Fuji S65846 – NXT Working Head Suction Nozzle Detection Sensor

Overview

The Fuji S65846 is a precision detection sensor used in the working head of Fuji NXT series placement machines. Its primary function is to detect the presence and status of the suction nozzle during component pick-and-place operations, ensuring accuracy and preventing placement errors due to missing or misaligned nozzles.

Key Features

Real-time nozzle presence detection to verify nozzle installation before operation
Compact and integrated design for seamless fit inside the working head
Fast response to enable high-speed machine cycles without delay
Supports both installation verification and error detection (e.g., nozzle drop, misalignment)
Helps prevent placement defects and head damage by identifying nozzle anomalies early

Application

Used in Fuji NXT I, II, III, and IV series machines
Installed directly on the working head (e.g., H01, H04, H12, H24, V12)
Monitors the suction nozzle holder to ensure the correct nozzle is installed and functioning properly
Assists with nozzle change detection and safety interlock systems

Typical Specifications

Benefits

Reduces placement failures by preventing missing-nozzle operation
Enhances machine reliability and uptime

FAQ Guide – Fuji S65846 NXT Suction Nozzle Detection Sensor

General Information
Q1: What is the Fuji S65846 sensor used for?

A: The S65846 is a nozzle presence detection sensor mounted inside the working head of Fuji NXT machines. It verifies whether a suction nozzle is correctly installed before or during operation, helping prevent pick-and-place errors caused by missing or misaligned nozzles.

Q2: Which Fuji machines use the S65846 sensor?

A: It is used in Fuji NXT I, II, III, and IV series machines, especially in heads like:

V12, H01, H08, H12, H24
These heads require precise detection to support high-speed, automatic nozzle changing and safe placement.

Functionality and Compatibility
Q3: What does the S65846 detect specifically?

A:

Detects whether a nozzle is mounted
Confirms correct engagement with the nozzle holder
Supports automatic nozzle changer (ANC) systems to prevent misplacement during nozzle swaps

Q4: Is it the same as a vacuum sensor?

A: No. The S65846 detects nozzle presence, while sensors like XS00920 measure vacuum pressure to confirm suction when picking up components. Both may be used together.

Q5: How is it connected to the system?

A:
The S65846 sensor connects to the head control board (e.g., 2AGKHA000402 or 2AGKHB008800) via a sensor signal cable such as XH01320 or XH01400. The signal is interpreted in real time by the placement machine’s controller.

Maintenance & Troubleshooting
Q6: What routine maintenance is recommended?

Clean the sensor lens/face to remove dust or flux residue
Inspect sensor mounting bracket and cable connections
Perform calibration if nozzle detection is inconsistent
Use Fuji’s diagnostic tools to verify sensor I/O signals

Q7: Common problems and solutions

Best Practices

Always perform sensor verification after head or nozzle replacement
Use only compatible Fuji nozzles to ensure proper detection
Clean sensor and surrounding parts regularly to avoid misreading
Keep spare sensors and cables on hand for quick replacement
Document nozzle detection errors to monitor wear trends
