Tier 1High-reliability line
Military-grade hermetic thermostats, engineered in the EU
Sealed thermal protection for defense and high-reliability electronics — Klixon-class performance without the export paperwork or the year-long queue. ITAR-free, factory-calibrated, and backed by verifiable certification and provenance documentation.
01Why us
The three axes the incumbents cannot defend
ITAR-free
EU-based supply chain — no US export-control friction on your bill of materials or your program schedule.
Weeks, not quarters
Realistic lead times against the 26–52 weeks typical of US-made hermetic parts, with qualification lots on request.
−55 °C … +150 °C
Hermetically sealed, glass-to-metal snap-action switching that survives vibration, altitude and condensation.
Documented
Test reports, certificate copies with verifiable numbers, and a MIL-PRF-24236-class parameter cross-reference.
02Where it fits
Built for programs, not appliances
UAV & loitering systems
Battery-pack and power-stage thermal cutoff that holds calibration under vibration and altitude cycling.
Military power supplies & converters
Sealed over-temperature protection for field converters, chargers and ground power units.
Avionics & ground support
High-reliability switching for radar, comms enclosures and avionics-adjacent industrial equipment.
Rail & aerospace-adjacent
Where a commercial open-frame disc is not qualifiable and a sealed, traceable device is mandatory.
03Versus the incumbents
Klixon-class performance, without the paperwork or the queue
Sensata/Klixon, Honeywell and Elmwood dominate the hermetic segment — trusted, but US-made, export-controlled, long-lead and indifferent to smaller regional programs.
| Axis | US incumbents | 8abc hermetic |
|---|---|---|
| Export control | ITAR / EAR-controlled (US origin) | ITAR-free, EU-based supply |
| Lead time | 26–52 weeks typical | Weeks; qualification lots on request |
| Minimum buys | High MOQ, rigid catalogue | Qualification lots, custom set points |
| Regional support | None for small EE/TR programs | Direct engineering, local languages |
| Documentation | Guarded, slow | Test data, certificates, provenance statement |
Comparison reflects typical segment conditions and varies by part number and program. Validate current incumbent lead times and export classification for your specific bill of materials.
04Provenance & qualification
The questions a reliability engineer asks first
Manufacture & origin
Devices are manufactured by Thermorex with EU-side inspection and lot acceptance. We provide a transparent provenance statement up front — no surprises in a supplier audit.
Qualification evidence
Test reports, certificate copies with verifiable numbers, and a MIL-PRF-24236-class parameter cross-reference. Independent verification of key parameters is available on request.
Export & compliance
Written export-control classification (EU dual-use screening) so every sale and claim stands on settled ground. We sign NDAs and support your qualification testing.
05Get the documentation
Request the qualification pack
Tell us your platform and set point. We send the datasheets, test reports, certificate references and the provenance statement — and follow up within 24 hours from an engineer, in your language. Qualification sample lots (5–20 pcs with lot acceptance data) are available on request.
