PC Series 4 Pin Threaded Cable Mount Electrical Connector
Built for cable-mounted connections where a secure threaded interface is required, this PC Series 4 Pin circular electrical plug combines a compact metal housing with solder-cup termination and a threaded coupling system. The design provides a firm mating connection while keeping the overall connector size suitable for compact electronic equipment and instrument assemblies.
The connector uses female copper contacts with gold plating to support stable electrical conductivity. Its aluminum alloy shell features a gold-oxide finish, while Bakelite/PBT insulation provides electrical separation around the contact system. With an IP66 ingress protection rating, the connector is suitable for equipment requiring enhanced protection against dust and water exposure.
Key Characteristics
-- 4-pin female-contact configuration for compact circuit connections
-- Threaded coupling helps maintain a secure mated connection
-- Cable-mount construction for direct integration with wiring assemblies
-- Compatible with 22–28 AWG cables
-- Gold-plated copper contacts for reliable electrical connection
-- Aluminum alloy shell with gold-oxide finish
-- Bakelite/PBT insulation structure
-- IP66 ingress protection for suitable equipment environments
-- Solder-cup termination for flexible wire connection
-- PC Series design compatible with corresponding PC-series connectors
Working Principle
During mating, the plug and corresponding socket are aligned and engaged through the threaded coupling mechanism. Tightening the threaded interface brings the contacts into their designed mating position and helps maintain mechanical stability during operation. The contact system then provides the conductive path between the connected circuits.
