PS3W1S Alco Spain Sales

The Alco PS3-W1S is a low-pressure switch featuring automatic reset functionality and fixed switch-point settings. It offers a pressure range from 0.3 to 1.8 bar, with a maximum allowable pressure of 27 bar and a factory test pressure of 30 bar. The switch includes a 7/16"-20 UNF female pressure connection with a Schrader opener. It is designed with a maximum allowable pressure up to 45 bar and a test pressure up to 50 bar. The switch is available in high and low-pressure versions, with a high-temperature variant featuring a snubber for direct compressor mounting (Range 6). Direct mounting reduces the number of joints, avoiding potential leakage. The device provides precise setting and repeatability and achieves IP65 protection with the appropriate cable and plug.
