Allen-Bradley 1492-EAJ35 DIN Rail End Anchor

The Allen‑Bradley 1492‑EAJ35, also cataloged as the 1492‑EAJ35 end anchor, operates as a mechanical rail‑retainer used to secure terminal‑block assemblies and prevent lateral movement along standard 35 mm DIN rails in industrial control cabinets.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

End anchors contribute to stable wiring assemblies by preventing terminal blocks from shifting under vibration. Mechanical stability helps maintain shield continuity and reduces noise coupling into Profinet and EtherNet/IP deterministic networks. Fixed positioning of terminal blocks also supports consistent conductor strain relief and minimizes transient disturbances on high‑speed industrial Ethernet cabling.

Frequently Asked Questions

Q: Does the anchor require tools for installation? A: It typically snaps or clamps onto the DIN rail; tightening hardware depends on the specific panel standard.

Q: Can it be used with mixed terminal‑block types? A: Yes. It secures any 35 mm DIN‑mounted terminal blocks regardless of tier or function.

Q: Does the anchor provide electrical grounding? A: No. It is a mechanical retainer and does not serve as a grounding component.

Field Installation Guidelines

• Mount the anchor at the end of a terminal‑block group to prevent lateral sliding.
• Ensure the DIN rail is properly bonded to the cabinet’s protective earth.
• Tighten any retaining screws to manufacturer torque recommendations to avoid loosening under vibration.
• Maintain clearance around the anchor to prevent interference with adjacent wiring ducts.
• Verify terminal‑block alignment after installation to ensure strain‑relief consistency.
