MARK III General Purpose Photoelectric Sensor

High performance photoelectric sensor in a miniature size that you can use anywhere... for any task... including your toughest industrial sensing applications. Loaded with features and benefits including high-gain and high-speed of response (50 microseconds). High-gain enables the sensor to resolve the most difficult low contrast sensing tasks. High-speed response time provides resolution of the exact position of objects traveling at high speeds.  It can either be side mounted or Din rail mounted with the universal DRB-1.  Epoxy encapsulated, it is rugged and vibration proof.

OFFSET/EDR® ADJUSTMENT
(Patent No. 5,621,205)
With the Offset/EDR® adjustment feature, the SMARTEYE® Mark III sensor can resolve very low contrast sensing tasks over a wider range of light intensities, including proper operation at high light levels. In addition, EDR® improves background suppression.

EDR INDICATOR
As the OFFSET/EDR® adjustment is rotated in the counterclockwise direction, the green EDR® indicator LED will begin to turn on and glow dimly. As the counter clock wise rotation proceeds, the intensity of the EDR® indicator will continue to increase. This indicator provides the installer an idea of just where in the overall dynamic operating range of the sensor the OFFSET/EDR<sup.® adjustment has been set.

DIN-RAIL MOUNTING
Install optional DRB1 universal mounting bracket to install on Din-Rail.

CONTRAST INDICATOR
The CONTRAST INDICATOR displays a scaled reading of the level of light received by the sensor’s photo detector. The more light received, the higher the reading. The less light received, the lower the reading.

HIGH-RESOLUTION & HIGH-SPEED 
High resolution and speed combined.  Can be used in virtually any sensing task without limits in sensing performance.

VERSATILITY
Change operating mode. Quick change” optical blocks allows one sensor to be used in proximity, convergent, retroreflective, polarized retroreflective, and fiberoptic applications.

CONNECTIONS
Built-in M12 connector for use with quick disconnect cable.

LIGHT SOURCE SELECTION

Infrared Light Source
Invisible light – recommended in opaque object sensing applications. Infrared LED light source provides long-range sensing in either Beam Make or Beam Break modes. Infrared light maximizes the sensor’s ability to penetrate contamination found in harsh environments.

Blue Light Source
Useful for detecting translucent, transparent, plastic, or glass objects in the retroreflective mode when using the R4 optical block. Used as blue filter for color perception advantages, i.e. resolving yellow vs. white colored objects or printed registration marks.

 

Red (Visible) Light Source
Visible red LED light source recommended for sensing transparent/translucent objects. Outperforms infrared light in many moderate to low contrast applications. Also recommended for use with plastic fiberoptic light guides.

White Light Source
(Broadband Color Spectrum)
The “White Light” LED light source promotes easy detection of the largest variety of color marks printed on the largest variety of colored web materials. By combining a white LED light source, our Contrast Indicator, and the one-push AUTOSET setup, you have a winning combination of high performance with an easy to use sensor.
