What is a Construction Attachment Wire Harness and how does it work?

A Construction Attachment Wire Harness is a sacrificial continuous-resistance coaxial cable that is inserted along the length of an explosive charge. As the detonation front travels through the cable, it progressively short-circuits the conductors. A VOD recorder measures the resistance collapse over time and converts it into a velocity-of-detonation profile across the charge.

Which probe cable variant should I order?

Standard Green class covers most commercial blasting and quarry rounds. Blue (LR) is for deep-hole production blasts and long charge columns. HT is for hot-hole and sensitized emulsion environments. Kevlar-reinforced (K) is for abrasive borehole conditions and rough handling. SmartCable precision is for laboratory and explosives R&D programs.

What resistance per meter do you support?

Per-meter resistance is set per program. We commonly support values in the 10 Ohm/m range used by industry-standard VOD recorders, but we will match your recorder calibration and hold the lot resistance inside a tight tolerance window (typically ±2%) confirmed by lot-level measurement.

How long can a single Construction Attachment Wire Harness be?

Standard probe cables run from 1 m to roughly 30 m. Long-range LR variants extend that practical limit through reduced parasitic capacitance. For very long deep-hole programs, contact engineering with the column length, recorder model, and acceptable signal decay so we can confirm the right cable construction.

Are these probe cables single-use or reusable?

Construction Attachment Wire Harnesss are sacrificial. They are consumed in the blast. The product is engineered to survive transport, hole loading, stemming, and pre-detonation handling — and to present a clean baseline resistance to the recorder until the detonation front arrives.

What recorder-side terminations do you offer?

BNC, banana plug, screw-lug, and custom recorder-specific terminations are all supported. Tell us the VOD recorder model used in the field and we will match the launch geometry so probe cables drop into the existing fixture without on-site adaptation.

What documentation comes with each shipment?

Every shipment includes a lot-level certificate documenting the measured per-meter resistance, manufacturing date, and lot identifier. R&D and academic customers can request unit-level serialization for fully traceable cable-to-trace correlation.

What is your minimum order quantity?

We support prototype lots for initial recorder calibration and process qualification, scaling up to recurring multi-PO production volumes (hundreds of kilometers per year). Contact engineering with your forecast and program cadence for a phased proposal.

Sample-Iteration to Production Discipline

Multi-revision sample iteration through 6-12 months of OEM testing is normal for construction-attachment programs. We track each EC-series drawing through revision history, lock fixtures to revision-level, and ship 200-unit production batches once the drawing is signed off.

Why Construction-Attachment OEMs Choose Us

Attachment harnesses live in the harshest environment of any construction-equipment harness — and they have to be replaceable years later

EC-Series Drawing Discipline

We track each EC-series drawing through revision history, lock fixtures to revision-level, and re-ship the same drawing 2-3 years later without losing the geometry, the connector list, or the workmanship target.

Calibrated Deutsch HDT-48-00 In-House

Construction-attachment harnesses are mostly Deutsch DT / DTM / DTP / DTHD. We run calibrated HDT-48-00 tooling annually qualified to ISO 17025 — no generic ratchet crimper improvisation.

200-Unit Batch Cadence

The typical construction-attachment OEM batch is 100-300 units. We plan capacity, raw cable stock, and Deutsch terminal buffer for that profile so a 200-unit recurring run doesn't break the rhythm of the next-customer's pilot work.

Multi-Revision Sample Iteration

Attachment OEMs typically run 6-12 months of sample iteration before signing off the production drawing. We support that iteration cadence with sub-batch sample lots and ECN tracking through every revision.

Sales-Continuity Through Buyer Turnover

Attachment-OEM procurement teams have turnover. When the original buyer leaves, we maintain program continuity through formal hand-off — drawing status, fixture status, ECN history — so the new buyer doesn't restart the program from scratch.

Aftermarket Replacement Geometry Match

For service and aftermarket programs, we match the connector tail-to-cable OD geometry of the legacy harness so the replacement assembly drops into the field-machine without rework.

Australia (machinery OEM)

Year

2023-2026

Scenario: An Australian construction-machinery OEM building hydraulic attachments — earth augers, planetary drives, and adjacent attachment families — needed a wire harness supplier capable of multi-revision sample iteration over 18-24 months before signing off the production drawing, then steady 200-unit batch volumes after sign-off.

Challenge: Six different EC-series drawings (EC-100316, EC-100089, EC-100169, EC-001324, EC-001325, EC-001341) ran in parallel iteration; mid-program the primary buyer left the OEM, with a new buyer taking over and actively testing the latest sample lot.

What we did: Locked each EC-series drawing to its own fixture and revision history, supported the multi-revision sample iteration with sub-batch quantities, and bridged the buyer transition with a formal hand-off of drawing status, fixture status, and ECN history. New buyer received next sample lot ready for field test.

Result: Multi-revision sample iteration converged across 6 drawings, with the new buyer actively requesting additional new-product RFQs — relationship-health 4/5 across the buyer transition, program continuing into recurring 200-unit production cadence.

Program & Recorder Review

We review the VOD recorder family, probe length range, target resistance per meter, and field conditions before recommending the right variant family.

Variant Specification Lock

For each application — standard, long-range, high-temperature, Kevlar-reinforced, or lab precision — we confirm conductor stack, dielectric, and reinforcement before sample release.

Sample Build & Characterization

Initial sample lots are produced, measured for per-meter resistance, and compared to your recorder calibration. Adjustments locked into the production process window.

100% Continuity + Resistance Verification

Every probe cable is end-to-end continuity tested and resistance-checked before lot release. Sample-level per-meter resistance characterization on each production lot.

Documentation & Serialization

Lot certificate of compliance documents measured resistance values, manufacturing date, and lot ID. Serialization available for R&D and academic programs.

Logistics & Repeat Production

Reels labelled, packaged for transport, and shipped on mining-season schedules. Recurring POs supported with split air + sea logistics where seasonal demand requires.
