Allen-Bradley 440N-Z21S26H

Overview

The Allen-Bradley 440N-Z21S26H is a Guardmaster RFID-coded non-contact safety switch offering high-level tamper resistance and reliable safety performance. It features 2 normally closed (N/C) safety outputs and 1 normally open (N/O) auxiliary output, with a high coding level to prevent actuator substitution. This switch uses a M12 quick-disconnect connector, supports 24V DC operation, and has an IP69K-rated housing, making it ideal for hygienic and washdown environments.

Key Features

  • Contact Configuration: 2 N/C (safety) + 1 N/O (auxiliary)

  • Coding Type: High-level RFID (prevents bypassing with generic actuators)

  • Actuation: Non-contact (coded actuator required, sold separately)

  • Voltage Supply: 24V DC

  • Connection Type: M12 8-pin quick-disconnect

  • Status Indicators: Integrated LEDs

  • Housing Rating: IP69K (washdown capable)

  • Housing Material: Durable plastic or stainless steel (model dependent)

  • Safety Category:

    • PLe (ISO 13849-1)

    • SIL 3 (IEC 61508)

    • Category 4 (EN ISO 13849-1)

Technical Specifications

  • Catalog Number: 440N-Z21S26H

  • Series: Guardmaster RFID Safety Switches

  • Switching Distance: Typical range of 10 mm (varies with actuator)

  • Max Current per Contact: 250 mA

  • Response Time: < 20 ms

  • Operating Temperature: -25°C to +70°C

  • Mounting: Flat surface mount

  • Certifications: UL, CE, cULus, TÜV, Ecolab

Applications

  • Food and beverage production lines

  • Pharmaceutical and hygienic automation equipment

  • High-security machine guarding

  • Washdown zones and harsh industrial areas

  • Tamper-resistant guard door interlocking

Why Choose the 440N-Z21S26H

  • High-coded RFID security prevents actuator spoofing

  • IP69K rating ensures maximum protection in wet environments

  • Compact and hygienic design ideal for sanitary applications

  • SIL 3 and PLe certified for top-tier functional safety compliance
