Extensions with metal holes This range of PTH extension boards is available in two combinations: standard and super. The standard 64 // 64 range is assembled with a DIN connector (front and back), and is supplied with ejector levers. The super version has a 96 // 96 connector and is supplied with all standard extension pieces plus gold-plated wrapping terminals, a connection pad and a DIN logic analyser reverse connector. Height can be extended in multiples of 3U, thanks to the addition of an intermediate plate. Compatible with systems 160 and 220 mm deep. Voltage and current can be measured by a complete super version assembly or by simple division of the tracks and fitting of pins to allow the addition of connecting jumper switches.
