What is the operating temperature rating of this harness?

Standard PVC-insulated assemblies are rated to 80 °C; XLPE or TPE insulation raises the rating to 105 °C. Workshop cables are normally PVC; cables for machines working outdoors year-round are quoted with a PUR jacket that stays flexible in the cold. The exact operating range for a part number is stated on its drawing and confirmed in the sample test report.

Is this overmolded harness waterproof?

The connector is overmolded over the cable, so the plug withstands rain, mud and wash-down in the field, and sealed machine-side connectors are used where the drawing specifies them. The ingress protection level (typically IP67 for a mated pair) is specified on the drawing and verified during sample validation. Non-overmolded assemblies can be supplied with heat-shrink or grommet sealing instead.

Can I customize the pinout and connector type?

Yes. Pinout, connector series and gender, cable length, wire gauge, jacket colour and overmold shape are all customer-defined. Each cable is mapped to one machine brand and one service tool, so pinout and termination are defined by the pair you use. Send a drawing, a sample, or a pinout table and we return a 2D/3D drawing prepared to IPC/WHMA-A-620 for approval before tooling.

What is your MOQ for custom cable?

MOQ is confirmed per project and depends on harness complexity, connector cost and tooling. Prototype and pilot batches are accepted before mass production, so a new programme can start with sample quantities. Samples are produced in 3–7 working days and mass production runs 20–30 days after approval.

What testing standards do you apply for harness?

Production follows IPC/WHMA-A-620. Every assembly is 100 % electrically tested for continuity, insulation resistance and withstand voltage; the in-house lab adds temperature and humidity cycling, salt spray, connector insertion and withdrawal force, and cable bending tests. Inspection records are kept in the ERP system.

OHW Diagnostics Cable

Name: OHW Diagnostics Cable
Brand: Cactus Electronics
Availability: InStock

Product Overview

This OHW diagnostics cable is a custom cable assembly that connects a service tool to the diagnostic port of off-highway machines - excavators, loaders, tractors and trucks from Bobcat, Caterpillar, Hitachi, Komatsu, Volvo, Scania, Massey Ferguson and Carraro.

Existing builds include machine-specific cables for Bobcat (OHW-BOBC-C), Hitachi (OHW-HITA-C), Massey Ferguson (OHW-MASS-C1, OHW-MASS-C2), Scania CAN engine 4-pin (OHW-SCAN-C), Carraro (OHW-CARR-C), Caterpillar (OHW-CATE-C), Komatsu (OHW-KOMA-C), J1939 backbone (OHW-BACK-C) and Volvo Penta diesel 6-pin and 8-pin (OHW-VOLV-C2, OHW-VOLV-C6, OHW-VOLV-C8).

Each cable is built to the machine-side connector and the tool-side interface on the drawing. Cactus Electronics has produced diagnostic cables since 2009, to IPC/WHMA-A-620, with 100 % electrical testing before shipment.
