ESQT-144-03-H-Q-309

The ESQT-144-03-H-Q-309 is a rectangular connector from the range of Headers, Receptacles, and Female Sockets. This component is designed to be fixed to printed circuit boards and is capable of accepting an electrical male-fitted contact and securely interlocking. Its application is to connect two electrical circuits, with at least one of them being mounted within the board, and is most commonly used in data, communication, instrumentation, medical, automation, and building control applications.

The ESQT-144-03-H-Q-309 is made of a molded-plastic body, housing multiple gold-plated contacts which are enclosed within an insert. This insert is then pressed into the body to create a secure connection between the contacts. The housing is fitted with a keyed locking mechanism that ensures that the contacts are firmly mated and prevents them from separating once assembled. This locking system also ensures that the contacts are electrically connected to the board.

The working principle of the ESQT-144-03-H-Q-309 is simple and can be broken down into two stages; the mating and unmating process. During the mating process, the male-fitted contact is inserted into the female connector and the locking mechanism is engaged which securely locks the two together. The contacts then electrically connect the two electrical circuits. During the unmating process, the locking mechanism is disengaged and the male-fitted contact is removed from the female connector which effectively separates the electrical circuits. This process is easy to perform, allowing for quick and simple installation and removal.

In conclusion, the ESQT-144-03-H-Q-309 is a rectangular connector from the range of Headers, Receptacles, and Female Sockets. It is designed to be fixed to printed circuit boards and accept a male-fitted contact to create an electrical connection. The keyed locking mechanism ensures the connection is firmly fixed and provides electrical continuity. Its application is mainly in data, communication, instrumentation, medical, automation, and building control applications and its working principle is easy to understand and perform.
