Multi-pin connectors are versatile components used for various applications in electronics and electrical systems. They allow multiple wires or cables to be connected together securely. Here are some common types of multi-pin connectors:

1. Circular Connectors: These connectors are typically used for data transfer, electrical signal transmissions, or powering electrical devices. Some circular connectors can carry both power and signal simultaneously.

2. Industrial Multi-Wire Connectors: These provide a fast and easy way to make electrical connections in machines or systems. They consist of components like housings, connector inserts, conductor terminations, and fittings.

3. Ceramaseal® Multipin Connectors: These feedthroughs have two or more conducting pins and are designed for use in vacuum environments. They accept plugs on the air side and, in some cases, on the vacuum side as well.
