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.

CAUTION

The wire end of the housing must be in the open

position before inserting the contacts.

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.
