D-Sub connectors, such as the 748440-2, are used normally used to connect compute devices to peripherals. This particular model is ideal for sensor technology applications due to its robust design, providing reliable long-term operation in environments where dust, moisture and vibration may be common.

The 748440-2 is a two-piece, 10-contact D-Sub connection, constructed with tin-plated, outside-locking shells and including nickel-plated phosphor bronze contacts featuring gold-plated, crimp tails. Each contact is sealed with a Silicon O-ring fitted to the contact shell, ensuring dust and moisture protection. It is rated to 1 A at 250 VAC and has a working temperature range of -55˚C to +125˚C.

This connector makes use of the contact\'s three-part design. This design includes an insulated contact body, a metal contact pin and a metal crimp. The contact body is where the connection is made between the contact pin and the crimp. When the contact body mates with the contact pin, a pair of metal wipers slide along the surface of the insulated body providing extra contact protection.

This D-Sub connector utilizes a bayonet locking system meaning the two halves of the connector are securely fastened by turning the external locknut. This system contributes to the unit\'s excellent reliability and high mating cycle numbers. In order to ensure a reliable connection, each contact is securely locked against the connector body with a silicone back-up ring.

The 748440-2 is available in either male or female variants, making it an ideal connector for connecting two pieces of standard computer equipment. Thanks to its relative ease of installation and excellent contact protection, the 748440-2 offers reliable long-term operation even in the most challenging of environments.
