Push-pull PCB4TPK 4 Pin Female Straight Plug with Cover Solder CupsРС4ТВ RS4TV

PC Series 4 Position Miniature Circular Electrical Connector

The PCB4TPK PC Series miniature circular electrical connector is a compact solution for reliable circuit connections in electronic instruments and equipment. Its small-size construction combines a lightweight aluminum alloy shell with a practical push-pull fastening design, helping simplify installation where available space is limited.

Designed as a 4-position straight plug with female contacts, this connector uses solder-cup termination for convenient wire connection and maintenance. The aluminum alloy shell is treated by anodizing to improve surface durability, while the connector structure provides IP64 protection for suitable equipment and enclosed applications.

Key Characteristics
