Motor Terminal Plugs
Test plugs for contacting motor terminal boards
Every motor manufacturer is familiar with the issue of time-consuming contacting of the motor terminal board.
Motor test plugs enable fast contacting of 6-, 9- or 12-pole motor terminal boards in 2- or 4-wire technology.

Contacting precise and fast.
Every motor manufacturer knows the problem of time-consuming contacting of the motor terminal board. But the motor cannot be tested without appropriate contacting.
In order to save a lot of time, SCHLEICH produces different contacting methods for motor terminal boards.
Motor test plugs enable fast contacting of 6-, 9- or 12-pole motor terminal boards in two- or four-conductor technology. For motors with winding resistances lower than 10 Ω, four-wire technology offers the great advantage that the ohmic resistance measured values are not falsified by the contact transfer resistance between the test plug and the threaded bolts.
In order to make contacting the motor terminal board more user-friendly and time-saving, we have developed special motor test plugs that use collets to clamp and securely contact each threaded bolt of the motor terminal board individually. The collets are closed by means of clamping levers.
Since the motor test plug is often placed very hard on the terminal board bolts, the test plugs have an exchangeable wear plate on the mating side. The bolts are guided through conical funnel-shaped holes in the wear plate to the collets. This makes it much easier to attach the motor test plug.
The housing contact based on a spring-loaded contact pin is also integrated in the motor terminal board connectors as a single or double contact.
SCHLEICH offers a great variety of different motor terminal boards.
