sb2/s5 – rect mag sensor pl bistable

Why Choose the Carlo Gavazzi SB2S5 Magnetic Sensor?

The Carlo Gavazzi SB2S5, also identified as SB2/S5, is a compact rectangular magnetic proximity sensor with a bistable reed contact designed for reliable non-contact position detection in industrial machinery and automation systems. As part of the Carlo Gavazzi S series, it uses magnetic actuation to provide dependable switching without requiring physical contact between the sensor and the moving component.

The SB2S5 features a bistable dry reed contact and a maximum switching distance of 28 mm. Bistable operation allows the contact to retain its switched state after the actuating magnetic field is removed, making the sensor particularly useful for maintained position indication and applications where the last detected state needs to be retained.

With a maximum switching voltage of 250 V AC, maximum switching current of 3 A and maximum switching power of 100 VA, the SB2S5 provides a straightforward interface for compatible industrial control circuits. The special S5 version is supplied with a short 0.24 m PVC cable, while its durable plastic housing and IP67 protection rating support reliable operation in demanding industrial environments.

Reliable Bistable Magnetic Position Detection

Magnetic proximity sensors use the field generated by a suitable permanent magnet to operate an internal reed contact without requiring mechanical contact between the sensor and the moving component. This provides a simple and durable method of monitoring machine mechanisms, doors, covers and other moving equipment while reducing mechanical wear associated with conventional contact-operated switches.

The bistable operating principle of the Carlo Gavazzi SB2S5 allows the reed contact to retain its switching state after the actuating magnetic field is removed. Combined with its compact rectangular housing, short cable connection and IP67 protection, this makes the SB2S5 well suited to maintained position detection in industrial machinery and automation installations.

Typical Applications

• Industrial position and presence detection.
• Machine mechanism position monitoring.
• Door, cover and access-panel sensing.
• Conveyor and material handling equipment.
• Automated manufacturing machinery.
• End-position detection on moving mechanisms.
• Industrial control and automation systems.
• Applications requiring bistable magnetic switching.
