McMURDO 200

High Density 2 mm Pitch Connectors

200 Series The Microconnector Series 200, two part printed circuit board connector system utilizes a 2mm (0.8in) pitch and has been specifically designed for use as a low voltage connector in high density packaging electronic equipment, particularly where military environmental classifications are to be met.

The product has a low profile of only 10mm nom. over the mated pair from p.c. to the terminations and provides a small footprint to increase packaging density. It is 180° polarized and at the same time fully shrouded to protect otherwise vulnerable micro-miniature contacts.

It is avialable as either a single row (Series 201) providing a 2 to 17 ways in 7 sizes or a two row (Series 202) providing 4 to 34 ways in 11 sizes.

Male connectors may have either straight or 90 ° p.c. terminations suitable for printed boards of 1.6mm nom. thickness. Connector retaining straps are fitted to provide adequate rigidity when mounted and mating latches are available as an option.

Female connectors may have either a straight p.c. termination for use with printed boards or printed wiring, or a choice of two sizes of crimp for use with discrete wires.

The socket contact is of precision two part construction having an outer shell fitted with an inner four-leaf contact with symmetrical short conatilever beams arranged in a radially opposing system.

Provision has been made for tooling for crimp contacts, to insert and withdraw the crimped contact from the moulding and de-latch and separated the mated connectors.
