1. DESCRIPTION OF CONNECTOR AND INTENDED APPLICATION.
A range of 2mm pitch male and female rectangular, fully shrouded unsealed connectors with replaceable
contacts for interconnecting board to board and board to wire. The range covers female connectors suitable
for crimp or through board termination and male connectors available for straight or 90° through-board
termination. The connectors are provided with a range of contact terminations (as shown in Appendix 1)
which are gold or gold/tin plated. The contact zone of gold plated contacts is hard acid gold of 98% purity.
The connector is intended for use as a connector in high packing density electronic equipment. Low and
high frequency contacts can be supplied. The connector is polarised to prevent mis-matching and can be
produced with a jackscrew feature as required.

APPENDIX 3 - INSTRUCTIONS FOR THE USE OF CONNECTORS FITTED WITH JACKSCREWS.
Connectors are fitted with jackscrews where it is considered necessary to provide mechanical assistance in
ensuring a satisfactory engagement and separation of the connector. This may apply in cases where
engagement and separation forces are so high as to prevent satisfactory hand engagement, or where
access to connector is restricted. Jackscrews also provide a locking feature, preventing the connector from
disengaging under adverse conditions.
In order to obtain maximum effectiveness from the jackscrew system, the following rules for their use
should be observed.
1. The connector with the fixed jackscrew should be fixed to the mounting board by means of the male
thread on the jackscrew, and an M2.5 nut. The nut should be tightened to a torque of 21±2cmN.
2. On engaging the two halves of the connector after ensuring correct polarity, lightly push home the
floating half until the jackscrews touch. Then, maintaining the pressure, turn one of the floating
jackscrews clockwise, by means of a 2mm A/F hexagon key, until it engages with the fixed screw.
Repeat with the other screw.
Then screw in each jackscrew, ensuring even loading by applying a maximum of one turn to each
screw in sequence until the connector is bottomed. This will be evident by a sudden increase in the
torque required on the screw. This torque should not exceed 23cmN.
3. On disengaging the two halves of the connector turn each of the floating jackscrews anti-clockwise by
means of the 2mm A/F hexagon key. Again ensure even loading by turning each screw in sequence
for a maximum of one turn until the jackscrew disengages. The connector can then be easily pulled
apart.
