ST DL420N10-D1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL420N10-D1T ST D Series Safety Sensor?

The Pizzato ST DL420N10-D1T is a programmable RFID coded non-contact safety sensor with actuator designed for reliable monitoring of guards, doors and protective devices on industrial machinery. Part of the Pizzato ST D RFID Safety Sensor series, it combines electronic RFID actuator recognition with solid-state safety switching to provide dependable guard monitoring without the mechanical wear associated with conventional electromechanical safety switches.

The ST DL420N10-D1T provides two safety inputs IS1–IS2, two safety outputs OS1–OS2, one signalling output O3 and one programming input I3. This programmable 420 configuration offers flexible integration into modern machine safety architectures, while the safety inputs allow compatible devices to be incorporated into series-connected safety systems.

Operating from a 24 V DC supply, this version features an integrated 10 m PVC cable exiting from the left-hand side of the technopolymer housing. The supplied D1T high-coded RFID actuator provides a 12 mm actuation distance and measures 45 × 25 × 18 mm, with front and side fixing options. With IP67 / IP69K protection and an operating temperature range of -25 °C to +70 °C, the sensor is well suited to demanding industrial safety applications.

Key Advantages

• Non-contact RFID coded safety sensing reduces mechanical wear and maintenance requirements.
• D1T high-coded RFID actuator provides enhanced protection against actuator substitution and manipulation.

Reliable High-Coded RFID Guard Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST D series monitor movable guards without requiring physical contact between the sensor and actuator. When the correctly coded actuator enters the sensor's operating zone, the electronic safety outputs communicate the guard condition to the connected safety control system. The D1T high-coded actuator provides enhanced resistance to actuator substitution, making the sensor suitable for machinery where increased protection against manipulation is required.

The ST DL420N10-D1T combines high-coded RFID recognition with safety inputs, safety outputs, signalling and programmable functionality. Its integrated 10 m cable is particularly useful on larger machines where the sensing point is positioned some distance from the safety controller, while the sealed IP67 / IP69K construction supports reliable operation in dusty, wet and demanding industrial environments.

Typical Applications

• Machine guard and safety-door monitoring.
• Industrial production and assembly machinery.
• Packaging and processing equipment.
• Automated manufacturing cells and robotic systems.
• Conveyors and material handling equipment.
• Large machinery requiring extended cable reach and high-coded RFID guard monitoring.
