| :: Diffuse Scan Photo Sensor |
Diffuse Photo
Sensor recognize the presence of target at a preset
distance from optical face & available in cylindrical &
flat shape. In diffuse scan photo sensor Emitter & Receiver
in same housing.
In diffuse scan photo sensor emitter E sends out a beam of infraded
which reflected directly by target (at any angle) to the receiver
R. The receiver receive a small portion of light switching the
sensor when target detected in effective sensing range.

|
| :: Retro Reflective Photo Senser |
It recognize
the presence of target independent of color and surgace properties.
In retro reflective sensor Emitter & Receiver in same housing.
In Retro Photo Sensor emitter E sends out a
beam of infraded light which reflected by triple prism reflector
directly to the receiver R. When any object interrupt the light
beam the output of sensor changed. |
|
| :: Through Beam Type Photo Sensor |
| In Through
Beam Type Photo Sensor emitter & receiver in different
housing & placed to each other at 90 degree in conjunction
with the control unit having relay changeover contacts. In
through Beam Sensor emitter S sends out a beam of infraded
light & directly receive by receiver E. When any object
interrupt the light beam the output of sensor changed. |
