Screw-Clamp Switches for Extreme Conditions
When wire-lead or solder-lug connections fail under sustained vibration, thermal cycling, or radiation exposure — screw-clamp terminals provide a mechanically secure, maintainable alternative. Postek KWQM5-2-28 Series.
⚛️ Energy Facilities
- Hot cell manipulator limits
- Reactor auxiliary systems
- Waste handling interlocks
Screw-clamp terminal survives radiation where solder degrades. Hermetic seal prevents contamination.
🧪 Chemical Processing
- Corrosive atmosphere valve sensing
- Reactor vessel interlocks
- Pipeline pig detection
All-welded metal shell resists chemical attack. Screw terminals enable field replacement without soldering.
❄️ Cryogenic Storage
- LNG/LHe tank level sensing
- Cryo-pump status monitoring
- Cold box door interlocks
Rated for cryogenic operation. Screw-clamp maintains connection integrity through thermal cycling.
