TS Series Temperature Switch
The temperature switch is an advanced magnetic reed temperature switch designed for precise temperature monitoring and control in mechanical and electrical equipment, automobiles, marine vessels, and more. Ideal for providing reliable protection against overheating and overcooling conditions, it can be effectively installed in liquid, paste-like, fluid, and gaseous environments.
Operating on the principle of magnetic materials undergoing a phase transition near their Curie point (Tc), the switch precisely triggers a reed contact to open or close electrical circuits at predetermined temperature points. It offers exceptional reliability, stable performance, prolonged service life, vibration resistance, moisture protection, waterproofing, and explosion-proof characteristics, fully complying with EU RoHS standards.
- Exceptional thermal sensitivity with accuracy within ±1 ℃
- Minimal temperature drift during repeated switching operations
- Contacts securely sealed within a glass tube for enhanced explosion-proof safety
- Compact design enables easy integration into equipment
- Certified approvals including "CQC" and EX for assured quality
- Reliable self-holding stability at elevated temperatures
- Designed for continuous operation at temperatures up to 130℃
- Superior resistance to vibration and mechanical shock
- Simplifies logic cicuit by eliminating external holding relays or seal-in relays
- Effective thermal management in electric coolant fan systems, heating controls, anti-freezing measures, air conditioning units, and engine low-temperature warning devices.
- Ideal for reliable temperature regulation in refrigeration systems such as refrigerators, freezers, vending machines, and critical temperature alarm equipment.
- Thermal monitoring and overheating prevention in boilers, heating equipment, antifreeze heaters (e.g., air conditioners, freezer boxes), industrial machinery, and metal casing applications.
- Widely applicable to any industrial or commercial equipment requiring enhanced safety, reliability, and functional performance through precise temperature control.
