PullTester 20

Pull Testing Machine

Schleuniger’s PullTester 20 is a motorized, benchtop unit designed to measure pull-test forces for a variety of applications. The most common applications are wire crimp and ultrasonic metal welding connections, but the design makes it possible to create custom fixtures for many other applications. Standards, such as IEC and SAE, specify that the device pulls at a consistent rate.

The Schleuniger PullTester 20 is equipped with a speed-controlled motor, ensuring consistent pull rates throughout the measuring range, which means repeatable and accurate data. Pull-to-break (destructive) tests can be measured in poundforce, Newtons or kiloponds.

The PullTester 20 is an economical motorized benchtop device for measuring pull forces of crimp connections as well as ultrasonic metal welding connections.
