SSW675

(Two Element 双开关量 Speed Switch速度开关 Tachometer Output转速表输出 Overspeed to 10KHz 超速上至10kHZ)

SSW Series are respectively one, two, and three element electronic speed switches. They are powered by a DC battery supply and receive engine speed information from a magnetic speed sensor.

Both the SSW675 and SSW676 sense and signal a low speed setting (CRANK termination) and a high speed setting (OVERSPEED). The SSW676 has a third mid speed setting that can be used for several purposes such as parallel indication, underspeed, or general auxiliary contacts. The single element SSW674 has a wide range of adjustment and can be used for any one of these three functions.

    The Magnetic Speed Sensor detects when ring gear teeth, or other ferrous projections, pass the tip of the sensor.  Electrical impulses are produced by the sensor’s internal coil and sent to the speed control unit.  The signal from the magnetic speed sensor, teeth per second (Hz.), is directly proportional to engine speed.  Over 20 styles currently available through GAC (then link to Mag Speed Pick ups)
