Rugged, Spring-Loaded Wire Termination connectors

With the new Series 868 connectors, MILL-MAX offers extremely resilient spring and target connectors with solder connections. The cable terminations have solder cups for fixing wires and cables as well as flange insulators and mounting options.

868 Series connectors are available in 4mm pitch and 2-6 positions. The heavy-duty spring pins have 1.27 mm (0.050") diameter tappets, which have strong bending and bonding strength under shear forces. Each spring pin is designed for 9 amps at a temperature increase of 10°C and contact resistance less than 20 mΩ.

As a special distributor Heilind offers with the products of the series 868 robust connectors, which can be fastened safely to housings or printed circuit boards thanks to the mounting lugs, which are integrated into the insulators.
