749374-3

D-Sub connectors are a type of electrical connector commonly used in computer and data communication fields. Model 749374-3 is one of the most popular D-sub connectors. It is widely used for audio-visual signals transfer and computer serial connections.

This model is usually composed of daughterboards, pin socket, and screws. The daughterboards have 9 pins in total that are shield anti-vibration type. It is made of phosphor bronze contacts with tin plating. The pin socket is plated with selective gold over nickel. The special mechanical construction design protects the components from external electromagnetic or mechanical stresses.

749374-3 connectors are mainly used in electronic devices, telecommunication equipment, electrical engineering equipment, and modem systems. With 9-pin configuration, these connectors can be applied for various data transfer purposes. The most popular connection types are RS-232 serial ports, video transfer, and audio output. Their robust connection and reliable contact points offer reliable connections by eliminating signal loss and providing better signal integrity.

These connectors provide a low-cost design and also deliver a reliable connection. The pin spacing in these connectors provides solderability and pliability in the connection process. The model 749374-3 is also much more durable than other D-sub connectors due to its stronger tension spring design and resilient insulation material.

The working principle of the 749374-3 is quite simple. When connecting two devices, the female side will be connected first. Then, the male side will be connected, and the screws will be tightened to secure that connection. The pin socket in the male part of the 749374-3 is generally secured with two screws. The screws are tightened to secure the connection between the two devices.

The 749374-3 D-sub connectors are widely applicable for data transfer in various fields due to its multiple pins, low cost, and robust connection. This type of connector provides better performance than other models in terms of signal integrity and operation stability. It is also much more reliable and easy to use than some of its counterparts.
