cl4 – magnet rect 25 x 76 mm

Why Choose the Carlo Gavazzi CL4 Magnetic Unit?

The Carlo Gavazzi CL4 is a robust rectangular magnetic actuator designed for use with compatible Carlo Gavazzi magnetic proximity sensors. As part of the Carlo Gavazzi CL Series magnetic units, it provides a permanent magnetic field for reliable non-contact actuation in industrial position, presence and movement detection applications.

The CL4 is a completely passive magnetic unit and requires no electrical supply, wiring or signal connection. Its permanent Alnico magnet is enclosed within a rectangular plastic housing, providing a durable actuator that can be mounted to moving machinery, doors, guards and other components monitored by a compatible magnetic sensor.

With overall dimensions of approximately 76 × 25 × 18 mm, the CL4 offers a relatively large rectangular magnetic actuator for industrial sensing applications. Carlo Gavazzi specifies a minimum separation of 50 mm between adjacent CL4 magnets, helping ensure reliable operation where multiple magnetic sensing points are installed in close proximity.

Reliable Non-Contact Magnetic Actuation

Magnetic proximity sensing systems use a permanent magnet and a separate sensor to detect the position or presence of a target without requiring mechanical contact between the components. When the CL4 moves within the operating range of a compatible magnetic sensor, its magnetic field actuates the sensing element and causes the sensor to change switching state.

This contactless operating principle helps minimise mechanical wear and supports repetitive switching applications. The CL4 can be attached to a moving machine component, door, guard or other target while the associated sensor remains stationary, providing a simple and dependable method of detecting movement and position in industrial automation systems.
