Technical Data and Specifications
E68 Series Integral Sensor Valve
Optical Performance
All optical specifications
are guaranteed to be the
minimum performance
under clean conditions of
any product delivered from
stock. Typical performance
may be higher.
Dirt in the environment will
affect optical performance by
reducing the amount of light
the control receives.
For best results, sensors
should be used at distances
where excess gain is higher
than 1.5 (1.5 times the
amount of sensing power
required to detect an object
under ideal conditions).
Higher excess gain will allow
the sensor to overcome
higher levels of
contamination on the lens.
Polarized Reflex Diffuse Reflective
Notes
1
Output will reset automatically when short is removed (there is no visual indication of a short-circuit condition).
2
