Why Choose the Pizzato ST HE310N3-H1TF Safety Sensor?
The Pizzato ST HE310N3-H1TF is a robust RFID non-contact safety sensor with magnetic actuator holding designed for monitoring guards, doors and access points on industrial machinery. As part of the advanced Pizzato ST H series RFID safety sensors, it combines high-level RFID actuator coding with electronic safety outputs and a permanent magnet to provide dependable guard detection and holding without mechanical contact.
This sensor incorporates two safety inputs IS1–IS2, two safety outputs OS1–OS2 and one signalling output O3, enabling integration into safety circuits and series-connected machine guarding systems. RFID technology provides reliable actuator recognition, while the high coding level helps protect against manipulation and unauthorised substitution of the associated actuator.
The ST HE310N3-H1TF operates from a 24 V DC supply and uses a fixed 3 m cable for straightforward machine wiring. Its integrated permanent magnet provides approximately 40 N holding force, helping keep lightweight guards closed against vibration, recoil and air turbulence. The symmetrical technopolymer housing, IP67 / IP69K protection and compact ST H format make it suitable for demanding industrial automation environments.

Reliable Safety Monitoring for Industrial Automation
RFID safety sensors such as the Pizzato ST HE310N3-H1TF monitor the position of movable machine guards without requiring mechanical contact between the sensor and actuator. When the correctly coded actuator is detected, the electronic safety outputs can signal the machine safety system that the guard is in the required safe position.
The ST H series adds magnetic holding to Pizzato's RFID sensing technology. The permanent magnet helps retain the actuator when a guard is closed, reducing unwanted opening caused by vibration, recoil or air movement. Series-connectable safety inputs and outputs make the sensor particularly useful in automated production lines, robot cells and machinery incorporating multiple guarded access points.
Typical Applications
- Machine guard and safety-door monitoring.
- Automated production and assembly machinery.
- Robot cells and robotic manufacturing systems.
- Packaging and processing equipment.
- Machining centres and industrial machine tools.
- Conveyors and material handling systems.
