by Allen-Bradley

OverviewEnhance the safety protocols of your industrial operations with the Allen-Bradley 440K-T11147 Trojan 5 Tongue Switch. This advanced safety interlock device is expertly engineered to prevent unwanted entry into hazardous machine zones while equipment is active. A key component for dependable safety systems, the 440K-T11147 integrates effortlessly into diverse industrial settings, safeguarding both personnel and valuable assets. Featuring a resilient GD2-style metallic head, this Trojan 5 series switch can withstand the demands of rigorous applications. It incorporates two normally closed (N.C.) safety contacts, essential for immediate and secure circuit interruption, along with one normally open (N.O.) auxiliary contact for critical status monitoring. Its crucial break-before-make (BBM) contact sequencing further boosts safety by preventing any temporary overlap during transitions, ensuring precise management. Please note this unit requires a separate actuator, allowing for flexible, application-specific setups, and includes a standard M20 conduit entry for simple integration into existing wiring.Key Features Trojan 5 Series Reliability: A dependable component within the acclaimed Trojan 5 series, celebrated for consistent performance and safety adherence in vital industrial environments. Robust GD2-Style Metal Head: Constructed to endure harsh industrial conditions, its metal head provides exceptional durability and protection against impacts and environmental elements. Dual N.C. Safety Contacts: Equipped with two normally closed safety contacts, this switch ensures a secure and immediate break in the safety circuit, elevating operational security. Single N.O. Auxiliary Contact: The inclusion of one normally open auxiliary contact enables efficient status monitoring and integration with other control functions, offering enhanced system visibility. Break-Before-Make (BBM) Contact Timing: Guarantees circuit disconnection before a new connection forms, preventing hazardous momentary overlaps and ensuring accurate control. Flexible Actuator Integration: Designed without an included actuator, this switch permits selection of a specific tongue actuator tailored to your unique application needs. Standard M20 Conduit Entry: Features a widely compatible M20 conduit entry, facilitating easy and secure connection to standard industrial wiring for a streamlined installation process.

It ensures that dangerous machinery cannot operate if the guard is open, by means of an actuator, often called a "tongue," that is inserted into the switch when the guard is closed.Is the actuator included with the 440K-T11147?No, the actuator for the 440K-T11147 is not included and must be purchased separately. This allows for greater flexibility in selecting the appropriate actuator for specific application requirements.What does "Break-Before-Make" contact timing mean?Break-Before-Make (BBM) contact timing ensures that the breaking of a circuit occurs before a new connection is established. This is a critical safety feature that prevents any momentary overlap between electrical contacts, thereby eliminating potential hazards such as short circuits or unintended machine movements.
