Automatic pneumatic quick clamping
Connect conductors quickly and conveniently.
Simply insert the conductor into the pilot hole until it presses against the bottom of the hole.
This activates the clamping process to the terminal of the conductor.
At the end of the test, the clamps are all reopened together.

The so-called „pneumatic clamp“ is supplied with compressed air. Test objects are often only equipped with free lead ends without plug. The lead to be contacted is inserted approx. 1cm in the clamp´s borehole. At the borehole´s bottom there´s a flexible valve plate. As soon as it is pressed down by the lead, the integrated valve reacts and makes a clamping cylinder in the clamp push against it. By this the contacting is established.
A black push button is installed on the clamp to disconnect the contacting.
It is no problem to operate any number of clamps by means of the compressed air supply. In case the entire compressed air supply is interrupted, all clamps open at the same time. This is perfect, as it is possible to quickly open all contact points in parallel when a test is finished.
SCHLEICH delivers a wide range of proven pneumatic clamping devices.
The contacting is realized in 2-wire technology with the result, that ohmic resistances lower than 1-10 Ω may not be reliable measured due to the contact resistance in the clamp.
In case of these low resistances is is recommended to perform the test with 4-wire technology and Kelvin clamps.
