📝 Product Overview

The Allen-Bradley 440N-Z21SS2BN Guardmaster SensaGuard Safety Switch is an industrial machine safety device designed to monitor protective guards, access doors, and safety gates in automated machinery. Manufactured by Allen-Bradley, a brand of Rockwell Automation, the SensaGuard product family uses non-contact sensing technology to support reliable guard-position monitoring in industrial safety applications.

The Allen-Bradley 440N-Z21SS2BN is specified as a 24V DC safety switch with two PNP safety outputs and one PNP auxiliary output. The safety outputs can be integrated into a compatible safety relay or safety controller to monitor the status of a machine guard. The auxiliary output may be used for supplementary status indication or diagnostics, subject to the manufacturer’s wiring instructions. The safety function depends on the overall system architecture and must not rely solely on the auxiliary output.

This model is specified with a 10-metre fixed PVC cable, which can simplify wiring where the supplied cable length suits the installation. The cable must be routed and protected appropriately for the machine environment, considering abrasion, movement, chemical exposure, temperature, and other installation conditions.

For machine builders, maintenance teams, panel manufacturers, and system integrators, the Allen-Bradley 440N-Z21SS2BN provides an option for non-contact guard monitoring. Before ordering, verify the complete catalog number, output configuration, cable length, sensing distance, protection rating, and actuator compatibility. The supplied description indicates that a standard-coded RFID actuator is included; confirm this against the supplier’s package details.
