DARK-ON
An operating mode that allows the sensor head to output an ON signal when the prescribed light quantity, or more, is blocked by the target.Decibel
A unit used to express the change in amplitude or the level of sound. As a unit, it is written as dB. Decibels are calculated as 20log (V1/V2) for voltage (current) signals, and as 10log (V1/V2) for other signals.Delta-sigma A/D Conversion Method
The delta-sigma A/D conversion method is a combination of oversampling and integration to achieve more accurate A/D conversion than conventional common methods (sequential conversion method or flash conversion method).Depth-of-field
A lens with a large depth-of-field, allows even odd-shaped objects to be brought into focus.Detecting distance
The distance from the detecting surface of a sensor head to the point where a standard target approaching the sensor head is first detected. Maximum operating distance (ES Series): The maximum obtainable operating distance, disregarding accuracy.Detecting distance - Reflective types
The maximum distance from the sensor head to a standard target that permits the sensor head to stably detect a light beam reflected from the standard target.Detecting distance - Retro-reflective type
The maximum distance from the transmitter to the receiver that permits the receiver to stably receive reflected from the reflector.Detecting distance - Thrubeam type
The maximum distance from the transmitter to the receiver that permits the receiver to stably receive a light beam emitted from the transmitter.Detection Range
It means the rated range of FD. The detection range is 10 to 100% of F.S.Differential Balanced Input
A differential input of which the positive and negative sides of the input circuit are the same circuit.<=> Imbalanced input
