4-008-40-0261 4008400261 Glue Pot Temperature Sensor for Homag Edgebander

A glue pot that sits a few degrees off ruins more edgebanding than a dull trimmer. The 4-008-40-0261 / 4008400261 temperature sensor is the replacement sensing part that reports pot temperature to the machine, so the melt stays at the viscosity your glue supplier specified. It is listed for the glue pot of Homag edgebanders, carries type designation R1QW-38/13L12, and ships by DHL, FedEx or UPS. Both part number formats name the same sensor. Price on request.

Three things ruin an edgebanding shift, and they trace back to one part. The glue pot drifts off its set point and nobody notices until the band lifts at the panel ends. The operator blames the glue, then the pressure roller, then the feed speed. When the fault lands on the sensor, the replacement quote takes weeks.

This is a replacement temperature sensor for the glue pot of a Homag edgebander, listed under part number 4-008-40-0261, also written 4008400261. Both formats name the same part, so a parts list, an invoice and a search box may each show a different one. The listing carries type designation R1QW-38/13L12.

The probe reads the melt temperature in the pot and passes it to the machine control, which then holds the glue at working viscosity instead of guessing from a timer. Precision is the whole job: a sensor reading high pulls the pot down, a sensor reading low lets the glue cook, and either way the first 20 metres of banding look fine before the ends fail.

The assembly is a metal-bodied probe with the lead and fitting needed to sit in the glue pot, following the original part rather than a bracket of our own. It ships as a woodworking machine spare, not a bench instrument. Single units go by DHL, FedEx or UPS; price is quoted per order.

Six facts decide whether this is the right order, and all six are on the listing:

• Direct replacement for part 4-008-40-0261 — matched by the number on the failed unit, not by a photograph.
• Two formats, one part — 4-008-40-0261 and 4008400261 resolve to this sensor; either can be quoted or searched.
• Type designation R1QW-38/13L12 — published with the part so a service manual can be cross-checked before ordering.
• Temperature sensing, not guessing — the probe reports melt temperature to the control loop, which acts on a real reading.
• High precision sensing — tight reading accuracy keeps the pot at the viscosity the glue maker specified, which is where adhesion is decided.
• Durable probe body — body and lead are built for a pot that runs hot through a full shift, so the part stays in service.
• Easy to use on a live machine — remove the failed probe, seat the new one in the same port, reconnect the lead: no drilling, no adapter plate.
• Edgebander spare, not a bench instrument — catalogued under edge banding machine spare parts, so lead and connector match the machine harness.
• One-stop sourcing — cups, pads, rollers, heating elements and sensors can share one shipment.

Maintenance teams choose between two bad options: wait on a dealer quote for a part that costs less than its freight, or keep running a pot that reads wrong and rework the banding. This sensor is the third option.

• Stop reworking banding at the sander. A correct reading holds the melt at working viscosity, so a peeling end is fixed at the glue pot instead of at the finishing line.
• Order by number, not by hope. Two accepted number formats plus the R1QW-38/13L12 marking mean the parts list already in your maintenance file is enough to place the order.
• Short downtime. Because fit copies the original probe, the swap fits inside one maintenance window instead of becoming a modification job with its own schedule.
• Fewer repeat failures. A probe built for continuous heat in a glue pot replaces a general-purpose sensor that fails early, so the replacement interval lengthens.
• Lower freight per part. Cups, pads, rollers, heating elements and sensors ship from one stock, so a single DHL, FedEx or UPS shipment carries a full maintenance kit.
• A quote without a negotiation. Send the part number and the quantity and you get a price for that quantity, not a catalogue round trip.
• A spares strategy, not a single part. One sensor on the shelf turns a drift fault into an hour of work, not a week on a dealer.

Yes, provided your parts list names this number for the glue pot sensor. The listing is written for the glue pot of Homag edgebanders and is ordered against the number on the failed unit, so compare that number before ordering rather than the shape of the probe.

Yes. The two strings are the same part number written with and without separators. The listing accepts either, so an invoice showing 4008400261 and a label showing 4-008-40-0261 describe one sensor.

Compare the pot temperature reading against the set point before you order anything. If the display holds set point while the glue behaves cold, or if it drifts in a way that repeats, the reading is the suspect; a heater that fails usually fails outright and the pot never reaches temperature.

No. Fit follows the original part, so the probe goes into the same port and the lead reconnects to the same harness point. No adapter plate, no new drilling, no change to the glue pot itself.

It is the type designation published with this sensor listing. Use it to cross-check the part against a service manual or an existing label before the order is placed.

By DHL, FedEx or UPS, whichever suits the destination. The quote you receive states the shipping method and the lead time for the quantity ordered, so confirm those two lines before paying.

Price is quoted per order rather than published, because quantity and freight change the total. Send the part number and the number of pieces you want and you get a price for exactly that.

Yes. Sensors, suction cups, chain pads, pressure rollers and heating elements are stocked together, so they can leave in one shipment and clear customs as a single consignment.
