High-Voltage Sub-D Connectors: Reliable Performance at 13.5kV and 21km Altitude

Teledyne, a leading provider of advanced electronic solutions, has recently unveiled a new high-voltage connector system designed for use in demanding environments. This innovative system is capable of operating at voltages up to 13.5kV and altitudes of 70,000 feet (21km).

The connector system, known as DHM, features Teledyne's self-contained 'Hi/Mate' inserts, which are pre-wired inside sub-D housings and back-shells. These connectors are exclusively available as pre-assembled units, already attached to cables.

"The DHM inserts utilize Teledyne's advanced interface sealing system, making them suitable for a wide range of aerospace and defense electronic applications. Additionally, they are ideal for high voltage applications in industrial equipment, where exceptional HV performance and temperature resilience are essential," explained a spokesperson from the company.

The DHM connector system is available in various configurations, including two, three, five, and eight contact versions. The sub-D housings come in different lengths, allowing for flexibility in different applications. Furthermore, there are options to replace some of the contacts with multiple lower-voltage pins, providing even greater versatility.

Operating within a temperature range of -55 to +125°C, the DHM connectors can carry a current of up to 5.9A at 80°C in free air. For added convenience, rotating jack screws for latching can be included as an option. The plugs can also be equipped with back-shells, while the receptacles can be mounted on either the front or rear panel.
