Q:    What is a Circular DIN connector?
A:     TE Connectivity’s Circular DIN environmentally sealed connectors are designed for cable to cable, cable to board, and cable to device applications. The Circular DIN connectors are used in harsh environment applications where even a small degradation in connection may be critical.

Q:    What are the appropriate applications for Circular DIN connectors?

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


Q:    When should I use Circular DIN connectors?
A:     Circular DIN connectors provide reliability and performance on the engine or transmission, under the hood, for motor controllers, solenoid interfaces, on the chassis, or in the cab. Circular DIN connectors offer field proven reliability and rugged quality. Circular DIN connectors meet the requirements of the DIN 72585/ISO 15170 standards. They feature a coupling ring for mating. The heavy-duty Circular DIN connectors are suitable for in-line, flange mount, or PCB applications.
