Board level products for harsh environments


Proven, reliable and robust connectors


The 127 series is a medium-density range of multi-contact plug-in connectors for printed circuit boards. This range of 2.54[.100] staggered grid, low profile connectors meets the common harsh environmental requirements. A wide range of fittings and guides, as well as numerous contact terminations, provide more flexibility to PCB designers.

A well-proven technology

The 127 series uses a 2.54 mm [.100 in] staggered grid pitch with 2.54 mm [.100 in] between rows, available in 2 or 3 rows. The contact technology is based on the turning fork and blade concept. Using advanced copper alloys provides optimized electrical conductivity as well as long-term mechanical reliability.

A large choice of attachments on Printed Circuit Boards

Different styles, from 17 to 144 contacts with various terminations: straight, right angled 90°, crimp barrel, solder cup, SMT and wire-wrapping. Hybrid patterns, with a combination of 3 to 10 special cavities, permit the usage of coaxial, power contacts, as well as optical termini.

The 127 series connectors are available in 3 different versions: HE801/ HE804 / HE807
