Step 2: Push straight down gently and apply pressure to release
locking finger. This motion will release the locking finger, “picking”
is not required. Cavity plugs are removed in the same manner.
Do not apply any lateral force, this may damage the

Fixtures used for continuity testing must meet the row and pitch
dimensions as identified in Section 6.
Fixtures outside these requirements could result in damage to the
connector and/or terminal.
1. When testing the connector for continuity it is imperative that you do not damage
the terminals!
2. Pogo pins should be checked for damage or sticking several times a shift. This
should assure containment if an issue is found.
3. First a visual inspection of all the pins for damage should be performed.
4. Next a testing block should be used to depress all the pogo pins up into the
barrel. If there is a bent or sticking pin, it should remain stuck in the barrel of the
pogo pin. A damaged or stuck pin should be replaced before any additional testing
is performed.
Probing damage can occur:
1. If a sharp ended probe is inserted into the contact of the terminal it may damage
the plating and increase contact resistance
2. If an oversized diameter probe is inserted into the terminal, this will overstress
the beam in the terminal. This will create an environment for intermittent
connections, and increased contact resistance.
3. If a probe is inserted into the connector on an angle or off center it may damage
the terminal, and or the connector.

Section 6: Electrical Continuity Checking
•Preferred method of probing
Fixtures used for continuity testing must meet the row and pitch dimensions as
identified in Section 6. Fixtures outside these requirements could result in
damage to the connector and/or terminal.
Check electrical continuity on the terminal by inserting probe pin between
terminal access hole and terminal opening with a 0.50 mm probe.
Shown below are pictures of MX150 Sealed connector. Unsealed connectors
must be probed at the same location (between access hole and terminal
opening)

Handling in Plant:
Harness build board/fixture: Molex recommends moving the cell pack box or box to the line,
this will insure against damage. Parts should remain in Molex cell pack until assembled placed
