Description：
Tetra-lateral position sensing detector PSD400-LC is Manufactured with one single resistive layer for both one And two dimensional measurements. It feature a Common cathode and four anodes for this two dimensional Position sensing.
It offers high response uniformity, low dark current, and Good position linearity over 80% of the sensing area.
Features：
* High responsibility for IR laser.
* High speed response
* Low dark current
* High dynamic range
* Operating temperature is from -40 to +100℃
* Storage temperature is from -40 to +100℃
* soldering temperature is 260℃ @Max.5 seconds at the
Applications：
* Tool alignment and control * Leve*** measurements
* Angular measurements * Displancement and vibration monitors
*Automatic range finder systems *3 Dimensional vision
