The flange connector is a square-flange bulkhead receptacle with a threaded coupling: contacts sit in a potted insulator behind a compression seal, and the line-side plug locks onto the coupling nut. It is the general-purpose building block for instrument housings that need a bolt-down penetration with a watertight, tool-tightened mate.
Product Highlights
- Bolt-down flange: square flange with 4 holes spreads the seal load and resists torque from the coupling nut.
- Threaded locking mate: the plug’s coarse thread gives a vibration-proof lock that push-pull connectors cannot match.
- Potted contact insert: the insulator is potted at the rear, so water has no wick path along the leads.
- Multi-contact in one unit: several circuits cross the wall through a single penetration.

Structure & Sealing
The receptacle sits through the housing hole; the flange is bolted down and compresses the O-ring beneath it. Contacts are carried in a potted insert and exit as sleeved pigtails. The plug mates onto the spigot and locks with the external thread — tightening the ring also loads the face seal.
Applications

Packaging & Delivery
Each connector is shipped in an ESD-safe bag with a protective cap on the mating face, packed in a foam-lined carton. Lead time depends on configuration and quantity — contact us for a current schedule. DHL / FedEx / air / sea freight supported.
FAQ
Can the flange be adapted to my hole pattern?
Yes — send the drawing and we will machine to match.
Is the mating plug included?
Plug and receptacle are available separately or as a matched set.
What torque is used on the coupling?
Hand-tight plus a firm finish is normally sufficient; torque values are in the datasheet.
How are the pigtails marked?
Leads are sleeved and numbered at the factory.
