Why Choose the Carlo Gavazzi FSQA2HFEX ATEX Magnetic Proximity Sensor?

The Carlo Gavazzi FSQA2HFEX is a robust ATEX-certified magnetic proximity sensor designed for non-contact position detection in potentially explosive industrial environments. Part of the Carlo Gavazzi FSQ Series, it combines encapsulated magnetic reed-switch technology with a rugged cylindrical AISI 303 stainless-steel housing.

The FSQA2HFEX provides a normally open (NO) contact and is designed for operation with suitable magnetic actuators. The FSQ series has an external diameter of approximately 16 mm, while the sensor uses a PG13.5 threaded housing. Depending on the selected Carlo Gavazzi magnetic actuator, the specified operating distance is 8–30 mm.

Designed specifically for hazardous-area applications, the FSQA2HFEX carries ATEX certification for Category 2G and 2D environments and has a T5 temperature class. Its contact is rated up to 250 V AC, 3 A and 100 VA, while a factory-fitted 2 m halogen-free PUR cable, IP66 protection and an operating temperature range of -20 to +60 °C support dependable installation in demanding industrial environments.

Reliable Magnetic Detection for Hazardous Areas

The Carlo Gavazzi FSQA2HFEX is designed for applications where conventional industrial sensors may not be appropriate because of a potentially explosive atmosphere. Its ATEX-rated construction, encapsulated sensing technology and stainless-steel housing make it suitable for non-contact monitoring of machine position, doors, covers and moving equipment in hazardous industrial environments.

Magnetic sensing eliminates the need for physical contact between the sensor and actuator, helping minimise mechanical wear in repetitive applications. With a normally open contact, operating distances up to 30 mm with the appropriate magnetic unit and a robust 2 m PUR cable, the FSQA2HFEX provides a practical solution for hazardous-area automation and position monitoring.

Typical Applications

• Position detection in potentially explosive environments.
• Hazardous-area industrial machinery.
• Machine door, cover and hatch monitoring.
• Actuator and equipment position sensing.
• Chemical and process-industry machinery.
• Industrial material-handling systems.
• Automated processing and production equipment.
• ATEX-rated industrial automation systems.
