Microtest 8740K Cable Tester (1024-Point, 2-Wire)

The Microtest 8740K Cable Tester provides 1024-point connectivity and insulation testing for high-density cable assemblies and complex wire harnesses. With double the test point capacity of the 8761K, the 8740K addresses large harness assemblies found in automotive body wiring, industrial control panels, and telecom infrastructure where connector pin counts exceed 512 points. The 2-wire measurement method delivers fast continuity and resistance verification optimized for production throughput.

Multi-DUT Testing

Multi-DUT testing capability allows multiple smaller harnesses to be tested simultaneously in a single fixture, dramatically increasing throughput for high-volume production of repetitive harness assemblies. This feature is particularly valuable for automotive wiring loom manufacturers producing hundreds of identical sub-harnesses per shift, where testing individual harnesses one at a time creates a bottleneck.

Integrated Hipot and Production Features

Integrated hipot testing verifies insulation integrity without fixture changes, and 500 programmable test files with barcode-driven recipe selection support mixed-model production lines where different harness variants run on the same test station. The self-learn function creates test files automatically from a reference sample, reducing setup time for new product introductions. Pass/fail sorting with handler interface output enables integration with automated fixture systems for lights-out production testing.

Applications

The 8740K serves automotive body harness manufacturers, telecom infrastructure cable assemblers, industrial control panel wiring shops, and white goods appliance harness producers. The 1024-point capacity covers the largest harness assemblies in these industries without requiring expansion modules or fixture splitting.
