SENSOR BALLON HL1027-1 J9810-00000-0A Toyota JAT-500 Air Jet Loom Weft Detection Part

Product Overview

Balloon sensor to original number J9810-00000-0A for the Toyota JAT-500 air jet loom. Item code HL1027-1.

The JAT-500 is still running in plenty of mills where the machine earns its keep on short runs and sample work, and the parts are getting harder to source than the looms deserve. This sensor is the balloon detection head for that model. When it weakens, the symptom is usually misread as a yarn problem: stops that cluster on fine counts, a balloon that looks normal but trips the feeler at high speed, sensors that work again after the yarn path is re-threaded, or a head that fails only when the package is nearly empty and the balloon shape changes.

Applications & Compatibility

Supplied to weaving mills maintaining Toyota JAT-500 machines, including mills keeping a small number of 500s alongside newer looms.

• Compatible with: Toyota JAT-500 air jet loom
• Original part number: J9810-00000-0A
• Our item code: HL1027-1
• Different model, different sensor: HL1028 uses J9810-00000-00 for JAT-600 / 610 / 710
• Related glass window: HL1030 (J9810-00020-00) for the 600 / 610 / 710 series

J9810-00000-0A and J9810-00000-00 differ by the trailing suffix, and the suffix is not cosmetic: they serve different machine generations. Order against the number printed on the old sensor. If the print is gone, send a photo of the connector side and the mounting face and we will confirm the match before dispatch.

Quality Standard

• Sensitivity matched to the original so the existing amplifier settings stay usable.
• Detection verified against a moving balloon sample, not only a static test.
• Housing sealed against the lint and size mist that collect around the yarn path.
• Connector and lead length matched to the JAT-500 harness for plug-in replacement.
• Mounting face machined flat so the head sits square and does not read the frame.
• Individual protective packing with the sensing face shielded.
• Warranty covers manufacturing defects (case-by-case evaluation). Impact damage and damage from incorrect wiring are excluded.

Frequently Asked Questions

Q1: Is this the same sensor as the JAT-600 / 610 / 710 version?
No. This is J9810-00000-0A for the JAT-500. The 600 / 610 / 710 machines use J9810-00000-00, listed as HL1028. Check the suffix on the old part.

Q2: The loom stops on fine yarn counts but runs clean on coarse. Could the sensor cause that?
It can. A weakening head loses margin when the balloon is small and fast. Confirm by checking whether the stops follow the yarn count and package fill level rather than a fixed position in the pick.

Q3: I can find JAT-500 parts nowhere. Do you hold stock?
We supply this sensor regularly. Stock is available in small quantities; tell us your requirement and we will confirm availability and lead time before you commit.

Q4: Does it need re-setting after fitting?
Sensitivity is matched to the original, so normally not. If the loom requires adjustment, follow the manual rather than widening the window, which hides a real fault.

Q5: What about the warranty?
Warranty is offered against manufacturing defects, evaluated case by case. Impact damage and damage from incorrect wiring are not covered.
