Rectangular Connectors - Headers, Receptacles, Female Sockets are commonly used in various PCE applications. One such type of connector is the DMC-M 20-22 PCE connector. This type of connector is designed to provide reliable electrical connections and is ideal for automotive, medical, military, test and measurement, and other harsh environments.

The DMC-M 20-22 PCE connector is a modular, two-piece board-to-board connector with a contact size of 20-22 AWG. This connector offers flexibility, enabling users to create custom solutions for any application. The terminal contacts are made of brass and plated with tin or gold for superior contact performance, and the insulator is made of UL 94V-0 polyester. It is capable of handling currents up to 2 amps with an operating temperature range from -40°C to +105°C. The contact is a standard 2.5 mm pitch, and the contacts are rated at 16-18 A.

One of the main advantages of the DMC-M 20-22 PCE connector is its audible retention by locking into place when mating, providing an additional level of security and ensuring both safety and reliable contact connection. This audible feature allows users to easily and safely make connections while working in cramped or dark conditions. The connector is designed to be dustproof and waterproof, and with a mating life of 500 cycles, it is ideal for applications where multiple connections and disconnections may be required.

The DMC-M 20-22 PCE connector is available in multiple contact configuration, such as 2-way through 70-way. It also offers multiple mating orientations, including horizontal, right angled and vertical, which makes it ideal for applications such as computer boards, medical instrumentation, industrial equipment, test and measurement, and automotive systems. The connector is also suitable for placement on both sides of the PCB, providing additional flexibility of use.

The working principle of the DMC-M 20-22 PCE connector is based on interlocking tactile pieces that fit securely together. The contact body of the connector is fitted with an insulated spring which moves in and out along the connector when connecting or disconnecting the connector. When mating the connector, the movable contact body engages on the contact sleeve and locks it into place, while at the same time the contacts are held securely in place in a contact cage.

The combination of the two pieces, the contact body and the contact sleeve, in the DMC-M 20-22 PCE connector allows for superior electrical contacts and a secure connection. It also has an audible retention feature so you can verify a successful connection and feel a tactile sensation when the connector is fully mated. This audible feature also ensures that the connector is not only secure but also highly durable, able to withstand vibrations, shocks, and other demanding applications.

In summary, the DMC-M 20-22 PCE connector is a versatile and reliable two-piece board-to-board connector with multiple contact configurations and mating orientations. Its audible retention feature allows for an easy and secure connection, and its superior electrical contacts, dustproof and waterproof characteristics, and 500 mating cycles make it ideal for many demanding applications.
