Cable pull- and tensile-test devices are used to precisely and repeatably measure the pull-off, tensile or holding force of cables, wires, crimped terminals, connectors or insulation components. They are essential tools in quality assurance, mechanical testing and material evaluation, and are widely used in production, cable assembly, automotive applications, electronics and laboratory environments.
Modern systems apply a defined pulling motion — constant or controlled — while simultaneously capturing force and displacement. Motorized units can measure forces ranging from a few newtons to several kilonewtons. With graphical representation of force-displacement or force-time curves, pull-off behaviour, break force, material strength and connection quality can be assessed accurately.
These devices are available in various configurations: compact benchtop models for series testing or crimp verification, motorized test stands for higher loads, handheld devices for simple tensile tests, or specialized systems for cable harness and connector inspections. Depending on the device, test parameters such as pull speed, test mode (tension, hold, break), measurement range or gripping fixtures can be adjusted to match the sample requirements.
Cable pull- and tensile-testers play a crucial role in ensuring the safety, durability and compliance of mechanical and electrical connections. They provide documented measurement results, statistical evaluations and reliable test protocols — indispensable for quality standards and certification processes.
