Connector combines rapid termination technique with high mating cycle capability

04 March 2019

The new robust Han ES Press HMC (High Mating Cycles) connector series from HARTING combines can be installed quickly without tools and it able to handle at least 10,000 mating cycles.

The quick connect technology used in the Han ES Press HMC involves the contact inserts being equipped with a pre-tensioned cage clamp which is triggered by an actuator. If the actuator is pushed into the contact chamber, the cage clamp returns to its original position and secures the conductor end. To release the connection, requires just a screwdriver being pushed into the actuator and the lever moved to the transition to the insulating body. The spring then releases the end of the conductor once again – for de-installation or when replacing components, for example.

The suitability of the Han ES Press for a high number of mating cycles has been achieved by fitting the contact inserts in Han standard housing sizes 6 B to 24 B. The standard housings are already available in versions with locks and seals optimised for high mating cycles. Complementing this arrangement, the contacts and grounding elements are extremely resistant to abrasion due to a special surface coating.

The connector is able to withstand vibrations, which results from the tightness with which the conductor fits as a result of the constant pressure of the cage clamp. In addition, installation and connection times are reduced when compared to conventional cage clamps, screw connections or hard wiring techniques. On-site installation time is reduced, and the ability for rapid disconnection facilitates servicing.

The Han ES Press HMC is said to be particularly suitable for test & measurement applications where a test installation may often be hooked up to different power sources, such as portable machinery and devices.
