Description
These legacy “Modular” edge card connectors are cut to the number of required contacts from an 85 way moulding and so have a continuous daughter board card slot. To prevent the daughter card moving axially out of the card slot the connectors can be mounted to the motherboard using metal or plastic end feet. When using plastic fittings a pair of cavities must be left empty at opposing ends of the body for them to clip into. The connector body is a green thermoplastic material, rated UL94 V-0 flammability. The McMurdo contacts can be fixed or replaceable, cantilever or bifurcated types designed for low insertion force and even pad pressure. Available from 5 to 85 way single or 10 to 170 way double sided the contact options include dip solder, solder eyelet and wire wrap; all in acid gold plated copper alloy. Polarising/location keys are available and can be purchased loose or factory fitted in specified positions.
These connectors prove reliable replacements in fit, form and function to the sadly lamented Thermodata Components ‘Modulo’ and Viking Connectors UK ‘VMA Series’ of 2.54mm pitch Modular connectors and are intermateable with other similar pitch connectors and circuit boards..
