DK series pressure switches are housed in pressure die cast aluminium powder coated enclosure (IP65) and are recommended for panel mounting or outdoor service. Stage differential can be set in these 2SPDT versions (DK series). Both microswitches are synchronised for operation such that the stage difference (or gap) can be adjusted from minimum 15 % of FSR to a maximum of 50% of FSR (on falling setpoints). The repeat accuracy is better than 2 % FSR. Two separate connectors to DIN 43650 are provided for electrical wiring for two independant circuits. Pressure port is 1⁄4 " BSPF standard.
