4-022-03-0257 Digital Position Indicator Counter For Homag 4022030257

This is a Homag digital position indicator counter, part 4-022-03-0257, also written 4022030257. It is type 0914 2.0I with a 2.0 spindle pitch and clockwise calculation direction, and it can replace type 0904 S-2. The indicator mounts directly to a rotating shaft and shows the position as a digital readout. To confirm the fit, check the part number on the head or the machine documents against 4-022-03-0257 or 4022030257, and check that the pitch you are replacing is the 2.0 pitch.

When an axis comes back to a setting and the readout no longer matches the cut, the operator stops trusting the number and starts measuring by hand. A worn or failed indicator on a Homag machine does exactly that: the adjustment drifts and every setup takes longer. Replacing the indicator restores a number the operator can set to.

The 4-022-03-0257, or 4022030257, is a digital position indicator of type 0914 2.0I. It carries a 2.0 spindle pitch and a clockwise calculation direction. It mounts on Homag machinery and can replace type 0904 S-2. To confirm the fit, read the number off the existing indicator and match it to 4-022-03-0257 or 4022030257, then check the pitch.

The unit mounts directly to a rotating shaft, so the shaft drives the indicator and the display follows the shaft turn. Pitch and calculation direction decide what that turn reads as, so the replacement must carry the same 2.0 pitch and clockwise direction as the unit it replaces.

Buyers order by part number, so send 4-022-03-0257 or 4022030257 with your enquiry, along with the type 0914 2.0I marking from the old unit and a photo of the shaft it sits on. That lets the counter be checked against the machine before it ships. Packing and customisation are not fixed here, so state what you need when you ask.

What the specification fixes, and what it leaves to the machine:

• Shaft mounting — Mounts directly to a rotating shaft, so the display follows the shaft turn without a separate linkage or belt between them.
• Pitch match — The 2.0 spindle pitch sets how far the shaft turns per displayed unit, so the readout matches the machine handwheel.
• Direction match — Clockwise calculation direction means the display counts the same way as the shaft it replaces, so the operator turns the way they always have.
• Old-type replacement — It can replace type 0904 S-2, which covers machines still running the older indicator when that unit fails.
• Type marking — Type 0914 2.0I is marked on the unit, giving the buyer a second check against the old part beyond the number alone.
• Number check — Part number 4-022-03-0257 or 4022030257 is the primary fitment check, read off the old indicator before ordering.
• Machine fit — Built for Homag machinery, so the mounting and shaft connection match the machine rather than needing an adapter.
• Setup time — A working readout lets the operator set the axis to a number instead of measuring the cut, which shortens each changeover.

What changes on the shop floor when the right part goes back in:

• Operators stop measuring by hand. Once the display tracks the shaft again, the operator sets the axis to a number instead of checking the cut with a rule, which takes the guesswork out of each setup.
• Fewer scrapped setup parts. A readout that matches the machine lets the first part of a run come out at the intended setting, so trial cuts and the scrap that comes with them drop.
• Old 0904 S-2 machines stay in service. Units running type 0904 S-2 can take this indicator as a replacement, so an older machine does not sit idle waiting for a part that is no longer fitted.
• One number to order against. The part number 4-022-03-0257 or 4022030257 is read straight off the old unit, so the buyer orders against the number on the machine rather than a description.
• Pitch and direction settle the fit. With a 2.0 spindle pitch and clockwise calculation direction stated, the buyer can compare both against the old unit before ordering and avoid a unit that reads wrong.
• Direct shaft mount, less to refit. The indicator mounts directly to the rotating shaft, so replacement work is confined to the shaft connection instead of a linkage that also has to come apart.

Check the number on the old indicator against 4-022-03-0257 or 4022030257. If it matches, and the old unit is type 0914 2.0I or type 0904 S-2, this indicator is the replacement.

It means the indicator is built for a 2.0 spindle pitch, so the display counts one unit per 2.0 of shaft travel. The unit it replaces must carry the same 2.0 pitch.

Yes. It can replace type 0904 S-2, so machines still running that older indicator can take this unit when the old one fails.

Clockwise. The calculation direction is clockwise, so the display counts in the same direction as a clockwise-turning shaft.

It mounts directly to a rotating shaft. The shaft turns the indicator and the display follows, so there is no separate linkage to line up.

Send the part number 4-022-03-0257 or 4022030257, the type marking from the old unit, and a photo of the shaft it mounts on, so the unit can be checked against your machine.

Packing and customisation are not fixed for this part. State what you need in the enquiry and it can be discussed against your order.

Do not order this one. Send the number and type marking from your old indicator with a photo of the mounting, and it can be checked against what you have.
