ST DL311MK-E1T Pizzato ST D series safety sensor

Why Choose the Pizzato ST DL311MK-E1T ST D Series Safety Sensor?

The Pizzato ST DL311MK-E1T is a compact and robust RFID non-contact safety sensor designed for monitoring machine guards, access doors and protective devices in industrial automation systems. As part of the Pizzato ST D safety sensor series, it uses electronically coded RFID technology to provide reliable guard detection without mechanical contact, helping minimise wear in machinery with frequent operating cycles.

The ST D series combines redundant electronic safety architecture with two IS1–IS2 safety inputs, two OS1–OS2 safety outputs and one O3 signalling output. Operating from an industrial DC supply, the sensor is designed for integration into machine safety circuits and supports series connection with compatible safety devices for applications involving multiple monitored guards.

The ST DL311MK-E1T features an integrated stainless-steel M12 connector and a reinforced technopolymer housing with the connection positioned on the left. The E1T actuator configuration provides extended-range RFID sensing, while IP67 and IP69K protection and an operating temperature range of -25 °C to +70 °C make the sensor suitable for demanding industrial environments.

Reliable RFID Guard Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST D series monitor the position of movable guards and protective devices without requiring mechanical contact between the sensor and actuator. This contactless operating principle reduces mechanical wear compared with conventional electromechanical interlock switches and is particularly beneficial on machinery where access doors and guards are operated frequently.

The ST DL311MK-E1T combines RFID sensing with dedicated safety inputs, safety outputs and a separate signalling output, allowing integration into modern industrial safety and automation architectures. Its integrated M12 connection provides convenient installation and servicing, while the reinforced technopolymer housing and high ingress protection support dependable operation in challenging industrial environments.

Typical Applications

• Industrial machine guard and access-door monitoring.
• Packaging and production machinery.
• Automated assembly equipment.
• Robotic cells and industrial automation systems.
• Material handling and conveyor machinery.
• OEM machinery requiring non-contact RFID safety interlocking.
