fslpb2 – mag sensor pl dia 16mm bistable

Why Choose the Carlo Gavazzi FSLPB2 Magnetic Sensor?

The Carlo Gavazzi FSLPB2 is a cylindrical bistable magnetic proximity sensor from the FSLP Series, designed for reliable non-contact position detection in industrial automation, lift, gate and machine-control applications. Its magnetic reed switching principle allows the sensor to respond to an external magnet without requiring direct mechanical contact with the moving component.

Featuring a compact Ø16 mm plastic cylindrical housing, the FSLPB2 uses a bistable reed contact that retains its switched state until the appropriate magnetic field causes it to change state again. This makes it particularly useful in applications where a maintained position signal is required rather than a momentary proximity indication.

The FSLPB2 provides a maximum contact switching voltage of 250 V AC, switching current of 3 A and switching power of 120 VA. It is supplied with an integral 2 m PVC cable, provides IP67 protection and operates across a wide -30 to +80 °C temperature range for dependable industrial use.

Bistable Magnetic Detection for Reliable Position Monitoring

A bistable magnetic sensor provides a maintained switching state rather than simply changing state while a magnet remains within the sensing area. The magnetic field operates the internal reed mechanism, and the bistable arrangement allows the contact state to remain latched until the appropriate magnetic actuation changes it again. This behaviour is valuable in position-monitoring applications where the control system needs to retain an indication after the moving component has passed the sensing point.

The Carlo Gavazzi FSLPB2 combines this bistable operation with a Ø16 mm cylindrical plastic housing, an integral 2 m PVC cable and IP67 environmental protection. The effective operating distance depends on the magnet, its orientation and the installation, with published FSLPB2 data indicating approximately 18 mm from the front and greater than 10 mm from the side.
