1.25 mm HPI Wire-to-Board Connectors

TE Connectivity's 1.25mm High Performance Interconnects (HPI) Wire-to-Board Connectors are single-row and dual-row post headers available in various colors to allow users to color code the systems. These HPI connectors offer vertical and horizontal (right-angle) connector mounting for versatility, and the square-peg technology enables mating with multiple products. The 1.25mm small-factor locking connectors can be used where signal or low power needs to be routed through a device. The reduced size of the connectors allows greater flexibility, and the external locking feature ensures secure mating retention. This helps to improve system reliability by helping to prevent accidental unmating. These connectors are suitable for smart locks, small appliances, smart lighting, smart meters, vending machines, drones, data communications, washers/dryers, automotive, industrial, and LED lighting.
