4008400057 Heating Sensor 0-250 GRAD PT100 7124 L 250 For Homag Machine

The 4008400057 Heating Sensor is a PT100 thermocouple for Homag machines, measuring 250 mm long and rated for 0 to 250 Celsius. It reads temperature at the glue point and feeds the signal back to the machine control. Confirm your machine uses Homag part number 4008400057 and that the 250 mm probe length matches the mounting depth before ordering. Customisation is supported.

When a Homag edgebander starts cycling heat on and off or throws a temperature fault, the first suspect is often the sensor at the glue pot. A failed or drifting probe makes the control compensate for a reading that no longer matches the glue temperature. Replacing the 4008400057 sensor restores the signal the control uses to hold the 0 to 250 Celsius range.

This is a PT100 platinum resistance thermocouple with a 250 mm probe length, identified by Homag number 4008400057. It fits Homag machines that call for that number. To confirm the fit, check the existing sensor's part number and probe length against 4008400057 and 250 mm, and verify the control's input is PT100.

Mounting follows the original sensor's location at the glue unit. The 250 mm length sets how far the probe reaches into the heated zone, so match it to the old part rather than forcing a different depth. A correct fit gives the control a stable resistance signal across 0 to 250 Celsius, which keeps glue temperature regulation consistent.

Customisation is supported, and the sensor is available with glue. For an enquiry, send the machine model, the existing Homag number 4008400057, the 250 mm length, and the required 0 to 250 Celsius range. State whether you need the glue variant and any customisation, and ask for packing details before ordering.

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

• Glue-line temperature sensing — The sensor is available with glue and mounts at the glue unit, giving the control a temperature signal from the point where adhesive is applied.
• Probe reach into heated zone — A 250 mm probe length sets how far the sensor reaches into the heated zone, so the reading reflects the temperature at the working depth.
• Platinum element for signal stability — The PT100 platinum resistance element changes resistance with temperature, giving the control a measurable signal across the 0 to 250 Celsius range.
• Range covers common glue settings — Rated from 0 to 250 Celsius, the sensor covers the glue pot and application temperatures used on Homag edgebanders within that range.
• Direct replacement for Homag number — Carrying Homag number 4008400057, the sensor is tailored specifically for Homag machines that call for that part number.
• Customisation for non-standard builds — Customisation is supported, so buyers with a non-standard mounting depth or connection requirement can request a modified sensor.
• Fit check by part number and length — Confirm the existing sensor shows 4008400057 and a 250 mm length before ordering, and check the control input is PT100.

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

• Restores a temperature signal the control can trust. A PT100 element rated 0 to 250 Celsius gives the machine control a resistance signal that tracks glue temperature, so heat cycling responds to the actual reading rather than a drifting probe.
• Takes the guesswork out of replacement. Matching Homag number 4008400057 and a 250 mm length against the old sensor confirms the fit before the order is placed, avoiding a return and a second shutdown.
• Matches the probe depth to the heated zone. The 250 mm length is the same dimension as the original part, so the probe reaches the working depth without adapters or a changed mounting position at the glue unit.
• Covers the full working temperature band. A 0 to 250 Celsius range spans the glue pot and application temperatures on Homag edgebanders within that band, so one sensor type covers the usual settings.
• Customisation keeps non-standard machines running. When a standard 250 mm probe will not fit a modified glue unit, customisation is supported, so the sensor can be built to the mounting depth the machine needs.

Check that your machine calls for Homag number 4008400057 and that the existing sensor is 250 mm long. Also confirm the control input is PT100; if all three match, the sensor is the correct replacement.

It covers 0 to 250 Celsius. That range takes in the glue pot and application temperatures used on Homag edgebanders within that band, so the control reads across the full working span.

Yes, the 250 mm length matches the original sensor dimension. Match it to the old part before ordering, because probe depth at the glue unit depends on that length.

Yes, customisation is supported. Tell the supplier what is different from the standard part, such as mounting depth or connection requirement, and they can quote a modified sensor.

The sensor is available with glue. State on your enquiry whether you need the glue variant, so the supplier quotes the version that suits the glue-point location.

Send the machine model, Homag number 4008400057, the 250 mm length, the 0 to 250 Celsius range, and whether you need the glue variant or customisation. Ask for packing details too.

PT100 means a platinum resistance element whose resistance changes with temperature. The control must accept a PT100 input for the 4008400057 sensor to give a usable temperature signal.

It mounts at the glue unit in the original sensor's position. Keep the 250 mm probe length matched to the old part so the probe reaches the same depth in the heated zone.
