Allen-Bradley 440N-Z21SS2H is a sensaguard rectangular non-contact safety interlock switch that detects guarded-door position using a non-contact coded actuator rather than a mechanical plunger. This listing identifies the specific manufacturer reference for industrial buyers comparing installed equipment, arranging maintenance replacements or preparing a sourcing request. The exact catalog number is important: nearby models in the same family can differ in ratings, connections, configuration or control requirements.
Used on machine access doors and guarded enclosures where switch alignment and reliable safety monitoring matter. In a maintenance situation, component selection affects equipment uptime and the reliability of the complete installation. Rather than assuming a similar-looking unit is equivalent, purchasers should record the model from the existing equipment and check its electrical or mechanical interface before committing to a replacement.
Corwin Solutions supports request-for-quote sourcing for this specific model and related industrial maintenance needs. Buyers can provide photos of the existing nameplate, system application, requested quantity and condition preferences to help distinguish revisions and identify a suitable source. This listing does not represent confirmed on-hand inventory or an offer for immediate shipment.
Technical Details and Product Specifications
Typical Industrial Applications
Used on machine access doors and guarded enclosures where switch alignment and reliable safety monitoring matter. Exact suitability depends on system design, equipment operating conditions and the manufacturer instructions for the chosen model.
Replacement and Compatibility Notes
Confirm actuator coding, mounting, wiring, safety controller interface and site-specific risk assessment. Before ordering, review mounting dimensions, accessory requirements, certifications and any changes needed to the control panel or machine commissioning procedure.
