Datasheet

HARTING has added a range of new fixing elements to extend the flexibility of the D20 full metal housings used with the company’s DIN 41612 connector family. In developing the HARTING D20 full metal housing for DIN 41612 connectors, the company has concentrated on flexibility and handling convenience. For example, where components are installed in difficult-to-reach or confined spaces, internal hexagonal screws are used as fixing elements for the D20 housing to ensure that they can be screwed in easily. Even if the angle is less than 25°, a ball-head screwdriver can still be used.

These new fixing elements not only extend the range of housings available they also offer further locking options. The new fixing elements create a robust mechanical connection thanks to their established screwing technology combined with a recently developed alternative screwless locking option. The D20 full metal housings can be secured manually with an audible click – no additional tool is needed. This makes locking and unlocking more convenient and faster.

The locking levers simplify operation significantly, and can also be used to aid insertion or removal of daughter cards in a 19-inch rack. When a large number of tightly packed daughter cards are used, this easily accessible removal aid is a great help because less force is needed.

The permanent electrical connection provided by the fixing element ensures that the housing and the racking system are always in contact, giving enhanced screening properties with attenuation of over 30 dB via the D20 housing.

The robust and vibration-proof D20 housing range is the system of choice for railway applications. The new fixing element is designed to be vibration-proof, and the plastic used for the ejection lever has the fire classification and smoke index suitable for railway applications: I2/F1 under NFF 16-101.
