We supply the WM-835 digital crimp height micrometer for first-piece approval, applicator setup and routine terminal inspection. Its 0–20 mm measuring range, 0.001 mm display resolution and ±0.003 mm specified accuracy support dimensional checks against your terminal drawing. A pointed spindle and blade anvil reach the crimp measurement location, while a ratchet stop helps operators apply consistent measuring force.

Specifications

Key features

• Check the first crimp after a terminal, wire or applicator change against the required height before releasing the batch; the measuring contacts are shaped for crimp-height access.
• Read dimensions directly in 0.001 mm increments on the LCD, reducing the need to interpret a mechanical scale during repeated checks.
• Use the ratchet stop and one agreed positioning method to reduce differences caused by operators tightening the spindle by feel.
• Start with manual inspection records, then add the appropriate SPC connection when your customer or quality plan requires electronic capture. We quote the connection and collection equipment separately.
• IP65 protection supports use around workshop dust and splashes. Keep the contacts clean and dry for measurement, and verify the instrument within your calibration programme.

What it processes

• First-piece dimensional inspection of compatible crimped terminals
• Crimp-height checks after applicator adjustment or changeover
• Routine sampling at manual, semi-automatic and automatic crimping stations
• Inspection records for terminal and wire combinations with a specified crimp-height tolerance

Confirm the setup before the batch grows

A new terminal or wire combination needs its own accepted crimp setting. Matching the wire size on a machine label does not establish the correct crimp height. Use the terminal application drawing to define the measurement location and tolerance, then check the first pieces before continuing production.

We review your drawing and sample crimps to check whether the measuring contacts can reach that location. The gallery shows the hand-held instrument, a terminal measurement example, the contact geometry and the dimensional drawing. The displayed reading in the example is not a recommended target for your terminal.

Make repeated checks comparable

Clean the measuring contacts, verify the reference and position each sample consistently. Approach with the ratchet stop rather than applying extra pressure through the thimble. Follow the terminal drawing for the measurement location and keep the sample steady while reading the display.

Record the terminal and wire combination alongside the result. Where your control plan requires electronic capture, we match the SPC connection to the intended collection system. This lets you buy the recording equipment your process needs without assuming that every inspection station needs the same setup.

Complete the crimp quality check

Crimp height checks the formed dimension. Our WM-834 crimp force monitor watches the press waveform during production, while terminal pull testers check retention and the WM-813 cross-section system examines the formed joint internally. Choose the combination required by your terminal specification and customer acceptance plan.

WM-835 is our catalogue reference for this supplied inspection instrument. We identify the exact instrument and agreed documentation on the quote. Send your terminal drawing and samples with your inquiry so we can confirm the measuring arrangement and quote the required accessories.
