<Specifications>
Tempreture characteristics.
Terminals(cable is sold separately)
Cable Model No. RT-PAW-C1
Connector: SM06B-SRSS-TB (JST)
Housing connector: 06SR-3S (JST), Cable size AWG30
Contact pin SSH-003T-P0.2-H, Housing connector: SHR-06V-S-B(JST)
※Remarks
power supply is 3.3V. DO NOT USE 5V.
Quiescent current is 22mA at LED on.
LED1 and LED2 termnials are accepted by digital signal.
Photo1 and Photo2 terminals give voltage. You need no amplifier.
Operating principals
PAW sensor operated by light sensors as follows. Please use under appropriate pressure because it is broken precise equipment if you push strongly.
Virtual coordinate
PAW sensor can read virtual coordinate as following area. They can be read switching LED.
Flowchart
PAW sensor data reading flowchart and timing chart are as follows.
Calculation of difference
Each product has calibration values on the back.
Labels are serial number and calibraition value.
Please calculate correct value according to following equation.
⊿H = Cna(V-V0)2 + Cnb(V-V0)
⊿H: vertical difference
Cna:calbration valuea(n is ch1~ch4)
Cnb:calibration value (n is ch1~ch4)
V: detected Voltage (mV)
V0:voltage without any weight(mV)
Others
PAW sensor is light sensor. Therefore, it is weak for strong light from surface and back. Please make sure to focus on strong light to PAW sensor.
PAW sensor is consist of soft urethane and thin PCB. It will be broken if you put strong pressure. Please remark to use appropriate pressure.
Keep dry.
To avoid regradation, do not keep and use wet and high tempreture place.
Please keep away from fire and high tempreture.
Please put cable to connect in right position.
Do not pull urethane.
Calibration value is for normal shape. You can’t use calibration value if you customized.
Otherwize, not to use heavy pressure and so on.
