1. INTRODUCTION
This instruction sheet provides assembly and
disassembly procedures for Mini-Universal 
MATE-N-LOK 2 connectors used in free hanging or 
pc board applications.
Dimensions in this instruction sheet are in metric
units [with U.S. customary units in brackets].
Figures are not drawn to scale.
NOTE

Reasons for reissue of this instruction sheet are
provided in Section 6, REVISION SUMMARY.
2. DESCRIPTION (See Figure 1)
The pin header is available in vertical and right-angle
configurations. The plug housing and cap housing
accept the contacts listed in Figure 1. The housings
are polarized for proper alignment when mating. Keying
plugs are available to provide additional polarization
when mating the connectors. Positive locking features
prevent accidental disengagement of mated connectors.
3. ASSEMBLY PROCEDURE
3.1. Inserting Contacts
1. Select the appropriate pin and socket contacts
from Figure 1. Terminate the contacts according to
Application Specification 114-1111.
2. Rotate the wire end (back) of the housing 180
degrees along the pivot track until the first tooth of
each latching arm engages — the housing is in the
open position. See Figure 2.

3. From the wire end of the housing, align each
terminated pin or socket with the appropriate
contact cavity. Then grasp the wire directly behind
the contact insulation barrel and push the contact
with a twisting motion into the contact cavity until
the contact stops and the housing cone fingers
engage. See Figure 3, Detail A.
Terminated pin and socket contacts are
interchangeable between the housings. This or

4. After all required contacts and keying plugs have
been inserted into the housing, move the housing to
the close position. Grasp the wire end of the housing
and push it until the second tooth of each latching
arm engages as shown in Figure 3, Detail B.
3.2. Inserting Keying Plugs
1. Select an empty contact cavity of the housing to
be keyed. Ensure that the corresponding contact
cavity of the mating housing is empty. If it is not, the
keying plug will not engage.
2. With the housing in the open position (refer to
Figure 2), insert the keying plug into the wire end of
the housing. See Figure 4.
If removal of the keying plug is necessary, manually
or using pliers, grip the keying plug, and pull it from
the contact cavity using a twisting motion.

3. After all keying plugs have been inserted into the
housing, move the housing to the closed position.
Grasp the wire end of the housing and push it until
the second tooth of each latching arm engages
(refer to Figure 3).

3.3. Mating Connectors
1. Verify that the contact positions of the mating
connectors are identical.
2. Align and push the housing into the mating
connector until it bottoms and the locking latch
engages with the locking tab. See Figure 5.

CAUTION
4.2. Extracting Contacts
To prevent damage to the connector, the housing
must be in the open position before removing any
contacts.

!
CAUTION
1. Deflect the latching ears one at a time, then
lightly pull the wire end of the housing away from
the housing until the first tooth of the latching arms
engage. See Figure 7.
Take care not to over deflect the latching ears.
