Why Choose the Carlo Gavazzi SPB22MT Magnetic Sensor?
The Carlo Gavazzi SPB22MT, also identified as the SP.B.2/2MT, is a rectangular proximity magnetic sensor designed for reliable non-contact position detection in industrial machinery, automation and lift applications. It combines a robust plastic housing with a bistable reed-switch output and is supplied with an integral 2 m PVC cable.
The SPB22MT features a bistable output contact with a maximum switching voltage of 250 V AC, maximum switching current of 3 A and maximum switching power of 100 VA. Its side-shielded construction helps reduce magnetic interference when sensors are installed alongside one another.
With housing dimensions of approximately 24 × 25.5 × 85 mm, an operating temperature range of -25 °C to +75 °C and IP67 protection, the SPB22MT provides a durable sensing solution for demanding industrial environments. The switching distance depends on the magnetic actuator used, with the manufacturer listing an operating-distance range of 5–30 mm for the SPB2 series.

Reliable Bistable Magnetic Position Sensing
The Carlo Gavazzi SPB22MT uses a reed-contact sensing principle in conjunction with an external magnetic actuator. Because sensing is contactless, there is no need for the mechanical engagement associated with conventional limit switches, helping reduce wear in applications involving frequent movement.
Its bistable output maintains the switched state until the appropriate magnetic field causes the contact to change again. The side-shielded design helps reduce unwanted magnetic interaction when multiple sensors are installed close together, while the IP67 enclosure and integral 2 m cable support dependable installation in industrial machinery and automation systems.
Typical Applications
- Lift and elevator position sensing.
- Industrial machine position detection.
- Door and access-panel monitoring.
- Automated production machinery.
- Material handling and conveyor equipment.
- Industrial automation systems.
