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 leads are normally PVC; cables routed along the chassis or near the exhaust are quoted with XLPE insulation or a PUR jacket. 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?

Cables used under the chassis are supplied with sealed overmolded connectors and an AdBlue resistant jacket, so the connection survives wash-down and road spray. 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 lead is mapped to a specific engine or after-treatment connector, so pin count, keying and termination follow your sample or drawing. 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.

SCR Diagnostics Cable

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

Product Overview

This SCR diagnostics cable is a custom cable assembly that connects a diagnostic tool, test box or NOx sensor to the SCR (AdBlue) system connectors on heavy-duty trucks and off-highway engines.

The range covers 37, 35, 23, 20, 19, 18, 16, 14 and 12-pin diagnostic leads (SCR-EM-37P, SCR-KA-35, SCR-AB-23P, SCR-CU-20P-2P, SCR-SI-19P, SCR-CA-18P, SCR-TE-16P, SCR-TE-14P, SCR-CA-14P, SCR-BO-12P, SCR-SI-12P), NOx sensor cables (SCR-NOX, SCR-NOX-J), the sensor cable (SCR-SS), converter cable (SCR-CONVERT), 2-pin injector and extension cables and the 2.0 diagnostic lead (SCR-BO-2D).

Each lead is built to the engine or after-treatment connector on the drawing. Cactus Electronics has produced diagnostic cables since 2009, to IPC/WHMA-A-620, with 100 % electrical testing before shipment.
