Product Description
PC/104 and PC/104 Plus connectors are an industry-standard connector system designed for PC/104 Embedded PC module stack applications. This system utilizes stackthrough connectors to interconnect PC boards within a stack, offering a space-saving and cost-effective alternative to traditional backplane systems. The standard height between module boards is 0.6 (15.24mm).
PC/104 connectors feature a 2.54mm pitch, available in 32+32 or 20+20 ways. PC/104 Plus connectors offer a 2.00mm pitch with 4 x 30 (120) ways. The sockets are equipped with a tuning-fork style of contact. Solder or press-fit tail options are available, along with associated accessories.
