PRINT BOARD FEELER J9201-10001-00 Toyota JAT-710 JAT-810 Loom Spare Part HL1021 Feeler Control Board

Product Overview

This is the feeler print board for Toyota JAT-710 and JAT-810 air jet looms. Original part number J9201-10001-00, our item code HL1021. It is the board that sits between the weft feeler head and the loom controller: it conditions the head signal, carries the detection level adjustment, and decides what the controller is told about the pick.

In a mill, this board is usually the last part to be suspected and the first to be blamed after the head has been changed with no result. Boards fail in a way that looks like a head problem, because the symptom is the same: weft stops on picks that were woven properly, then weft stops that no sensitivity setting will clear. The difference is that a board fault does not respond to cleaning or to a new head.

Before ordering, two checks are worth doing. First, look at the connector side of the old board for dulled or cracked solder and for heat marking around the regulator. Second, tap the control box lightly while the loom is running: if the weft signal drops out, the fault is on the board or its connector, not in the head.

The board is built to OEM-equivalent layout, so it mounts on the same points and plugs onto the same harness as the original. No rewiring, no modification of the control box, and no change to the loom program.

Quality Standard

• OEM-equivalent layout, mounting points and connector positions for direct replacement, no rewiring required.
• Every board powered and signal-tested on a bench before packing, not only visually inspected.
• Detection level swept across its full adjustment range, so the setting can be brought into the working window after fitting.
• Solder joints at the connector pins and the heavier components inspected under magnification for cracks and cold joints.
• Connector retention checked, since a loose plug on this board reads exactly like a failing head.
• Board cleaning and coating checked for residue that could bridge or corrode in a humid weaving shed.

Frequently Asked Questions

Q1: Will this board fit my JAT-710 or JAT-810?
It is listed for JAT-710 and JAT-810, original part number J9201-10001-00. Please confirm your model and send a photo of the old board before ordering.

Q2: How is this different from other feeler boards in your range?
Each board is tied to its own original part number and loom generation. Send a photo of the old board, connector side up, and we will confirm which one matches your machine.

Q3: How can I tell the board from the feeler head?
Fit a known-good head. If the weft stops continue and the detection level cannot be brought into range, the board is the likely cause. Tapping the control box during running is a quick confirmation: a signal that drops out points to the board or its connector.

Q4: Do I need to re-adjust anything after fitting?
Yes. Set the detection level after installation, confirm it holds across the adjustment range, then run the loom and check for false weft stops.

Q5: Can I order samples first?
Yes, sample orders are supported for quality checking before bulk purchase.

Q6: What about the warranty?
Warranty is offered against manufacturing defects, evaluated case by case. Damage from wrong supply voltage or improper installation is not covered.
