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.

Specifications

Applications & Advantages
