DBMQ21H1P0L4A191

D-Sub Connectors are used in various kinds of electronic devices as it not only provides good electrical conductivity but also can adapt to high and low working temperatures. Most D-Subs contain two parts which are male and female connectors. The male connector has protruding pins while the female connector consists of sockets which serve as the connection point for the pins. DBMQ21H1P0L4A191 is one type of D-Sub connectors.

DBMQ21H1P0L4A191 is a type of high quality sub-miniature D-Sub which was developed based on the telecommunications applications and signal transmission in harsh environmental conditions. This D-Sub has two parts, a male side with 15 pins and a female side with 9 sockets. It comes with an overall dimension of approximately 33mm and a pin size of 0.5mm in diameter. The terminal pitch of DBMQ21H1P0L4A191 is 2.54mm.

DBMQ21H1P0L4A191 is especially designed for the purpose of radio frequency connections in the form of antennae cable designs. As mentioned before, the pin and socket contacts are 0.5mm in diameter which allows for a bigger contact area. Therefore, the connection with wires is more stable and less prone to having its signals interrupted. Other than that, the gold plated used on the terminals prevents corrosion from occurring and providing good electrical conductivity. This D-Sub can function reliably in temperatures ranging from -40°C to +85°C and has a rated voltage of 100V to 300V.

In terms of its application fields, DBMQ21H1P0L4A191 is commonly used in the automotive, defense, medical, telecommunication, and power distribution industries. Its suited for high-speed data applications which require strong dB insertion loss performance and low impedance changes. Some of the examples of its uses are in audio equipment, car speakers, GPS system, touchscreens, oil industry, ON/OFF systems and so on.

To sum up, DBMQ21H1P0L4A191 is a type of D-Sub connector which is designed for signal transfer in tough environments with temperatures ranging from -40°C to +85°C. Its use of gold plated connection points offers good electrical conductivity and prevent corrosion. It can be used in various industries including automotive, defense, medical, telecommunication and so on where strong dB insertion loss performance and low impedance is required.
