Connector system targets in-car applications

October 18, 2016 // By Christoph Hammerschmidt
ERNI Electronics is expanding its product range of compact and reliable connectors. The new MicroBridge product family with 1.27 mm pitch has been designed specifically with the requirements of customers in the automotive industry in mind.

The cable-to-board connectors have been developed on the basis of the LV214 and USCAR automotive test specifications. The MicroBridge variants satisfy the requirements of the automotive industry, particularly in terms of mating reliability. Koshiri security and an electrical, optional CPA (connector position assurance) also go to ensure a reliable and robust connection. Despite the compact 1.27 mm pitch, MicroBridge is extremely robust and withstands the vibrations in vehicles thanks to double-sided interlocking. The compact design is perfect for use in compact installation spaces.

The MicroBridge female connectors will be available with IDC and crimp terminations. The modular family comprises single and two-row versions with 2 to 40 pins. The single-row IDC female connector is available with a 90° and 180° cable outlet, the two-row version with a 180° cable outlet. The male connector designed for SMT is available as both a straight and angled version as well as single and two-row versions. Thanks to their modular design, female connectors can be mated with their male counterparts having the same number of pins irrespective of the termination technique (IDC or crimp). The crimp contacts in the female connector housing feature primary and secondary interlocking, whereas with the IDC versions, the contacts are already assembled in the housing. The new closed crimp contact ensures enhanced reliability during processing. Thanks to the dual IDC termination and an additional strain relief, the MicroBridge is ideal for meeting the exacting requirements posed by the harsh environments encountered in the automotive industry. The colour and mechanical coding optionally available for every number of pins facilitates assignment and prevents improper mating.

The high temperature resistance of up to 150°C allows the connectors to be used in areas exposed to demanding temperature conditions, e.g. close to LEDs in the headlights. The current rating is specified according to the number of pins and the conductor cross-section with up to 8.5 A per contact and the voltage rating with up
