Door Pin Latches

Door pin latches use a spring-loaded pin mechanism that engages a receiver hole in the cabinet frame — providing positive, vibration-resistant engagement that resists rattle and accidental release on mobile equipment, specialized vehicles, and vibration-prone industrial enclosures. HTAN’s door pin latch range is manufactured with ISO 9001-certified quality and full OEM/ODM customization for global customers.

Key Features

  • Positive pin engagement: Mechanical pin-in-hole lock resists vibration-induced rattle and self-opening.
  • Spring-loaded snap-in: Automatic engagement on door closure — no separate locking action required.
  • High vibration resistance: Pin engagement remains positive under road vibration, machinery shock, and high-frequency oscillation.
  • Simple installation: Requires only a drilled hole in the frame — no keeper plate, no complex alignment.

Key Applications

  • Specialist & Modified Vehicles: Access panels on emergency vehicles, utility trucks, and military vehicles.
  • Rail Transit Compartments: Maintenance access panel latches on rolling stock subject to continuous vibration.
  • Industrial Machinery: Guard door latches on equipment subject to operational vibration from motors and cutting tools.

Frequently Asked Questions

What pin diameter is available?

Standard pin diameters are 6mm, 8mm, 10mm, and 12mm. Pin length, spring force, and release mechanism are configurable for OEM applications.

Can door pin latches be locked to prevent release?

Yes. Locking pin latch variants restrict the pin release via an integrated key cylinder or padlock provision — preventing unauthorized panel access.

How does a door pin latch differ from a cam latch?

A door pin latch provides a linear pin-into-hole engagement — best for high-vibration applications where a rotating cam could back off. A cam latch is better suited for frequent, easy access with tool-key operation on stationary enclosures.
