MILL-MAX Omniball spring-loaded contact product line with solder tail and solder-cup versions, provides options for different termination requirements including spring-loaded contact (patent pending). Device features a rolling ball interface, enabling mating components to engage in lateral, rotational and angular alignments while providing optimal electrical, mechanical, and structural reliability. Available in different tail lengths, devices are suitable for use on pcbs of various thickness. P/N: 7945-1-15-20-09-14-11-0 has a tail length of .079” (2 mm) while 7945-2-15-20-09-14-11-0 has a .118” (3 mm) long tail. The solder-cup version, P/N: 7949-0-15-20-09-14-11-0, is designed to accept wire sizes up to 20 AWG. It has two press-fit features, a barb, and a knurl, allowing the pin to be pressed in from either direction. The knurl, an anti-rotation press-fit feature, is preferred when maintaining solder-cup alignment is critical.
