Item Value Operating area (see note 1) 6.5 ±1 mm Sensitivity variation (see note 2) –1.4 mV/µm ±10% max. Resolution (see note 3) ±10 µm max. (Ta = 25°C) Linearity (see note 4) 2% F.S. (full scale) max. Note: 1. Distance from Mounting Reference Plane to Target. 2. The sensitivity is defined as slope of the line and it represents the variation in the output voltage per unit length between different products. 3. This is the value of the electrical noise width in the output signal converted to a distance under the following conditions. (1) A/D conversion time: 50 µs max. (2) Ripple noise in the power supply voltage (Vcc): 10 mVp-p max. (3) Low-pass filter time constant of the downstream signal processing circuit: 0.4 ms (4) Distance from mounting reference plane to target: 6.5 mm 4. This is the peak-to-peak value of the deviation of the signal output from a straight line. A linearity of 2% F.S. indicates the following value: (1) Distance full-scale converted value: 2 mm × 0.02 = 0.04 mm (40 µm) (2) Output voltage converted value: 1.4 mV/µm × 40 µm = 56 mV (for a sensor with a sensitivity of 1.4 mV/µm) ■ Engineering Data Sensitivity change ratio (%) 5 Output voltage (V) 4 3 2 1 5 100 4 80 3 60 2 1 0 −1 −2 −3 −5 5.5 6.0 6.5 7.0 7.5 8.0 Pulsed Forward Current Rated Curve (ms) Vcc=5V Distance: 6.5 mm Duty ratio (%)= 100 tFP T ×100 tFP 40 20 0 −20 −40 T 10 Recommended operating area 1 −60 −80 −4 0 5.0 Temperature Characteristics (Typical) Pulse width (tFP) Dependency of Object on Reflection Factor (Typical) Output change ratio (%) Operating Distance Characteristics (Typical) 0 Operating distance (mm) 20 40 60 80 100 −100 −40 −20 0 20 40 60 80 0.1 100 0 Ambient temperature (°C) Reflection factor of object (%) 20 40 60 80 Duty ratio (%) ■ Circuit Diagram PSD I/V Amplifier V1 V1+V2 OUT A/D port Output PLS (LED optical signal) 5 0 5V PLS LED D port Timer GND Object 5 Sensor output Microprocessor (Reference) ASIC 0 Output voltage corresponding to the distance Micro-displacement Sensor The sensor output is obtained by adding a pulse signal to the PLS terminal. An output cannot be obtained merely by adding a DC voltage to the PLS terminal. The output will be a pulse output synchronized with the PLS signal. The output must be held with a latching or sample-and-hold circuit in the microprocessor. ■ Typical Application Detecting Paper Thickness in Printers Detecting Two Sheets of Paper Detecting Sheet Thickness Micro-displacement Sensor Paper Micro-displacement Sensor Roller Shaft Roller Displacement Sensor Sheet Z4D-B01 Microphotonic Devices (Micro-displacement Sensor) 201
