ST HD611N2-E1T Pizzato ST H series safety sensor

Why Choose the Pizzato ST HD611N2-E1T Safety Sensor?

The Pizzato ST HD611N2-E1T is a compact and reliable electronic RFID safety interlock sensor from the Pizzato ST H series, designed for monitoring movable guards, safety doors and access points on industrial machinery. Its RFID technology provides dependable guard position detection without mechanical switching contacts, making it suitable for modern machine safety and automation systems.

The ST H series combines coded RFID detection with a robust technopolymer housing for demanding industrial safety applications. The ST HD611N2-E1T features an integrated fixed PVC cable connection and a high-coded E1T actuator configuration. The E1T actuator is the larger ST H series actuator, providing an approximately 18 mm actuation distance and front fixing for flexible machine guarding installations.

With 24 V DC operation, two safety outputs and one auxiliary signalling output, the ST HD611N2-E1T provides straightforward integration with industrial safety control systems. Its high coding level means the sensor recognises the corresponding E1T actuator type, helping provide reliable guard monitoring in safety-critical machinery.

Reliable Safety Monitoring for Industrial Machinery

RFID safety sensors such as the Pizzato ST HD611N2-E1T monitor the position of machine guards without requiring mechanical electrical contacts between the sensor and actuator. When the correctly coded actuator is detected, the safety system can confirm the guard position and permit the protected machine function to operate.

The ST H series is designed for machine builders and industrial automation engineers requiring dependable guard monitoring and straightforward integration with safety control systems. High-level RFID coding helps reduce the risk of unauthorised actuator substitution, while the non-contact design avoids mechanical wear associated with conventional safety switches. The auxiliary signalling output can provide additional guard-status information to suitable control equipment.

Typical Applications

• Industrial machine safety doors and access guards.
• Automated production and processing machinery.
• Robotic cells and guarded automation equipment.
• Packaging and material handling systems.
• Manufacturing machinery requiring non-contact guard monitoring.
• OEM machine-building and industrial safety applications.
