Why Choose the Carlo Gavazzi S.A.2 Magnetic Proximity Sensor?

The Carlo Gavazzi S.A.2 is a rectangular magnetic proximity sensor designed for reliable position and presence detection in industrial automation applications. Part of the Carlo Gavazzi S Series, it uses a magnetically operated reed contact within a compact plastic housing, providing simple non-contact switching without requiring a separate sensor power supply.

The S.A.2 features a normally open (NO) dry reed contact with a maximum switching voltage of 250 V AC, maximum switching current of 3 A and maximum switching power of 100 VA. Depending on the associated magnetic actuator and installation, the sensor supports switching distances up to 32 mm.

Its rectangular 79 × 21.2 × 11.5 mm plastic housing is side operated and incorporates mounting holes for straightforward installation. The S.A.2 is supplied with a fixed 0.5 m PVC cable and provides IP67 protection, making it suitable for demanding machinery, position-monitoring and industrial control applications.

Key Advantages

  • Magnetic proximity sensing provides reliable non-contact position detection.
  • Normally open reed contact provides straightforward switching without a separate electronic sensor supply.
  • Maximum switching distance up to 32 mm, depending on the associated magnet and installation.
  • 250 V AC maximum switching voltage supports a wide range of control applications.
  • 3 A maximum switching current provides substantial contact capability for a compact sensor.
  • 100 VA maximum switching power.
  • Fixed 0.5 m PVC cable simplifies field wiring.
  • IP67 protection supports use in demanding industrial environments.

Reliable Magnetic Position Detection for Industrial Machinery

Magnetic proximity sensors detect the presence of an external magnet without requiring mechanical contact between the sensing device and moving equipment. In the Carlo Gavazzi S.A.2, the magnetic field operates an internal dry reed contact, providing a simple and dependable normally open switching signal for industrial control circuits.

The absence of direct mechanical actuation makes the S.A.2 useful for position and end-of-travel detection where reducing mechanical wear is desirable. Its compact rectangular housing, IP67 construction and wide operating temperature range provide a robust sensing solution for machinery and automated equipment.

Typical Applications

  • Machine position and presence detection.
  • End-of-travel sensing.
  • Industrial doors, gates and access equipment.
  • Automated production machinery.
  • Material-handling systems.
  • Moving component position monitoring.
  • Industrial control and switching circuits.
  • Applications requiring non-contact magnetic actuation.
