Unique pulse modulated Photoelectric Sensors that has successfully performed hundreds of intricate “low contrast” sensing tasks in critical material handling and automation applications. This versatile sensor has set the “standard of performance” in the photoelectric sensing of size, texture, distance, opacity, depth and even color. With SMARTEYE^®, there is no question whether it will perform the task, because it will do the job with “performance to spare.”

THREE PERFORMANCE LEVELS
High Speed Models: SD, PSD (recommended for most sensing tasks)
Excellent resolution and high-speed response. 500µs Beam Make or Beam Break. Maximum input events per second =1000. Optimized to provide a balance between high speed of response and performance to match moderate to low-contrast applications typically found in high-speed automation.
High Gain Models: HSD, PHSD (recommended for very low contrast applications)
Highest resolution. 1.5ms Beam Make or Beam Break. Maximum input events per second = 333. High amplification enables sensor to respond to very low contrast applications found in the more difficult sensing tasks. High gain is often necessary to perform product inspection or orientation sensing tasks.
Very High Speed Models: VSD, PVSD (recommended only when high-speed sensing is critical)
Good resolution and very high-speed response. 100µs Beam Make or Beam Break. Maximum input events per second = 5000. Optimized to provide very high speed response while maintaining the necessary performance levels required in high velocity/high speed sensing.

4-TURN OFFSET ADJUSTMENT
Offset vs. gain adjustment maintains sensor high resolution performance regardless of threshold position. Resolving fine differences in returned light increases stability and versatility of the sensor. A 4-Turn potentiometer makes it easy to set the sensor to the right threshold setting.

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.

Contrast is a comparison of the lightest state reading vs. the darkest state reading. The sensing task of any digital (switching) photoelectric sensor is to resolve the difference between these two light levels and switch the output accordingly. The SMARTEYE^® switches its output when the light level passes the mid-scale reading of “5.”

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.

High Intensity Infrared Light Source
Invisible light for maximum possible range in either Beam Make or Beam Break sensing modes. Provides maximum penetration for use in harsh environments. Also works well with the small diameter fiberoptic light guides. NOTE: Not recommended for use in close-up sensing or for use in most low contrast applications.

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.

Green (Visible) Light Source
Recommended for use only in applications where the color green provides an obvious advantage. An example would be sensing a light colored red/pink object on a white background. Also has been used in film processing applications when red or infrared light can cause damage to sensitive film.

Type F1 Fiberoptic Adapter	Type R1 Retroreflective	Type O1,O1G Medium to Long Range Proximity	Type O2 Short Range Proximity	Type V1/V1G Focused Lens "V" Axis
Type F1 adapts sensor to any standard fiber optic light guide with .187" O.D. tips. The light guide is inserted and held in place with a slide-action snap.	Type R1 turns the sensor into a retroreflective sensor. Range is dependent on model of the MARK II selected and size of reflectors.	Type O1, O1G (glass) adapts the sensor to the optical proximity mode of sensing. Range is dependent on size, shape, surface reflectivity of the object to be detected.	Type O2 also adapts the sensor to the optical proximity mode of sensing, but on a sharp “V” axis to control depth of view. Range is dependent on model of the sensor selected.	Type V1, V1G (Glass) is for direct lens “V” axis sensing at close ranges. Used for small part or precise leading edge sensing. Range is dependent on model of the sensor selected.
