and life span
There is no light emitting, light receiving elements, nor an electrolytic capacitor inside the sensor, which is breakable.
The life span of general light emitting and light receiving elements is forty thousand hours. Being exposed to hotter temperature accelerates deterioration process even further. Some PLGs are used an electrolytic capacitor.
Resistor NO Use Use
The adjusted value might fluctuate.
Light and rigid Glass Epoxy Substrate makes sensing part more resistant to vibration shock. The circuit is protected by moisture-proof coating resin.
There is a glass slit disk which is vulnerable to vibrations and shocks, and it leads to cracks easily.
Vibration resistance 200m/s2 100m/s2
Shock resistance 2000m/s2 1000m/s2
Protection rating IP66 IP55~66(Depends on types)
Pulse count selection YES
The output pulse number can be changed by internal switch.
The output pulse number depends on glass slit, and cannot be changed.

ezSCOPE is a sensor visualization tool. By connecting the two lines of the sensor output line to the ezSCOPE main unit, it is possible to capture the sensor internal data via the USB to the PC. The captured data can be displayed on the PC monitor in real time with numerical values and waveforms. It also has a data backup function. The wiring from the sensor to ezSCOPE can be extended. Since the sensor connection input part of ezSCOPE is insulated, it doesn't affect the sensor operation.

The infrared transmission module (option) can be used to transmit data to ezSCOPE main unit.
