Model WT3-201

Wire Crimp Pull Tester

The WT3-201 wire crimp pull tester is designed to measure the pull-off force of crimped wire and tube terminations. An ergonomic lever allows for easy application of up to 200 lbF (1,000 N) of crimp pull force. Adjustable wire terminal grip contains multiple slots for wire diameters up to AWG 3 (0.25 in [6.3 mm]). The tester accommodates most insulation types. Samples can be sent to Mark-10 for evaluation prior to purchase.

A large, backlit graphic LCD displays easy-to-read values, including real-time force, peak force, programmable pass/fail limits, units of measurement, and more. Data can be transferred to a PC or other data collector via USB, RS-232, Mitutoyo (Digimatic), or analog outputs. An analog load bar is shown on the display for graphical representation of applied force.

On-board data storage for up to 1,000 readings is included, as are statistical calculations and output to a PC. Unique automatic output / data storage / zeroing upon sample break helps automate testing processes.

An optional ring terminal fixture may be used to secure ring terminations, and an optional carrying case makes transportation simple and safe.
