Sensing height (Protective height) - Glossary - Photoelectric Sensors
Sensing height (Protective height)
This represents the range within which sensing objects can be detected for the light curtain and area sensor.
The conventional light curtain [SF2-EH series (discontinued product)] and area sensor has a sensing height (protective height) limited to the height from the bottommost end beam axis to the topmost end beam axis.
Example: in the case of a 20 mm 0.787 in beam pitch
<SF4B(-01) (Note) / SF2B series / SF4C series>
Sensing height (protective height) is the same length as the light curtain body.
(e.g.) SF4B-H12
|
| Notes : | SF4B-01 series are used for purposes other than for press in Japan. |

| * | Refer to "Definition of light curtains and area sensor sensing heights" for sensing height of other light curtains and area sensors. |
