Purchase SICK 6058146 (CM18-08BNP-EW1) capacitive proximity sensor. Features M18 plastic housing, 8mm sensing range, NPN output, and IP68/IP69K protection.
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.
