A stabilized DC power supply with both positive and negative outputs, a ripple voltage of 3 mVp-p or less, and a current capacity of 100 mA or more is recommended. These photosensor amplifiers will not operate from a single output power supply. If using a switching power supply or DC-DC converter, then take measures to reduce ripple and noise effects on the measurements.
Make the following connections. Incorrect connections may cause malfunction.
|Red||Positive output terminal|
|Blue||Negative output terminal|
If operating from a battery, then check the battery's power. If the problem is not solved even after replacing the battery or switching to an external power supply, the main unit may be at fault, so consult our sales office.
The C6386-01 datasheet shows the photosensitivity measured using an LED light source at λp = 830 nm. To change the photosensitivity to "mV/lx" units, convert it to the case where a standard tungsten lamp at a color temperature of 2856 K is used. The values after conversion are shown below.
|H range||30 mV/μW||→||1.57 mV/lx|
|M range||3 mV/μW||→||0.157 mV/lx|
|L range||0.3 mV/μW||→||0.0157 mV/lx|
Low-noise coaxial cables are recommended to ensure the shielding effect. Commercially available BNC cables with a cable characteristic impedance of 50 or 75 ohms can also be used.
A cable length within 3 meters is recommended. Using a longer cable will cause noise. If a cable longer than 3 meters is required, consult our sales office for advice.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
