The Wacker Neuson Snap Disc Sensor 200 F Auto is a genuine OEM component designed for the HI260 and HI1000 series indirect air heaters. As a direct-sourced Wacker Neuson part, the is manufactured to the exact specification required by these heaters, ensuring the thermal cutout function operates precisely as intended. Compatible across multiple HI1000 configurations — including diesel, gas, and DGM electric brake and surge brake variants — this sensor is the correct replacement for all listed HI260 and HI1000 machines.
Key Features
- OEM-Spec Thermal Calibration — Genuine Wacker Neuson manufacture ensures the 200°F snap-action threshold is exactly calibrated, so the sensor opens and closes at the correct temperature every time.
- Direct Drop-In Replacement — Engineered to match the original mounting footprint and electrical connection of the factory sensor, allowing straightforward installation with no adaptation.
- Broad HI-Series Compatibility — Confirmed fitment across HI260 and HI1000 series heaters, covering diesel, gas, and DGM configurations with both electric brake and surge brake setups.
- Protects Heater from Overtemperature Damage — A correctly functioning snap disc sensor automatically interrupts operation when the unit exceeds safe temperature limits, preventing heat exchanger damage and extended downtime.
- Critical Safety Component — As the primary automatic overheat cutout in an indirect-fired heater, this sensor plays a direct role in safe operation; using a verified OEM replacement maintains the integrity of that protection.
A snap disc sensor — sometimes called a thermal cutout or bimetal disc thermostat — is a temperature-activated switch that monitors heat levels inside the heater unit. When the temperature reaches the rated threshold (200°F in this case), the disc snaps to its opposite position and opens the electrical circuit, shutting the heater down before temperatures reach a damaging or unsafe level. Once the unit cools sufficiently, the disc snaps back and allows normal operation to resume. A worn or out-of-calibration snap disc sensor may fail to trip at the correct temperature, leaving the heater running beyond safe limits, or it may nuisance-trip at normal operating temperatures, causing the unit to shut down unexpectedly on the job.
