ADDITIONAL DESCRIPTION Product DetailsAllen Bradley Guardmaster 440G-T27123 TLS-1-GD2 Solenoid Interlock SwitchExperience optimal machine safety guard security and operator protection with the 440G-T27123 TLS-1-GD2 Solenoid Safety Switch by Allen Bradley Guardmaster. This switch has 2 entry slots on the head, which can also be easily rotated to allow 4 actuator entry points. A blanking plug is provided to seal the unused slot.This unit is a positive mode, tongue-operated interlock switch that ensures guards are safely locked while the power supply to the machine is on. The barrier can only open when the internal solenoid is energised by an external signal. In addition, the power supply is isolated when the guard is released. This helps to prevent the risk of personnel entering a hazardous area where serious injury may occur. This versatile guard-locking safety switch is ideal for use with machines which do not stop instantly, or which may be damaged by interference while in motion.The 440G-T27123 switch has Power-to-Release functionality, M20 conduit entry, 2NC safety contacts and 1 NO auxiliary contact. The solenoid contacts are 1NC/1NO and the voltage is 230 V ac/dc. It has a high holding force of 2000N (450lbs), ensuring greater stability and security of the safety guard. This versatile unit is ideally suited for use in wet environments where machinery is regularly washed down as it is sealed to IP67. The housing material is made of UL approved glass-filled PBT, which ensures improved durability. The TLS-1-GD2 has an operating temperature of -20°C to +60°C (-4°F to +140°F). The rated insulation voltage is 500V and it has a thermal current of 10A. It is suitable for use with PLCs.Note: Actuator is not supplied and must be ordered separately.Warning: With the “power to lock” function, provisions are required to ensure that a dangerous situation cannot result from open circuit faults or power cuts. Features and Benefits:Convenient rotatable head with four possible actuator entry pointsThree manual release points with security screws allow release in emergenciesStainless-steel actuator guide fitted to protect the unit from actuator damage due to poor guard alignment or wearSuitable for use with PLCsBlanking plug allows the unused slot to be sealedFive contacts: 2NC/1NO for door position monitoring, 1NC/ 1NO for lock monitoringIP67 rated, ensuring no ingress of dust particles and durable against temporary immersion in water Certifications:EN954-1ISO13849-1IEC/EN60204-1NFPA79EN1088ISO14119IEC/ EN60947-5-1ANSI B11.19, AS4024CE certifiedUL approvedcULus approvedTUV certifiedCCC certifiedRockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach. What are Solenoid Interlock Switches?A solenoid interlock switch is a type of safety switch with an internal solenoid; a wire coil which converts electrical energy to mechanical. This type of mechanism limits access to dangerous areas where machinery may be functioning by ensuring that that barriers remain securely shut. The safety guard can only be opened through either energising (Power to Release) or de-energising (Power to Lock) the solenoid with an external signal. They are often used in industrial environments, for example with high inertia rotating machines.
