S8543 is a one-dimensional PSD with a long, narrow active area sealed in a surface mountable chip carrier package. The active area of
0.7 × 24 mm delivers excellent position detection characteristics.
Hamamatsu also provides L5586 infrared LED compatible with S8543.

*1: Within ±75 % from center to end of active area
*2: This is the minimum detectable light spot displacement. The detection limit is indicated by the distance on the photosensitive
surface. The numerical value of the resolution of a position sensor using a PSD is proportional to both the length of the PSD
and the noise of the measuring system (resolution deteriorates) and inversely proportional to the photocurrent (incident
energy) of the PSD (resolution improves). The resolution value listed in this data sheet was calculated under the following
conditions.
Frequency bandwidth: 1 kHz
Photocurrent: 1 μA
Equivalent input noise voltage of circuit: 1 μV (1 kHz)
Interelectrode resistance: Typical value (refer to the specification table)
*3: This is the upper limit of photocurrent linearity. The upper limit is defined as a point where the photocurrent output deviates
10 % from the linearity.
