product description

KDS710 series electronic pressure switch, built-in high-precision pressure sensor, adopts transistor output, NPN/PNP output is optional, output has the characteristics of no delay, no jitter, etc., and has a long service life.

KDS711 can preset an alarm value, which can be used as a single-point alarm switch, or it can preset the hysteresis to realize the control function.

The high voltage is closed and the low voltage is disconnected.

KDS712 can preset two pressure alarm values, which is suitable for the use of strong vibration and high-frequency actions such as on-board air compressors, trams, subways, etc., and also suitable for hydraulic machinery, automatic control equipment and other applications that require impact resistance and fast response. Scenes.

Applications:

◇ Vehicle air compressor

◇ High-speed train

◇ Hydraulic equipment

◇ Automatic control equipment

◇ Automated production line

◇ Other occasions instead of mechanical pressure switch

Technical characteristics

☆ 0~0.1...1.0...60MPa range optional
