Product Description

The SICK 6058146 (CM18-08BNP-EW1) is a high-performance capacitive proximity sensor designed for the non-contact detection of metallic and non-metallic objects. Housed in a durable M18 PBT plastic body, this sensor is engineered to withstand harsh industrial environments, offering exceptional resistance to dust, humidity, and chemical cleaning agents. It features a flush installation design with a reliable sensing range of up to 8 mm, which can be finely tuned using an integrated 11-turn potentiometer for maximum sensitivity.

Equipped with advanced electromagnetic compatibility (EMC) technology, the CM18 ensures stable switching even in environments with high electrical interference. Its dual-output functionality (NPN NO+NC) provides flexible integration into various control systems. With an IP68 and IP69K enclosure rating, the sensor is ideally suited for washdown applications and extreme conditions where standard sensors might fail. This sensor is a versatile solution for object detection and level monitoring, capable of sensing through plastic or glass walls to detect liquids, powders, or solid materials with high precision and long-term reliability.

Key Performance Features

High EMC Resistance: Superior electromagnetic compatibility prevents false switching in noisy electrical environments.
Adjustable Sensitivity: Features an 11-turn potentiometer for precise calibration to specific materials or environments.
Extreme Durability: Rated IP68 (1m water depth for 60 min) and IP69K, making it resistant to high-pressure washdowns.
Material Versatility: Capable of detecting powders, granules, liquids, and solids regardless of color or surface texture.
Visual Indicators: Integrated yellow LED for output status and green LED for operating power indication.
Wide Operating Temperature: Designed to perform reliably in temperatures ranging from –30 °C to +85 °C.

Ideal Applications

Food and Beverage: Level detection of liquids or grains in containers and detection of packaging materials.
Wood Processing: Detecting wood panels, sawdust, or shavings in dusty environments.
Chemical Industry: Non-contact monitoring of aggressive chemicals through plastic or glass tank walls.
Packaging Machinery: Object counting and presence detection of various materials including paper, plastic, and metal.
Plastic Industry: Monitoring the flow and level of plastic granules or pellets in hoppers and supply lines.
