Product Introduction – FUJI AA18D06 H04 / H04S Working Head Reference Point

Part Number: AA18D06

Product Name: Reference Point

Category: Alignment / Positioning Component

Used In: FUJI NXT H04 and H04S Working Heads

Product Overview

The FUJI AA18D06 Reference Point is a precision mechanical part designed to serve as the origin or "home" position marker for the H04 and H04S working heads in Fuji NXT series surface mount machines. It is essential for accurate head initialization, calibration, and repeatable positioning of the head during pick-and-place operations.

Key Features

High Precision Positioning
Enables the working head to reset or reference its position to ensure accurate component placement.

Mechanical Alignment Target
Works in conjunction with head sensors to define a fixed reference point in the X/Y/Z axis.

Stable and Durable
Constructed from high-strength materials to resist wear from repeated contact or sensor detection.

Designed for H04 & H04S Heads
Custom-fit for the Fuji NXT H04 and H04S models—ensuring compatibility and reliable function.

Applications

Used during machine power-on homing and routine head recalibration.
Serves as a mechanical landmark for the head to align internal encoders or movement counters.
Ensures consistent, precise component placement on PCBs by defining the head’s starting point.

Notes:

These components work together to enable precise head positioning during initialization or recalibration.
The reference point (AA18D06) must be mechanically aligned with the reference sensor (AA0WZ00) for accurate function.
Regular maintenance is recommended to ensure proper detection and avoid pick-and-place errors.

Part numbers may vary slightly based on head version or generation.
When replacing AA18D06, it’s best practice to inspect the sensor and wiring harness as well.

FAQ Guide – FUJI AA18D06 H04 / H04S Working Head Reference Point

1. What is the AA18D06 reference point used for?

Answer:
The FUJI AA18D06 reference point is a precision mechanical marker used in H04 and H04S working heads of Fuji NXT machines. It defines the zero/origin position of the head during machine startup, calibration, and motion resetting.

2. Which models is this part compatible with?

Answer:

Specifically designed for FUJI NXT H04 and H04S working heads.
Not compatible with other head types (e.g., H12, H08, H24) unless otherwise specified.

3. How does the reference point work?

Answer:

The reference point is a fixed mechanical structure mounted on the head.
It is detected by a reference sensor (such as AA0WZ00) during homing or recalibration.
This enables the machine to precisely align internal positioning systems with physical hardware.

4. What are common symptoms of a damaged or misaligned reference point?

Answer:

Inconsistent head homing behavior.
Placement offset or misalignment during operation.
"Reference not found" errors during machine initialization.
Sensor misread or inconsistent feedback during calibration.

5. What components work with the AA18D06?

6. Is the reference point a wear part? How often should it be replaced?

Answer:

The AA18D06 is a non-moving mechanical component, so it rarely wears out.
However, it may become misaligned, scratched, or damaged by impact or long-term use.
Check alignment during major head maintenance or if positioning errors occur.

7. How is the AA18D06 installed or replaced?

Answer:

Mounted using a bracket (AA18D10) on the head frame.
Should be aligned precisely to match the sensor detection range.
Recalibration of the head may be required after replacement.

8. Is this part sold individually or in a kit?

Answer:

Typically sold individually.
Some vendors may offer it bundled with the sensor and bracket as a reference point kit.

9. Can non-OEM reference points be used?

Answer:

Technically possible, but not recommended.
OEM AA18D06 parts are precision-made to match Fuji’s head alignment tolerances.
Using non-original parts may lead to offset errors or sensor misreading.

10. Where can I purchase the AA18D06 and related parts?

Answer:

From official Fuji distributors, SMT parts suppliers (e.g., SMTBOX, EAH Industrial), or Fuji’s service partners.
Ensure compatibility by verifying the part number and head model (H04 or H04S).
