Shine Motor high and low pressure switches (SH-134a series) are specially designed for air conditioning systems. They integrate precise pressure sensors and reliable switch mechanisms to ensure the safe and efficient operation of refrigeration systems. This product is suitable for household, commercial, automotive air conditioners and refrigerators, etc. It is compatible with R134a refrigerant, supports 9mm/11mm external thread interfaces, double-pin connection, and single-pole single-throw structure (normally open/normally closed optional).
Core function: When the system pressure is lower than 0.2MPa (insufficient refrigerant) or higher than 3.14MPa (pipeline blockage), the power supply is automatically cut off to protect the compressor and pipeline from damage. It automatically resets after pressure is restored, with a sensitive response of less than 1 second. It adopts welded sealed stainless steel sensors and fully enclosed switches, with IP67 water and dust resistance, temperature resistance ranging from -40℃ to 125℃, and a service life of over 100,000 cycles.
