qualified external point-level signal helps the process controller identify liquid reaching the monitored height while avoiding a probe inside the vessel and preserving the vessel wall.

Point level External mounting Qualified vessel wall

3. Monitoring granulate at a feed inspection window

A granulate feeder can place the sensor beside a suitable nonmetal inspection window to check whether material occupies the monitored location. The local button and external wire teach-in is set using the actual granulate, window and installation spacing. Empty and filled tests, including expected moisture and buildup conditions, qualify the discrete output before it is used to coordinate feeding.

Problem Solved

A local material-presence event helps the controller identify an empty feed location or arrival of replenishment material, supporting feed sequencing without placing a mechanical paddle in the granulate.
