ST DD420M0.1-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DD420M0.1-D1T ST D Series Safety Sensor?

The Pizzato ST DD420M0.1-D1T is a programmable RFID safety sensor designed for contactless monitoring of movable guards, access doors and protective devices on industrial machinery. As part of the advanced Pizzato ST D series, it combines RFID actuator recognition with two safety inputs, two safety outputs, a signalling output and an additional programming input for flexible integration into modern machine safety systems.

This model uses a high-level coded D1T RFID actuator, with individually coded actuators providing increased protection against manipulation and unauthorised substitution. Contactless sensing eliminates mechanical contact between the sensor and actuator, reducing wear during frequent guard operating cycles. When correctly integrated into a suitable safety architecture, ST D series sensors can support applications up to PL e, Category 4 and SIL 3.

The ST DD420M0.1-D1T operates from a 24 V DC supply and features a 0.1 m PVC cable with M12 connector on the right-hand side. The sensor provides two safety inputs IS1-IS2, two safety outputs OS1-OS2, one signalling output O3 and one programming input I3. Its D1T actuator provides a 12 mm actuation distance, while the technopolymer housing and IP67 / IP69K protection provide excellent durability in demanding industrial environments.

Programmable RFID Protection for Machine Guards

RFID safety sensors such as the Pizzato ST DD420M0.1-D1T monitor machine guards without requiring mechanical contact between the sensor and actuator. The high-level coded D1T actuator is electronically recognised by the sensor, helping protect against inappropriate actuator substitution while allowing a compatible safety control system to verify that a guard is correctly positioned before hazardous machine movement is permitted.

The ST DD420 configuration adds a dedicated I3 programming input alongside its two safety inputs, two safety outputs and signalling output, providing additional flexibility when configuring the safety function. Combined with the compact M12-connected design, robust environmental protection and coded RFID actuator, this makes the ST DD420M0.1-D1T a versatile choice for sophisticated machine safety installations.

Typical Applications

• Machine guard and access door monitoring.
