Q:    What is a DTM connector?

A:     DEUTSCH DTM environmentally sealed connectors are designed for cable to cable, cable to board, and cable to device applications . DTM connectors are used in harsh environment applications where even a small degradation in connection may be critical.


Q:    What are the appropriate applications for DTM connectors?

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


Q:    When should I use DTM connectors?

A:     DEUTSCH DTM connectors provide reliability and performance on the engine or transmission, under the hood, on motor controllers, solenoid interfaces, on the chassis, or in the cab. DTM connectors offer field proven reliability and rugged quality. The DTM design strengths include optional flange mounting, multi-pin arrangements, lower costs, and design flexibility. DTM connectors offer the designer the ability to use multiple size 20 contacts, each with 7.5 amp continuous capacity, within a single shell.
