ST GD510N4-E1T Pizzato ST G series safety sensor

Why Choose the Pizzato ST GD510N4-E1T Safety Sensor?

The Pizzato ST GD510N4-E1T is a compact and highly reliable RFID non-contact safety sensor designed for monitoring movable guards, safety doors and protective access points on industrial machinery. As part of the advanced Pizzato ST G RFID Safety Sensor Series, it combines high-level RFID actuator coding with redundant electronic safety technology for dependable machine interlocking without mechanical contact.

The ST GD510N4-E1T provides 2 safety inputs (IS1–IS2), 2 safety outputs (OS1–OS2), 1 signalling output (O3) and an EDM feedback input. This configuration supports integration with safety relays, safety PLCs and external switching devices, while the EDM function enables monitoring of downstream contactors or relays controlled by the safety outputs.

Operating from a 24 V DC supply, this cable-connected version is paired with the SM E1T high-level coded RFID actuator, providing an actuation distance of approximately 18 mm. Its robust IP67 / IP69K protection and operating temperature range of -25°C to +70°C make it suitable for demanding industrial environments where dependable guard monitoring is essential.

Key Advantages

• Non-contact RFID safety interlock technology minimises mechanical wear.
• High-level individually coded RFID actuator provides enhanced protection against interlock bypass.
• Extended approximately 18 mm actuation distance with the E1T actuator.

Reliable RFID Guard Monitoring for Industrial Automation

RFID safety sensors such as the Pizzato ST GD510N4-E1T monitor the position of movable machine guards without requiring physical contact between the sensor and actuator. When the high-level coded actuator leaves the permitted sensing area, the electronic safety outputs change state so the connected safety system can stop or prevent hazardous machine movement.

The ST G series uses redundant electronics and can be integrated with safety modules or safety PLCs equipped with OSSD inputs. The ST GD510N4-E1T additionally provides safety inputs for safety-chain integration and an EDM input for monitoring external switching devices, while its high-level coded E1T actuator and extended sensing distance provide flexible installation on industrial guards and access points.

Typical Applications

• Industrial machine guard monitoring.
• Safety doors and protective access panels.
• Automated production and assembly lines.
• Robotic cells and safety enclosures.
• Packaging and processing machinery.
• Food and pharmaceutical production equipment.
• CNC machines and manufacturing equipment.
• OEM machinery and industrial automation systems.
