Dual-row connectors

1 May 2013 Interconnection

Due to the small dimensions – the 50-pin male connectors show dimensions of only 24,2 x 4,7 mm with different heights – robustness was crucial during their development and, as a result, the male connectors are provided with reinforced side walls. Secure mating is ensured by coding and blind mate guide alignments, providing an increased locking range.

A unique feature for this miniaturised device size is the double-sided spring contact. The reliable, high-quality contacts are based on a proven and patented principle which ERNI has scaled down for smaller dimensions.

To support various PCB applications, parallel (mezzanine), orthogonal (90°) and coplanar configurations are available. With different heights for the male and female connectors, board-to-board distances from 5 mm to 20 mm can be realised for mezzanine applications.

Despite their miniaturisation, the new connectors offer a high mating tolerance with allowed misalignment tolerances of longitudinal and transverse axes of ±0,7 mm. The allowed angular inclination tolerance is specified within ±4°. The connectors are available in pin counts between 12 and 14. They are specified for more than 250 mating cycles and their tin-plated pins can carry up to 2,3 A per contact at 20°C.

The male connector is available with SMT termination. The robust plastic housing of the female connector withstands high temperature and is suitable for lead-free reflow soldering. Tape and reel packaging supports automatic assembly.
