ST DD421N10-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD421N10-E1T ST D Series Safety Sensor?

The Pizzato ST DD421N10-E1T is a non-contact RFID safety sensor with high-coded actuator designed for monitoring protective guards, access doors and other safety devices on industrial machinery. Part of the Pizzato ST D series, it uses RFID coded non-contact switching to provide dependable guard position detection without mechanical contact between the sensor and actuator.

The ST DD421N10-E1T is supplied with an E1T high-coded RFID actuator providing a 20 mm actuation distance. The actuator measures 40 × 50 × 16 mm and is designed for front fixing, providing generous operating tolerance for machine guard alignment while its high coding level helps protect against inappropriate actuator substitution or manipulation.

The sensor operates from a 10–30 V DC supply and provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. This configuration uses a PVC connection cable, while its right-hand connection orientation, technopolymer housing, -25 °C to +70 °C operating temperature range and IP67 / IP69K protection make it suitable for demanding industrial machinery and automation environments.

Reliable RFID Safety Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST D series monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. The high-coded E1T RFID actuator is recognised electronically, allowing a compatible machine safety system to determine whether the associated protective guard is correctly positioned before hazardous machine functions are permitted.

The 20 mm actuation distance provides generous installation tolerance, while high-level actuator coding improves resistance to inappropriate substitution or manipulation. Combined with comprehensive safety I/O, robust technopolymer construction and high environmental protection, the ST DD421N10-E1T provides a dependable guard monitoring solution for modern industrial automation systems.
