Product Description P/N: 440N-Z21S16H
Description
The Allen-Bradley 440N-Z21S16H is a SensaGuard non-contact safety interlock switch designed for safeguarding access to machinery. It utilizes RFID-based proximity sensing with a plastic barrel actuator to detect guard doors without mechanical contact. This switch is widely used in industrial automation where reliable safety monitoring and tolerance to misalignment are critical.

Information About 440N-Z21S16H
The 440N-Z21S16H belongs to the Allen-Bradley Guardmaster SensaGuard series, engineered for robust and tamper-resistant safety applications. It operates at 24 V DC and features an 18 mm plastic cylindrical barrel sensor paired with an 18 mm plastic standard code actuator. The device offers a guaranteed sensing distance of 15 mm and includes LED diagnostics for quick door-status verification and troubleshooting. Rated to Safety Category 4 / PLe and SIL 3 functional safety standards, it ensures maximum safety integrity. The switch provides dual PNP safety outputs plus one PNP auxiliary output, with an IP69K rating for protection against dust and high-pressure washdowns. Connection is facilitated via a 6-inch pigtail with 8-pin Micro (M12) connector. Its rugged design makes it ideal for washdown, food processing, packaging, and other demanding industrial environments.
Key Features:
-
Sensing Technology: RFID-coded, non-contact detection with high tamper resistance.
-
Actuator & Housing: 18 mm plastic barrel sensor with matching standard-code actuator.
-
Sensing Distance: Assured 15 mm proximity detection.
-
Outputs: 2 × PNP safety outputs (max 0.2 A), plus 1 × PNP auxiliary output.
-
Safety Ratings: Category 4, PLe, and SIL 3 certified for machine safety.
-
Environmental Protection: IP69K, sealed against dust and high-pressure washdowns.
-
Diagnostics: LED indication for door status and troubleshooting.
-
Connectivity: 6-inch pigtail with 8-pin Micro (M12) connector for quick wiring.
The 440N-Z21S16H delivers the reliability, precision, and safety compliance required for critical industrial safety access control.
