2-Head Conveyor Type Needle Detector HN-2870C-120/140/160/180, HN-2780G-100

Able to detect φ0.8mm ferrous steel ball at 120mm sensor height. Innovative sensor checking system by Auto PreChecker (optional) saves time.


  • Two-head sensors are set at different angles to minimize a detection difference made by direction of broken needles
  • Large sized LCD – Newly improved visibility and operation from previous models. Various settings such as sensitivity, language mode, etc. can show current machine condition on the display very well.
  • Newly developed sensor – Ability for detection of foreign object is upgraded by newly developed search coils and optimized magnet position.
  • Enlarged sensitivity equality
  • Needle position indication – Machine can detect location of the broken needles, makes searching for them easier.
  • 100-step sensitivity adjustment setting
  • Able to detect as small as φ0.8mm at detecting 100mm height
  • When needle detector detects a foreign object in a product, it rings an alarm and returns the product to the operator
  • Equipped with counter function
  • Foot switch and restart function (standard) – Restart function enables easy restarting of the conveyor belt without pushing the start button.
  • New convenient function for sensor test – For two head conveyor type needle detector, front sensor can be inactivated during rear sensor test.
  • Conveyor speed changing function – If machine detects sewing accessories, conveyor speed can be changed to 3 steps through the passage.


Optional device (please indicate in enquiry if you want any of these options)

  • Printer – prints inspection records and counter results
  • Product guider – optional equipment for HN-870C,2870C. This appears as standard equipment on HN-780G, 2780G.
  •  Auto PreChecker – makes sensor checking more accurate and quicker. By using PreCheck bar (Specialized test brock) & system, you do not need to check each coil one by one. The system checks sensor automatically. You can also keep the PreCheck results if you choose the optional printer.
