Sensing range / Distance to convergent point - Glossary - Photoelectric Sensors

Sensing range / Distance to convergent point

Thru-beam type

The distance which can be set between the emitter and the receiver under the stable sensing condition.
(The abbreviation "0～" is set for values starting from 0.)

Retroreflective type

The distance which can be set between the emitter and the receiver under the stable sensing condition.
(The abbreviation "0～" is set for values starting from 0.)

Reflective type

The distance which can be set between the sensor and the standard sensing object (normally, white nonglossy paper) under the stable sensing condition.
(The abbreviation "0～" is set for values starting from 0.)

Distance to convergent point

With the convergent reflective type sensor or the mark sensor, sensitivity is not proportional to the setting distance and the maximum sensitivity point is at an intermediate position.
This point at which the sensitivity is maximum is called the convergent point and is specified along with the sensing range.
