Why Choose the Carlo Gavazzi SMS-A2P-02 Safety Magnetic Sensor?
The Carlo Gavazzi SMS-A2P-02, manufacturer part number SMSA2P02, is a cylindrical coded safety magnetic sensor designed for non-contact monitoring of hinged, sliding and removable machine guards. It provides 1 normally open and 1 normally closed contact and uses multiple-flux magnetic coding to operate with the corresponding coded actuator rather than an ordinary magnet.
The SMS-A2P-02 provides an operating distance of 15 ± 4 mm, a release distance of 20 ± 6 mm and a reset distance of 25 ± 7 mm. Its non-contact magnetic operating principle eliminates the need for mechanical actuation between the sensor and guard, helping reduce wear in machinery where doors and guards are operated frequently.
Designed for demanding industrial environments, the sensor features a cylindrical M18 × 1 housing, IP67 protection and a 2 m PVC cable. When correctly applied with the appropriate coded magnetic unit and safety circuitry, the SMS-A2P-02 is designed for applications up to Safety Category 4.

Coded Non-Contact Monitoring for Machine Guards
Safety magnetic sensors such as the Carlo Gavazzi SMS-A2P-02 monitor the position of machine guards without requiring direct mechanical contact. The sensor responds to its corresponding coded magnetic actuator when it enters the defined operating range, allowing the machine safety system to determine whether a hinged, sliding or removable guard is in the required position.
The SMS-A2P-02 uses multiple-flux coding and provides complementary 1NO + 1NC contacts. Combined with its IP67 cylindrical housing and non-contact operating principle, this makes it suitable for industrial machinery where dependable guard monitoring, resistance to harsh conditions and reduced mechanical wear are important.
Typical Applications
- Hinged machine guard monitoring.
- Sliding safety doors and guards.
- Removable machine guards and protective covers.
- Automated production machinery.
- Packaging and processing equipment.
- Machine tools and manufacturing systems.
- Industrial equipment exposed to dirty or damp conditions.
- OEM machine safety and guard-monitoring systems.
