SP.A.1/S2 – Magnetic rectangular prox. sensor
Carlo Gavazzi SP.A.1/S2 rectangular magnetic proximity sensor with dual normally closed contacts, 24 V DC supply and IP67 protection for industrial position sensing and switching applications.
Why Choose the Carlo Gavazzi SP.A.1/S2 Magnetic Proximity Sensor?
The Carlo Gavazzi SP.A.1/S2 is a robust rectangular magnetic proximity sensor designed for reliable non-contact position detection and load switching in industrial machinery and automation systems. As part of the Carlo Gavazzi SPA1 magnetic sensor series, it combines two normally closed outputs in a compact rectangular housing for signalling and higher-power switching applications.
The SP.A.1/S2 incorporates two separate normally closed contacts. One provides a low-power 5 VA signalling output, while the second provides a 100 VA high-power output suitable for switching more demanding loads. This dual-contact arrangement enables the sensor to perform both machine-status signalling and load-control functions from a single sensing device.
Operating from a 24 V DC supply, the SP.A.1/S2 features an IP67-rated ABS Class V0 housing measuring just 90 × 20 × 16 mm. Its rugged construction, long contact life and wide operating temperature range make it well suited to industrial position sensing, machine guarding, access detection and automated equipment.

Reliable Magnetic Position Sensing for Industrial Machinery
Magnetic proximity sensors detect the presence or movement of a suitable magnetic actuator without requiring direct mechanical contact. This contactless sensing principle reduces mechanical wear and provides dependable position feedback for machines, guards, doors and moving components.
The Carlo Gavazzi SPA1 series is particularly useful where separate signalling and load-switching functions are required. The SP.A.1/S2 combines a low-power contact for control-system signalling with a higher-power contact for switching larger loads, helping simplify machine wiring and component selection.
Typical Applications
- Industrial machine position detection.
- Machine guards, doors and access panels.
- Automated production and assembly equipment.
- Conveyors and material handling systems.
- Industrial control and signalling circuits.
- OEM machinery and automation systems.
