Why Choose the Carlo Gavazzi SA2 Rectangular Magnetic Sensor?
The Carlo Gavazzi SA2 is a compact and reliable rectangular magnetic proximity sensor designed for non-contact position and presence detection in industrial automation systems. As part of the Carlo Gavazzi S series, it uses a normally open reed contact that switches when a suitable magnetic actuator enters the sensor's operating range.
The SA2 features a durable plastic rectangular housing with side operation and two mounting holes for straightforward installation. Its passive reed-switch principle requires no separate sensor power supply, making it a simple and dependable solution for monitoring doors, guards, machine components and other magnetically actuated mechanisms.
With a maximum switching distance of 32 mm, maximum contact switching voltage of 250 V AC, switching current up to 3 A and switching power up to 100 VA, the SA2 provides substantial switching capability in a compact sensor. A 0.5 m PVC cable and IP67 enclosure protection support reliable integration into demanding industrial environments.

Reliable Magnetic Proximity Detection for Industrial Machinery
Magnetic proximity sensors such as the Carlo Gavazzi SA2 detect the presence of a magnetic actuator without requiring physical contact between the sensor and moving component. The reed contact changes state when the magnet reaches the required operating position, providing a simple electrical signal for machine-control, indication or monitoring circuits.
The SA2's sealed rectangular construction, wide operating temperature range and IP67 protection make it well suited to industrial installations where reliable non-contact switching is required. Its compact housing and mounting holes allow convenient positioning alongside moving machine parts, doors and other magnetically actuated mechanisms.
Typical Applications
- Machine position and presence detection.
- Industrial door and access monitoring.
- Guard and enclosure position sensing.
- Conveyor and material handling equipment.
- Automated production machinery.
- Magnetically actuated switching systems.
