Automatic Wire Crimp Pull Tester with Touch Screen, 500 N WM-820

Name: Automatic Wire Crimp Pull Tester with Touch Screen, 500 N WM-820
Brand: Wiromac
SKU: WM-820

HS Code 9031.80 500 N max (1,000 N optional)

The WM-820 is a motor-driven bench tester that pulls crimped terminals off the wire at a programmed constant speed and captures the peak force on a color touch screen. It tests up to 500 N (0–50 kg) at ±0.04 N accuracy with pull speeds from 10 to 800 mm/min — a 1,000 N version is available on request. Besides destructive peak-force pulls it runs non-destructive hold tests against a set load limit, stores 16 test programs, and connects to a PC and printer for peak graphs and real-time printout. At 10 kg and 430 × 180 × 210 mm it sits on the bench beside the crimping press.

Key features

Motor-driven pull at a set speed (10–800 mm/min), so every sample sees the same loading rate — readings compare sample to sample and shift to shift
Non-destructive mode holds a programmed load for a set time and releases, verifying the joint without scrapping it
Slotted terminal disc chuck and serrated wire vise seat common terminal and wire sizes without changing tooling; special wire specifications can be fixtured on request
16 stored programs recall load limit, hold time and speed per wire type — operators pick a recipe instead of re-keying settings
Test software plots the peak-force graph on a connected PC and prints results in real time for inspection records

What it processes

First-off and periodic crimp pull-off checks beside terminal crimping presses
Non-destructive lot verification of crimped leads that must ship after the test
Incoming QC on purchased cable assemblies, pigtails and jumper wires against UL pull-out values

Suited for: motorized, repeatable pull-off verification of crimped terminals, lugs and splices up to 500 N — destructive peak tests and non-destructive hold tests, with stored programs and printed records for lines that audit their crimp quality. Not suited for: joints specified far above 500 N or full material characterization with force-elongation curves — for high forces, pick the WM-811 terminal tensile testing machine (10–10,000 N, automatic clamping, tension curve and report printing); for standardized curve-recording tests on materials and assemblies, the WM-812 dual-column tensile testing machine runs to 5 kN with 0.05–500 mm/min servo speed control.

Send a bag of your crimped samples with your target pull-out values — we program the test, run your samples on camera with the screen in frame, and send you the readings before you commit to the order.

WM-820 — common questions

How is the WM-820 different from a hand-lever pull tester?

A hand lever loads the joint at whatever rate the operator pulls, so readings scatter. The WM-820 pulls with a motor at a programmed constant speed and records the peak automatically, which is what pull-out specifications assume. If a simple lever check is all your line needs, the WM-817 manual pull force tester covers the same 500 N range at a lower cost.

Can it test terminals without destroying them?

Yes. Set an upper force limit and a hold time, and the machine loads the joint to that limit, holds, and releases. A joint that survives passes and ships; only failed joints are lost. Destructive peak-force testing to full pull-off is available in the same program list.

What if my specification calls for more than 500 N?

A 1,000 N build of the WM-820 is available on request — tell us your target values when you inquire. For heavy lugs and specifications well beyond that, the WM-811 terminal tensile testing machine tests from 10 to 10,000 N with automatic clamping and report printing.
