In addition, they feature low insertion and extraction forces that are a catalyst for easy mating relative to their contact size. The LSH Series delivers customers a contact life that can be maintained for up to 100,000 mating cycles and at an extremely low cost of ownership.

Weidmuller’s Omnimate 4.0 line of SNAP IN connectors include the MPS/MHS 6 PCB connector family that features a 6.35 pitch—the most compact solution to achieve an IEC 1000V, UL 600V rating, allowing space savings of up to 15% on the printed circuit board. The MPS 6 plugs are UL rated for 20 to 10 AWG and 30A. The MPS/MHS 6 joins Weidmuller’s existing Omnimate 4.0 line to bring the largest and broadest portfolio of products with a SNAP IN connection to market. With its unique spring-clamp design, SNAP IN connection technology simplifies system installation and boosts speed, reliability, and safety.

Versatys miniature power connectors from Axon Cable achieve the same performance as power D-Sub connectors while saving space and weight.
