The range of compact and reliable connectors from ERNI Electronics has expanded. The MaxiBridge (2.54mm pitch) and MiniBridge (1.27mm) series will shortly be joined by the MicroBridge series in a 1.27mm pitch. The MicroBridge product family has been designed specifically with the requirements of customers from 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 high 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 1.27mm pitch, the MicroBridge is extremely robust and withstands the vibrations in vehicles thanks to double-sided interlocking. The compact design is suited 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 two 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 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 8.5A per contact and the voltage rating with up to 70VAC/DC. The MicroBridge connectors are suitable for both manual and automatic assembly. ERNI Electronics is presenting initial prototypes of the family at electronica 2016 (Hall B2, Booth 518).
