PC/104 and PC/104 Plus Connectors
PC/104 and PC/104 Plus connectors are an industry-standard connector system used in PC/104 Embedded PC module stack applications. The PC/104 module stack is designed to use less space and at a lower cost than an equivalent backplane system, by utilising stackthrough connectors to interconnect PC boards within a stack. Standard height between module boards is 0.6 (15.24mm). PC/104 connectors are 2.54mm pitch, either 32+32 or 20+20 ways. PC/104 Plus connectors are 2.00mm pitch, 4 x 30 (120) ways. The sockets have a tuning-fork style of contact. Solder or press-fit tail options are available, as are accessories for the range.
