Q:    What is an HDP20 connector?

A:     DEUTSCH HDP20 environmentally sealed connectors are designed for cable to cable applications. The HDP20 connectors are used in harsh environment applications where even a small degradation in connection may be critical.


Q:    What are the appropriate applications for HDP20 connectors?

A:     Truck, Bus, Off-highway, Construction, Agriculture, Mining, Emergency Vehicles, Forestry, Recreational, Marine, Motorcycle


Q:    When should I use HDP20 connectors?

A:     DEUTSCH HDP20 connectors provide reliability and performance on the engine or transmission, under the hood, for power control units, bulkheads, on the chassis, or in the cab. HDP20 connectors offer field proven reliability and rugged quality. The HDP20 design strengths include optional flange mounting, multi-pin arrangements, lower costs, and design flexibility. HDP20 connectors offer the designer the ability to use multiple size contacts within a single shell. Several accessories are available including backshells, strain relief, and dust caps.
