# Automotive Radar & Sensor Brackets

> A vehicle sensor bracket is an alignment part, not just a mount. Quote-critical features are the body datum, sensor clocking, mounting-hole position, interface flatness and any post-finish dimensions. CNC machining is appropriate for development parts and stiff production brackets where bent sheet cannot hold the required angular relationship.

## Components and applications

- Radar and lidar mounts
- Camera calibration brackets
- Wheel-speed and position-sensor mounts
- ADAS validation fixtures

## Recommended manufacturing route

1. Machine the vehicle-side datum first.
2. Finish sensor faces and locating holes in a common setup.
3. Apply finish with masked or compensated interfaces.
4. CMM-check position and angle to the datum reference frame.

## Drawing and RFQ controls

| Control | Guidance |
|---|---|
| Sensor clocking | Use profile or angular controls tied to the vehicle datum reference frame. |
| Fastener access | Confirm tool clearance and assembly direction around the installed sensor. |
| Post-finish size | Mark locating bores or faces that apply after anodizing or coating. |

## Inspection to define before production

- CMM position and profile report to vehicle datums
- Thread and locating-feature gauges
- Finish and masking verification on assembly interfaces

## Standards and documentation scope

- **PPAP / FAI**: Documentation level is defined by the customer at RFQ.
- **ASME Y14.5 / ISO GPS**: Position and profile should reference functional assembly datums.

## Buyer questions, answered

### Should a radar bracket use plus/minus dimensions or GD&T?

Use position, profile and angular controls tied to functional datums for the alignment features. Plus/minus dimensions alone can allow an assembly that passes inspection but points the sensor incorrectly.

### Can coating change sensor alignment?

Yes on locating faces and close-fit holes. State which dimensions apply after finish and where masking or machining allowance is required.
