FEELER PRINT BOARD YHE-0171 J9201-10011-00 Toyota JAT-710 JAT-810 Loom Circuit Part

Product Overview

Feeler print board to original number J9201-10011-00 for Toyota JAT-710 and JAT-810 air jet looms. Item code YHE-0171.

This is the board that turns the feeler's optical signal into a decision the loom can act on. When it begins to fail, the feeler itself looks healthy — clean window, correct alignment — yet the stops keep coming, often with a pattern no mechanical adjustment explains: weft feeler errors that appear on random picks, a board that behaves differently after the cabinet has warmed up, a channel that stops responding only at high pick rates, or setting values that drift and will not hold after adjustment. Boards fail this way because a weakened input stage still works until the signal gets marginal.

Applications & Compatibility

Supplied to weaving mills and loom electrical teams servicing the weft feeler system.

• Compatible with: Toyota JAT-710 air jet loom
• Compatible with: Toyota JAT-810 air jet loom
• Original part number: J9201-10011-00
• Our item code: YHE-0171
• Related feeler parts: YHE-0149 / YHE-0150 feeler body and lens, YHE-0158 / YHE-0162 second feelers

Before fitting a new board, confirm the fault is on the board and not upstream: clean and re-seat the feeler connectors, check that the optical windows are clear, and verify the supply rails are stable. If the errors persist with known-good feelers fitted, the board is the remaining suspect. Match the original number J9201-10011-00 on the board edge; adjacent numbers in the J9201 series are not interchangeable.

Quality Standard

• Board layout and connector positions matched to J9201-10011-00 for drop-in replacement.
• Input stage tested with a simulated feeler signal, not only a power-on check.
• Settings verified to hold after adjustment, so the loom does not drift back into fault.
• Components rated for the warm, humid air of a weaving shed control cabinet.
• Conformal coating against fine lint and size mist.
• Anti-static bag with foam, packed so connectors cannot be stressed in transit.
• Warranty covers manufacturing defects (case-by-case evaluation). Damage from incorrect supply wiring or reversed connectors is excluded.

Frequently Asked Questions

Q1: How do I know the board is faulty and not the feeler?
Fit a known-good feeler first. If weft feeler stops continue with a clean window and correct alignment, the board is the remaining suspect.

Q2: The fault only appears when the cabinet is warm. Does that fit a board failure?
Yes. A marginal input stage often works when cold and fails as temperature rises. Note whether the stops follow warm-up; that points at the board rather than the optics.

Q3: Do I need to re-teach the settings after replacement?
The board is supplied to the original configuration. Where the loom requires setting entry, follow the manual, and confirm the values hold rather than drifting back within a shift.

Q4: Are other J9201 numbers interchangeable with this board?
No. Match J9201-10011-00 exactly; adjacent numbers in the series serve different circuits and functions.

Q5: What about the warranty?
Warranty is offered against manufacturing defects, evaluated case by case. Damage from incorrect supply wiring or reversed connectors is not covered.
