Allen-Bradley 440G-TZS21UPRH

Overview

The Allen-Bradley 440G-TZS21UPRH is a robust and reliable TLS-Z GD2 series guard locking switch engineered for rigorous safety demands in industrial environments. This essential safety component ensures enhanced personnel protection and controlled machine access by securely interlocking guards and doors, preventing entry into hazardous operational zones until safe conditions are met. Featuring a crucial power-to-release solenoid operation, the switch unlocks only when 24V AC/DC power is actively supplied, providing a critical layer of safety by maintaining a locked state during power loss situations. Its impressive 2000N (approximately 450 lbs) holding force guarantees a firm and uncompromised lock, even under significant pressure. The inclusion of a fully-flex actuator accommodates minor misalignments, offering versatile positioning and ensuring consistent, secure engagement in diverse industrial settings.

Designed for seamless integration into modern safety systems, the 440G-TZS21UPRH incorporates both PNP safety and auxiliary contacts. These contacts facilitate advanced safety monitoring, enabling clear communication of guard status to your control systems and ensuring compliance with stringent safety regulations across manufacturing, automation, and process industries. With an 8-Pin Micro (M12) connector, installation and connection are streamlined, further enhancing its appeal for critical safety applications where reliability and ease of use are paramount.

Key Features

• Power-to-Release Operation: This intelligent locking mechanism ensures the guard remains locked and secure during power outages, only disengaging when power is explicitly applied. This enhances operational safety and prevents unintended access.
• Universal Solenoid Voltage (24V AC/DC): Compatible with a wide range of industrial power supplies, simplifying integration into existing electrical infrastructures without additional conversion equipment.
• Fully-Flex Actuator for Versatile Application: The flexible actuator design tolerates slight misalignment, ensuring dependable locking and unlocking cycles in various mounting configurations and conditions.
• Superior Holding Force (2000N / 450 lbs): Provides an exceptionally strong and reliable lock, preventing unauthorized or accidental opening of safety guards under normal or even high-stress conditions.
• Advanced Safety & Auxiliary Contacts: Equipped with 2 x PNP (0.2A max.) safety outputs and 1 x PNP (0.2A max.) auxiliary output for precise lock status monitoring, offering comprehensive feedback to safety control systems.
• Simplified Connectivity (8-Pin Micro M12 Connector): Features a standard M12 quick-disconnect connector, facilitating rapid and secure electrical hook-up and reducing installation time and complexity.
• Rugged Industrial Design: Constructed to withstand the harsh demands of industrial environments, ensuring long-term durability and consistent performance in challenging conditions.
