PC Series Miniature Circular Electrical Connector PCB4TK
Product Information
The PCB4TK is a 4-position miniature circular electrical connector designed for reliable circuit connections in electronic instruments, control equipment, and compact electrical devices. Its straight plug configuration combines a lightweight aluminum alloy shell with a female solder-cup contact arrangement, providing a practical solution where compact size, secure connection, and environmental protection are required.
Key Characteristics
4 female contacts with a Φ1 mm contact diameter for compact circuit connection.
Push-pull fastening enables quick mating and disconnection without additional locking tools.
Aluminum alloy shell with anodizing treatment provides mechanical protection and surface durability.
Bakelite insulation helps maintain electrical isolation between contacts.
Gold or silver plated copper-alloy contacts provide stable electrical conductivity.
Available in golden yellow, pale yellow, and yellow-green finishes.
IP64 protection helps protect the mated connector against dust and water splashing.
Technology & Operating Principle
The connector transfers electrical signals or power through copper-alloy contacts secured inside an insulating Bakelite insert. The push-pull coupling structure allows the plug to engage and release efficiently while maintaining a stable connection during operation. The solder-cup termination supports direct wire soldering, making the connector suitable for equipment wiring and circuit interconnection.
