440G-LZ Guardmaster Guard Locking Switch

PublishTime：2022-05-19

This Guardmaster® 440G-LZ guard lock safety switch functions by extending a locking bolt from the switch through a hole in the actuator, which prohibits the opening of a guard.
The locking bolt drive mechanism and logic confirm that the locking bolt is allowed to extend only when the corresponding actuator is detected within range.
RFID technology enables high precision operation while meeting the requirements to prohibit actuator substitution as described in EN ISO 14119. The 440G-LZ safety switches are classified according to ISO 14119 as Type 4 interlocking devices with guard locking. The unique coded actuators are classified as having a high level of coding.
The Guardmaster 440G-LZ guard lock safety switch features OSSD outputs. These outputs are enabled only when the locking bolt is sensed in its extended position in the actuator. This action only happens when the guard is both closed and locked.
The locking bolt drive mechanism uses a bi-stable solenoid. As a result, the switch consumes little electrical power, with peak currents occurring (only briefly) on startup and after each movement of the locking bolt.
Because of its bi-stable drive, not only does the device consume minimal power, but it also does not produce heat while it is locked or unlocked.
Despite the bi-stable design of the locking bolt drive, the device logic and functionality are configured to replicate the functionality of a Power to Release or Power to Lock solenoid-operated switch (depending on type).
