Sick CM30-25NAP-KW1 Capacitive Sensor

The CM30-25NAP-KW1 by Sick features a rugged cylindrical thread design with an M30 x 1.5 thread and Ø 30 mm diameter, allowing for easy installation in standard industrial setups. Its wide sensing range of 4 mm to 25 mm enables reliable detection of a variety of non-metallic objects such as plastic, paper, and liquids, even through container walls. Designed for non-flush mounting, this sensor provides greater detection distance compared to flush-type models, making it suitable for applications where sensor clearance is required.

Operating at a frequency of 10 Hz, the sensor is built for steady and low-speed detection tasks. It is equipped with a durable 2-meter cable for flexible wiring in space-constrained panels and operates on a 2-wire AC connection, compatible with various control systems. The output can be configured as either Normally Closed (NC) or Normally Open (NO), depending on application needs. Sensitivity adjustment is available via an 11-turn potentiometer, allowing fine-tuning based on material properties or installation distance.

With an IP67-rated housing conforming to EN 60529, the Sick CM30-25NAP-KW1 Capacitive Proximity Sensor is highly resistant to dust and water, making it ideal for harsh environments such as food processing units, chemical packaging zones, and high-humidity industrial lines. Backed by Sick’s legacy of precision engineering, this model delivers dependable, long-term sensing performance.

The CM30-25NAP-KW1 Capacitive Proximity Sensor is specially designed for industries where detecting non-metallic materials is critical. It’s commonly used in packaging machines to detect plastic trays or cardboard layers, in bottling lines to sense liquid levels through plastic containers, and in storage silos to monitor grain or powder fill levels. With its 25 mm sensing distance, it helps ensure that materials are reliably detected before downstream operations are triggered.

Maintenance engineers appreciate the sensor’s adjustable sensitivity, which allows it to be tailored to different material types without requiring model changes. Its robust enclosure and cable connection mean fewer sensor failures, less maintenance time, and longer operational uptime in dusty, wet, or vibration-heavy environments. Whether mounted on fixed machinery or moving gantries, this sensor maintains accuracy across wide detection zones.

Engineering students and automation trainees can clearly understand the working of this capacitive proximity sensor through real-life use cases like bin detection, level control, and presence sensing in production lines. As more factories in India move toward smart automation, reliable sensors like the CM30-25NAP-KW1 Capacitive Proximity Sensor become critical components in building efficient and error-free industrial systems.
