1. Interface definition
Identify both mating interfaces, approved component references, keying, orientation, and cable-exit direction. Use the connector selection requirements page to organize this information.

CUSTOM SIGNAL CONNECTIONS
Custom Sensor Cable Assemblies for OEM Equipment
Build the cable assembly around the sensor interface, equipment connection, routing path, environmental requirements, and customer-approved drawing.
Cablum manufactures customer-specific cable assemblies and can review drawings, specifications, component requirements, and project-defined inspection needs before quotation.
Quick answer
A sensor cable assembly should define the complete connection, not only the sensor name. Give the supplier:
- sensor-side and equipment-side interfaces;
- pin assignment and circuit function;
- length, routing, branch, and exit direction;
- protection and identification requirements;
- inspection and acceptance requirements.
PRODUCT ROLE
Connect the sensing point to the control system
A custom sensor cable assembly provides the defined electrical and mechanical connection between a sensing device and the equipment that receives its signal. The assembly may be point-to-point or part of a larger harness, depending on the customer drawing.
Its page role is narrower than a general data and signal cable assembly: it focuses on the information needed to quote and manufacture a sensor connection without assuming a protocol, connector brand, wire construction, or performance value.
Connector and material choices remain customer- and project-specific. Cablum can review customer-specified requirements but does not assume availability or approve substitutions without confirmation.
RFQ INPUTS
Define these six items before supplier review
The required detail depends on the sensor, equipment interface, installation, and customer acceptance criteria.
2. Pin assignment
Provide the customer-approved connection table, circuit names, polarity where applicable, and any unused or reserved positions. Mark open decisions instead of leaving them as supplier assumptions.
3. Cable path
Define overall length, measurement references, routing constraints, bend or movement considerations, and required connector orientation at installation.
4. Environment
State the customer-approved electrical, mechanical, temperature, exposure, and installation requirements. Do not rely on a general description such as “industrial” to define performance.
5. Protection and ID
Specify required sleeving, heat-shrink, restraint, labels, or other protection on the drawing. Exact materials and locations should be controlled by project documents.
6. Inspection scope
Define the applicable visual, electrical, dimensional, documentation, and acceptance requirements. Inspection is performed according to customer specifications and project requirements.
DRAWING CONTROL
Keep every interface decision in one controlled definition
A sensor description may identify what is measured, but it does not necessarily define the cable assembly. The drawing and BOM should align the interface, pin assignment, cable construction, length, protection, labels, and revision status.
Reference the approved BOM
List customer-approved component information and separate approved items from proposed alternatives.
Control length and orientation
Name measurement endpoints and show the connector view used to define orientation.
Record open requirements
Flag unresolved environmental, testing, or material decisions so the quotation does not silently convert them into assumptions.
For a broader document review, use the Wire Harness Drawing Checklist and BOM Requirements.
DECISION TABLE
Turn broad requests into quote-ready inputs
The supplier needs controlled project information rather than a generic sensor or cable label.
| Broad request | Question to resolve | Useful RFQ input |
|---|---|---|
| “Sensor cable” | Which two interfaces are connected? | Interface references, mating details, and orientation |
| “Shielded” | What project requirement does shielding address? | Customer-defined construction, termination, and grounding requirements |
| “Standard length” | Where does the measurement begin and end? | Length, reference points, route, and tolerance |
| “Test before shipment” | Which characteristic and acceptance basis apply? | Project-defined method, scope, limits, sampling, and records |

BUYER QUESTIONS
Sensor cable assembly FAQ
Provide the drawing or connection definition, approved component references, pin assignment, length and routing, environmental requirements, protection and labeling needs, quantity context, and project-defined inspection requirements.
Cablum can review customer-specified connectors and component requirements during project review. Selection, availability, approved alternatives, and compatibility must be confirmed for the specific project.
No universal construction should be assumed. Shielding and its termination should be defined from the customer’s electrical, environmental, and interface requirements for the application.
Inspection can be performed according to customer specifications and project requirements. The drawing or quality plan should define the applicable scope, method, limits, sampling, and record needs.
Cablum provides prototype support based on project requirements. Component availability, quantity, tooling, validation, and schedule are reviewed for the specific project.
