Omron PYC-A1 Relay Hold-Down Clip

Model Identifier PYC-A1
Official Part Number PYC-A1
GTIN Standard 4536853726171

Technical Overview

The Omron PYC-A1 is a robust metallic hold-down clip specifically engineered to secure Omron LY and MY series general-purpose relays into their corresponding square sockets, such as the PYF and PTF series. This retaining fastener provides critical mechanical stability in control panels, energy management systems, and industrial machinery, preventing relays from dislodging due to mechanical shock or high-frequency vibration.

Key Features

  • Designed specifically for square sockets including the PYF and PTF series.
  • Secures Omron LY and Super MY Series general purpose relays.
  • Mitigates relay loosening from mechanical shock and continuous vibration.
  • Manufactured as a heavy-duty metallic retention fitting for industrial control panels.
  • RoHS 3 Compliant and easily integrates into DIN rail or surface mount assemblies.

Industrial Applications

1. Industrial CNC Machining Centers

CNC routers and milling machines generate significant operational vibration and mechanical resonance that transfer directly to the electrical control cabinet.

Problem Solved

Secures MY/LY relays firmly in PYF/PTF sockets, preventing intermittent contact failure or control logic dropouts caused by vibration-induced unseating.

Vibration ToleranceControl CabinetRelay RetentionCNC Automation

2. Railway Signaling Enclosures

Trackside and rolling stock electrical panels are continuously subjected to immense shock and mechanical stress from passing trains.

Problem Solved

The metallic retention clip physically locks the relay into the DIN-rail mounted socket, ensuring critical safety signaling circuits remain closed despite violent mechanical shock.

3. Marine Engine Control Systems

Marine propulsion systems create persistent low-frequency vibrations that, over time, can walk standard plug-in relays out of their receptacles.

Problem Solved

Employs the 46mm mechanical retaining fastener to clamp the relay body securely against the socket face, guaranteeing uninterrupted power switching in rough seas.
