Product Introduction – FUJI AA79S11 H12HSQ Working Head Reference
Point
Part Number: AA79S11
Name: Reference Point (for H12HSQ Working Head)
Category: Positioning / Calibration Component
Used in: FUJI NXT H12HSQ Working Head
Product Overview
The FUJI AA79S11 Reference Point is a precision alignment component
used in the H12HSQ working head of the FUJI NXT SMT series. It
serves as a mechanical reference or origin marker to assist with
the accurate positioning, calibration, or homing of the head unit
during high-speed mounting operations.
Key Features
Calibration Accuracy
Enables the H12HSQ working head to recognize its exact position
relative to the X/Y/Z axes, ensuring micron-level precision in part
placement.
Mechanical Origin Function
Acts as a mechanical “home” or zero-reference point for alignment
sensors or encoders in the working head assembly.
Wear-Resistant Construction
Made from hardened metal (e.g., tool steel or treated stainless
steel) to withstand repeated contact and mechanical movements.
OEM-Compatible Design
Manufactured to FUJI original specifications to ensure seamless
integration with the H12HSQ head and its control firmware.
Applications
FUJI NXT H12HSQ Working Head
Head position initialization at machine startup
Routine head calibration during maintenance cycles
Serves as a location reference for pickup nozzle or component
alignment

| Accessory Name | Part Number | Description |
| H12HSQ Working Head | — | The main working head unit where AA79S11 is installed; responsible
for component pickup and placement. |
| Reference Point Sensor / Detector | AA0WZ00 | Optical or magnetic sensor that detects the reference point to
establish the home/origin position of the head. |
| Reference Point Bracket / Mount | AA79B00 (example) | Mechanical bracket or fixture used to securely install the AA79S11
on the head frame. |
| Head Positioning Pin | AA9FR00 | Used in conjunction with the reference point for accurate
mechanical alignment. |
| Calibration Jig / Block | AA81A00 (example) | Tool used during calibration to ensure the reference point aligns
correctly with machine coordinates. |
| Z-Axis Stopper / Hard Stop | Varies by head model | Works together with the reference point to define mechanical travel
limits. |
| Nozzle Holder Base | AA89F00 | The nozzle base may align based on the reference point during
initial head setup. |
| Head Encoder Assembly | — | Internal encoder system that uses the reference point for resetting
position counters. |
| Working Head Main Cable | AA91A00 | Electrical harness that may carry signals from the reference point
sensor to the control board. |
Notes:
AA79S11 is a mechanical or sensor target, not an electronic sensor
itself.
The reference point sensor (AA0WZ00) is essential for
detection—ensure both parts are properly aligned.
Always check for head model compatibility—AA79S11 is specific to
H12HSQ, not interchangeable with other head types like H08M or H24.

FAQ Guide – FUJI AA79S11 H12HSQ Working Head Reference Point
1. What is the FUJI AA79S11 reference point used for?
Answer:
The AA79S11 is a mechanical reference marker used by the H12HSQ
working head in FUJI NXT machines. It serves as a home or
zero-point reference for the head’s positioning system, allowing
precise alignment and calibration of the working head during
startup, movement, and part placement.
2. Which machine and head is this part used on?
Answer:
Machine Series: FUJI NXT I / II / III
Working Head: Specifically designed for the H12HSQ head
It is mounted on the head frame and works with position detection
sensors to establish the head's exact starting point.
3. How does it function in the machine?
Answer:
When the machine powers on or recalibrates, the head moves to a
predefined position. The AA79S11 reference point is detected by a
sensor (e.g., AA0WZ00) to define a known origin or "zero" for the
head, allowing accurate and repeatable motion throughout the SMT
process.
4. Is the AA79S11 an electronic or mechanical part?
Answer:
It is a mechanical part—typically a precisely machined metal or
hardened surface—used as a target for a nearby sensor to detect
physical contact or proximity. It does not have electrical
components.
5. When should it be inspected or replaced?
Answer:
During regular head maintenance or calibration routines
If there are symptoms such as:
Head homing failure
Positioning errors
Sensor detection failure
It may need replacement if worn, bent, or misaligned
6. What are the related components?
Answer:
| Part Number | Description |
| AA0WZ00 | Reference point sensor (detects AA79S11) |
| AA79B00 | Bracket for mounting AA79S11 |
| AA91A00 | Main head wiring harness (connects sensors) |
| AA9FR00 | Alignment/locating pin |
| AA81A00 | Calibration jig for head position adjustment |
| H12HSQ | The working head unit where AA79S11 is installed |
7. Is the AA79S11 sold individually?
Answer:
Yes, it is typically sold as a single unit. In some cases, it may
be included in a head alignment kit or factory calibration toolset
depending on the service level package.
8. What are the key specifications?
Answer:
Type: Mechanical reference target
Material: Hardened steel or treated aluminum
Positioning Tolerance: Within ±0.01 mm (head calibration grade)
Mounting: Fixed via bracket or directly to the head frame
9. Where can I purchase it?
Answer:
FUJI authorized distributors
SMT aftermarket suppliers (e.g., SMTBOX, EAH Industrial)
Ensure you request AA79S11 for H12HSQ, as other heads use different
reference points
10. Can it be reused or cleaned?
Answer:
Yes—if not damaged, it can be reused after cleaning.
However, if the surface is scratched, bent, or worn, it should be
replaced to maintain high-precision head calibration.
