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°) throughboard 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).

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 anticlockwise. 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
APPENDIX 6 – INSTRUCTIONS FOR THE USE OF
C00531
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.
