Product Description

['Home', 'Allen-Bradley', 'Guardmaster Safety Switches', '440N-Z21SS2BN'] Need Allen-Bradley 440N-Z21SS2BN? Non-contact RFID safety switch for Machine safety / guarding systems. Supplied with full traceability and documentation.... Price & Availability Classified as a non-contact rfid safety switch, it is positioned as a direct replacement and service part for existing installations. It is intended for use within Machine safety / guarding systems, where dependable operation and a precise fit are essential to keeping the plant running. Listed as Active, it is offered as a maintained and verified spare that supports the continued operation of the installed base. Key technical specifications include: The Supply voltage is 24 V DC. Its Sensing technology is rated at RFID non-contact. For reference, the Cable length is 10 m. The Protection rating is IP69K. Its Actuator is rated at Included (coded). Notable features of this unit: RFID non-contact sensing technology. 24 V DC supply voltage. Supplied with 10 m prewired cable. IP69K protection for wash-down environments. Typical applications include Machine guard door interlocking, Hinge, sliding and lift-off guard monitoring, Wash-down and food-industry safety. It is compatible with or cross-references Allen-Bradley safety relays (e.g., MSR series), Light curtains and E-stops, Machine guard doors and brackets. The 440N-Z21SS2BN is the 10 m cable variant with coded actuator; the 440N-Z21SS2HN (see id 1052) differs in sensing distance/cable details. Confirm the exact suffix with the supplier. Within industrial automation and process-control environments, components of this type are relied upon to keep critical equipment operating safely and efficiently. They are typically specified where uptime, repeatability and a predictable maintenance cycle matter more than upfront cost. A non-contact rfid safety switch such as this one forms part of a larger machine or system, so correct identification and fitment directly affect the performance and safety of the whole installation. Allen-Bradley parts are widely used across power generation, manufacturing, oil and gas, water and process industries, where engineering teams standardise on proven series to simplify spares planning. When selecting a replacement, confirm the exact model designation and verify that the mechanical and electrical interface matches the unit currently installed. Cross-checking the order code, mounting style and connection type against the existing device helps avoid compatibility issues and unplanned downtime during a maintenance window. Where several variants exist, the suffix often defines voltage, range or firmware, so it should be matched precisely rather than approximated.
