DCMD27H2PJK87

D-Sub Connectors

D-Sub connectors, also known as D-Subminiature connectors, are commonly used on electronic equipment for communication and signal connections. They are available in various sizes and variants and can be used for both data transmission and power applications.

The DCMD27H2PJK87 is a male/female connector of the D-Sub contact type; it is an IEC 60320 compliant power connector, typically used for power ratings up to 16A). It is available with various contact arrangements from 9 pins to 37 pins, and with optional keying are designed to prevent mismating. The contact material is copper alloy, plated with gold or tin, and it has an operating temperature range of between -55°C and +105°C.

Application Field

The DCMD27H2PJK87 is typically used for connecting devices such as PC peripherals and industrial electronics, including components used in medical, automotive, communication and instrumentation applications. It is suitable for both indoor and outdoor use, and is ideal for applications where a secure connection with reliable signal and power transmission is required.

Working Principle

The DCMD27H2PJK87 operates using the traditional pin and socket connection principle. It features two plastic shells, each containing the appropriate number of pre-inserted contact pins or sockets. To connect two cable harnesses, the contact pins on one cable are inserted into the corresponding sockets on the other, and the two shells are then mated and secured using a screw thread. The plastic-edge connector is designed to incorporate either through-hole or surface mount contacts.

To ensure a secure and reliable connection, the contact spring in each socket is designed to provide a high contact force as the cable harness is mated. This ensures that the contact pins have a secure and constant point of contact, and prevents the connector from being disconnected or loosening, even in harsh and demanding environments.
