PullTester 25

Pull Testing Machine

Schleuniger’s PullTester 25 is a dual-range, motorized, bench-top unit designed to measure pull-test forces of crimp and ultrasonic weld connections on a wider range of wires than single-range pull test devices. Pull test values are critical parameters for quality control and assurance.

This versatile machine has two measuring ranges, which are individually calibrated enabling use of its 500 N (110 lbf.) scale for small wires, while easily switching to its 1,000 N (220 lbf.) scale for larger wires. This dual-range capability ensures the highest accuracy for the widest range of applications. Hand actuated or pneumatic pull test devices can give inconsistent data depending on the operator or pull rate. Some standards specify that a test device must pull with a consistent rate.

The Schleuniger PullTester 25 is equipped with a speed-controlled motor, ensuring consistent pull rates throughout the measuring range resulting in repeatable and accurate data. Pull forces can be measured in poundforce, Newtons or kiloponds. The standard 12-position terminal holder accommodates a wide variety of terminals to suit most applications. A variety of terminal holders, however, are available upon request.

The PullTester 25 is a dual-range, motorized benchtop device for measuring pull forces of crimp connections as well as ultrasonic metal welding connections on a broader range of wires than single-range pull test devices.
