Why Choose the Carlo Gavazzi MSA1 Rectangular Magnetic Sensor?
The Carlo Gavazzi MSA1 is a compact rectangular magnetic proximity sensor designed for reliable non-contact position and entry monitoring in industrial and access-control applications. Part of the Carlo Gavazzi M and MS magnetic sensor series, it uses a miniature reed contact to provide a simple and dependable normally open switching function.
The MSA1 features a normally open dry reed contact with a maximum switching current of 750 mA, maximum switching power of 10 VA and maximum switching voltage of 250 V AC. Its magnetic operating distance extends up to 35 mm, providing useful installation tolerance for doors, guards and moving machine components.
A distinctive feature of the MSA1 is its suitability for entry-control and cable-cut detection applications. It is supplied with the matching CL2 magnetic actuator and a 2 m PVC cable, while its compact plastic housing, IP67 protection and -25 to +75 °C operating temperature range support dependable use in demanding industrial environments.

Reliable Non-Contact Magnetic Position Detection
Magnetic proximity sensors use a reed contact that changes state when a suitable magnetic actuator enters the sensing area. In the MSA1, the normally open reed contact closes when the supplied magnetic unit approaches the sensor, providing a simple electrical indication of door, guard or moving-part position without direct mechanical contact.
Because the sensing elements do not need to touch, the system experiences minimal mechanical wear and is suitable for repeated operation. The MSA1 is particularly useful in entry-control applications because its design can also be used to detect interruption of the sensor cable, while the IP67 housing supports reliable operation in industrial environments.
Typical Applications
- Door and entry-control monitoring.
- Machine guard and access-panel position detection.
- Cable-cut detection systems.
- Industrial automation and machinery.
- Cabinet and enclosure door monitoring.
- Non-contact position sensing of moving components.
