SMARTEYE® MARK II

Smarteye Mark II

Features high-gain combined with very high-speed. These high performance sensors were designed to resolve the most difficult sensing tasks...the hallmark of all TRI-TRONICS SMARTEYE^® sensors. In addition to superior high gain/high speed, the MARK II is equipped with many new improvements such as EDR® (Enhanced Dynamic Range). EDR® eliminates dark-state saturation that can dramatically reduce sensor resolution. NPN and PNP outputs and a switch to set light or dark operate are included. Fully encapsulated this sensor will withstand harsh environments.

EDR^® Enhanced Dynamic Range
(Patent No. 5,621,205)
The EDR^® circuit extends the dynamic operating range to provide unequaled performance at very bright light levels. Dynamic operating range has been extended 500X to eliminate the effects of background suppression which can cause reduced resolution. To avoid saturation and enhance background suppression, the EDR^® circuit monitors the offset adjustment during setup to determine when the sensor’s operating level is approaching the sensor’s light level saturation point. Before saturation occurs, the EDR^® circuit adjusts the sensor in such a unique manner so as to prevent saturation and extends the overall dynamic range of the SMARTEYE^® MARK II sensor.

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.

HIGH-RESOLUTION & HIGH-SPEED
High resolution and speed combined. Can be used in vertually 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.

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.

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.

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.

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.
