440G-LZ Guard-locking Interlock Switch

The Guardmaster 440G-LZ from Allen-Bradley is a solenoid interlock switch with a rated holding force of 1,300N, that can be used on partial body access guards. The hygienic design, IP69K rating and stainless steel parts enable this switch to be used in wash down applications in the food & beverage, pharmaceutical, and semiconductor industries.

When the switch locking bolt is extended into and detected by the actuator, two OSSD solid state outputs are enabled preventing the opening of the guard. The locking bolt will only attempt to extend when the correct actuator is detected. The 440G-LZ switch can be used as part of a guard locking safety system to achieve performance Level ’e’ according to EN/ISO 13849-1 and is certified by the TÜV as meeting EN/ISO 13849-1 performance level ’e’ for both position and lock monitoring.

The semiconductor OSSD safety outputs of the switch can be connected in series with other safety components that have OSSD solid-state outputs. Two bright LEDs positioned on the front corners of the housing enable 270° visual diagnostics. The switch also has an auxiliary output as well as a manual release.

Advanced algorithms and a bi-stable solenoid result in low energy use. Peak power only occurs when changing from unlocked to locked (or vice versa). The bi-stable drive uses minimal power and will not produce heat when either locked or unlocked. The functionality is configured to replicate a traditional power-to-release or power-to-lock device The RFID actuators can be selected as either standard or uniquely coded. The user can select the level of actuator coding according to the foreseeable risk of tampering in accordance with the requirements of EN/ISO 14119:2013.
