SICK CM18-08BPP-EC1 Threaded Barrel Capacitive Proximity Sensor CM 8 mm, M18 x 1 PNP 200mA 36V 36 V dc

SICK Series CM Proximity Sensor, 8mm Maximum Detection, M18 x 1 Thread Size - CM18-08BPP-EC1

This proximity sensor is a capacitive device designed for industrial detection tasks where non-contact sensing of materials is required. It operates from standard DC supplies and connects via an M12 4-pin male connector, offering complementary PNP switching output and user-adjustable sensitivity for integration into automated systems.

Features & Benefits

• 10–36 V DC supply supports common industrial voltages
  50Hz switching frequency enables regular cycle detection
  200mA continuous switching current handles moderate loads
  IP67 IP68 IP69K enclosure allows use in wet or washdown areas
  Potentiometer sensitivity adjustment permits fine tuning

**Applications**

• Suitable for level detection of bulk materials in bins
  Ideal for presence sensing of plastics and glass components
  Used for object detection on conveyors in washdown processes
  Can be used for detecting liquids through non-metallic containers
  Suitable for machine control tasks in food processing environments

What temperature range can it withstand during operation?

It functions across –30°C to +85°C ambient temperatures for typical industrial settings.

How is the sensor mounted for flush installation?

It fits into an M18x1 threaded barrel and is supplied with two PA12 plastic mounting nuts for secure flush mounting.

What protections are provided against electrical faults?

The device includes short-circuit protection, reverse-polarity protection and power-up Pulse suppression to protect against common wiring errors.

Which materials affect sensing range and how much?

Different target materials reduce the effective sensing range by specific factors, for example PVC ≈0.4, oil ≈0.25, and metal approximately 1.

What indicators and adjustment options are available on the unit?

It features an operating LED and an output LED Plus a screwdriver-adjustable potentiometer for sensitivity setting.
