PullTester 27

Pull Testing Machine

Schleuniger’s PullTester 27 is a dual-range, motorized benchtop device designed to measure pull forces of wire crimp connections as well as ultrasonic metal welding connections on a wider range of wire than single-range pull test devices. The PullTester 27 is specially suited for quality assurance in a production environment.

  • Dual LCD displays for simple programming and operation
  • Speed-controlled motor for consistent pull rates
  • Simple LCD display for easy programming & read out
  • Repeatable & accurate data
  • Dual-range for improved accuracy over a wider range of wires
  • RS 232 interface for curve analysis & statistics with optional WinCrimp PC software
  • Two versions available
  • Two selectable pulling rates
  • Networking capabilities (optional)

Schleuniger’s PullTester 27 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 versions with two measuring ranges each, which are individually calibrated, enabling use for small or large cables.

  • PullTester 27 (standard): 2,000 / 5,000 N (440 / 1,100 lbf.)
  • PullTester 27-10 (special): 5,000 / 10,000 N (1,100 / 2,200 lbf.)

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 27 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 terminal holder can be designed and manufactured based on your application. In addition, a variety of terminal holders are available upon request.
