SPECIFICATIONS
Sensor heads
Notes: 1) Where measurement conditions have not been specied precisely, the conditions used were an ambient temperature of +23 °C +73.4 °F.
2) The sensing range and the hysteresis of the diffuse reective type sensor are specied for white non-glossy paper (50 × 50 mm 1.969 × 1.969 in) as the
object.
3) Make sure to conrm detection with an actual sensor before use.
4) The optimum condition is the condition when the sensitivity is adjusted so that the operation indicator just lights up at the given distance in the light
received condition.
5) The optimum sensitivity stands for the sensitivity level when the operation indicator just lights up in the light received condition.
