Since introducing the SMARTEYE® line, these unique pulse modulated Photoelectric Sensors have successfully performed hundreds of intricate “low contrast” sensing tasks in critical material handling and automation applications— including product inspection tasks where even $5,000 and $10,000 vision systems couldn’t do the job!

In fact, the versatile SMARTEYE® 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 SMARTEYE® will do the job with “performance to spare.”

High-speed response, high sensitivity, and long-range capabilities, combined with the unique CONTRAST INDICATOR give you a sensor that you can depend on — a sensor that eliminates marginal performance — and all at an affordable price!

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 midscale reading of “5.”

FIBEROPTIC LIGHT GUIDES

Flexible fiberoptic light guides are available in sizes small enough to fit into the toughest job sensing sites. There are many models available for inaccessible areas such as extremely tight mechanical pockets, high temperature applications, corrosive or caustic environments, or high vibration mounting considerations. There are many varieties of tip configurations available for either straight or bifurcated fiberoptic requirements.

Features

PERFORMANCE

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 highspeed 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 in SMARTEYE®s used 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.

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.
