Allen-Bradley 440G-LZS21UPLA Guardmaster 440G-LZ RFID guard-locking safety switch
Allen-Bradley 440G-LZS21UPLA Guardmaster 440G-LZ RFID guard-locking safety switch
The Allen-Bradley 440G-LZS21UPLA is a specific ordering configuration in the Guardmaster 440G-LZ RFID guard-locking safety switch family. Industrial buyers searching for this exact manufacturer reference are often replacing an installed component, completing scheduled maintenance, or sourcing a spare for a machine that cannot tolerate an incorrect electrical or mechanical configuration. The full ordering designation matters: products within the same family may have different functions, controls, or connections.
This model is relevant to controlled access to guarded machine areas where monitored guard locking and a lock status indication are part of the safety design. In production environments, the choice of a replacement component is influenced by existing controls, the equipment drawings, and the behavior expected by technicians and operators. Matching only the manufacturer and product family is insufficient when the application depends on a particular set of terminals, operating logic, power rating, or physical connections.
Corwin Solutions helps purchasing teams request hard-to-source industrial automation and maintenance components by their complete manufacturer numbers. When requesting this item, include the full 440G-LZS21UPLA designation, desired quantity, required condition and destination. We can review the sourcing requirement and provide a quotation subject to availability and confirmation of the offered unit condition and specification.
Technical Details and Product Specifications
- Manufacturer: Allen-Bradley
- Manufacturer part number: 440G-LZS21UPLA
- Product family: Guardmaster 440G-LZ RFID guard-locking safety switch
- Actuator coding: Unique
- Auxiliary output indicates: lock status
- Lock operation: power to lock
- Connection: 3 m cable
- Solenoid supply: 24 V DC
- Two PNP safety outputs and one PNP auxiliary output
Typical Industrial Applications
This product may be used for controlled access to guarded machine areas where monitored guard locking and a lock status indication are part of the safety design in appropriate industrial equipment. It may be relevant to OEM machines, automated production lines, industrial electrical panels, maintenance spare-part programs and repair projects where the designated model is specified in a bill of materials. Suitability depends on the actual machine design and applicable technical documentation.
Replacement and Compatibility Notes
Confirm unique RFID coding, power to lock behavior, lock status indication, the 3 m cable connection, actuator compatibility and the required safety circuit design. Check the installed unit label and approved engineering documentation before purchasing. Do not assume a similarly named or differently coded version is interchangeable. Safety-related components must be selected, installed and validated by qualified personnel against the machine risk assessment and applicable standards.
Sourcing Considerations
For replacement sourcing, photographs of the original nameplate, the machine model, the required quantity and the delivery location are useful. Availability, revision, new or refurbished condition, warranty and lead time should be confirmed during quotation. This listing does not represent a guaranteed stock position or a promise of plug-and-play interchangeability.
