Manual Wire Terminal Pull Force Tester with 500 N Dial Gauge WM-817

›

The WM-817 is a lever-operated bench tester that verifies crimped terminals by pulling them off the wire under a calibrated load. Capacity is 500 N with ±0.5% tolerance across a 50 mm stroke, read on an analog dial force gauge — a digital-display version is available on request. The wire clamps in a serrated vise, the terminal seats against the gauge side, and one smooth pull on the lever loads the joint until it holds or fails. At 10.6 kg and 45 × 26 × 16 cm, it sits right next to the crimping press.

Specifications

Key features

• Lever-driven sliding table applies a smooth, even pull, so the reading reflects the crimp itself rather than a jerked start
• Serrated vise jaws grip the wire without slipping — the joint, not the fixture, decides the result
• 500 N capacity at ±0.5% covers the pull-off classes of common automotive and appliance terminals in one bench unit
• At 10.6 kg it lives beside the crimping press, so first-off checks happen at the machine instead of a walk to the lab

What it processes

• First-off and hourly crimp pull checks beside terminal crimping presses
• Incoming QC on purchased cable assemblies, pigtails and jumper wires
• Connector pin, lug and splice retention spot checks on the production floor

Suited for: bench-side pull verification of crimped terminals, lugs, pins and splices up to 500 N — the fast, everyday check that keeps a crimping line honest between laboratory audits. Not suited for: joints specified above 500 N, or tests that must produce force-elongation curves at controlled speed — for those, pick the WM-812 dual-column tensile testing machine, the 5 kN servo machine with 0.05–500 mm/min speed control and PC-recorded curves.

Send a bag of your crimped samples and we pull them on camera with the dial in frame, so you see the readings live before you commit.
