COMPONENT SPECIFICATION C00531 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, cable to board and cable to cable. The range covers 2 to 96 ways, in various application methods. Female connectors are available for crimp, vertical through-board and surface mount termination. Male connectors are available for crimp, vertical or horizontal (90°) through- board and vertical surface-mount termination. Pre-Crimped wires and cable assemblies are also available in various options. The connectors are provided with a range of contact terminations (as shown in Appendix 1) that are gold or gold/tin plated. The contact zone of a gold plated contact is hard acid gold of 98% purity. The connector is intended for use as a low voltage connector in high packing density electronic equipment. The connector is polarised to prevent mis-matching and can be produced with a latching feature (L-Tek) or in a jackscrew (J-Tek) format, with or without board mounting. L-Tek and J-Tek connectors are available with low-frequency (LF) contacts, while Mixed Technology (Mix-Tek) connectors are also available with jackscrews, with a choice of power or coax contacts. NOTE: Some connector styles are available manufactured and tested to BS9525 F0033. All other connectors in the range are designed to the same specification. For cable assembly specifications see Component Specification C049XX (where XX is latest issue). 2.

COMPONENT SPECIFICATION C00531 APPENDIX 5 – 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 boardmount jackscrews should be fixed to the mounting board with fixings and 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, 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. NB: Care to be taken when aligning male and female threads to avoid cross-threading and possible failure of parts. 3. On disengaging the two halves of the connector turn each of the floating jackscrews anti- clockwise. Again ensure even loading by turning each screw in sequence for a maximum of one turn until the jackscrew disengage. The connector can then be easily pulled apart. 4. Board mounting fixings must be fitted before Wave soldering. 5. Board mounting fixings can be fitted before or after reflow soldering, as preferred by customer. If fitted before soldering, check that the fixings remain tight after soldering. - 14 -

COMPONENT SPECIFICATION C00531 APPENDIX 6 – INSTRUCTIONS FOR THE USE OF JACKSCREWS 1. Before engaging, the slot on the jackscrew should be at right angles to the length of the connector. 2. Push the connectors together. Once the connectors are mated, use a screwdriver to push down onto each 101Lok Jackscrew until the spring is compressed. Turn the Jackscrew 101 degreess, and release. The Jackscrew should remain partially compressed. 3. To disengage, use a screwdriver to push down on each 101Lok Jackscrew until the spring is compressed. Turn the Jackscrew anti-clockwise 101 degrees, and release. The Jackscrew will spring back to its uncompressed position. - 15 -
