Optical Type
   Technology       
   Your choices are...         
   Through Beam       Through beam (or opposed mode) sensors incorporate a transmitter and a receiver on opposite sides of the target and evaluate absence or presence based on transmittance or blockage of the beam respectively. 
   Retroreflective       This design incorporates the emitter and detector in one body with parallel beams; a reflector opposite the target path is used to reflect the emitted beam back to detector; presence is detected when reflected beam is interrupted by an opaque object. 
   Polarized Retroreflective       Variant of the retroreflective in which the emitter and receiver have polarizing filters 90º apart, thereby making the reflector the only recognizable source.  This is used to prevent false detection from sources other than reflector. 
   Diffuse       Emitter and receiver are packaged together. Presence is detected when any portion of the diffuse reflected signal bounces back from the detected object. Reflective properties of the target must be evaluated for correct placement. 
   Divergent       Divergent beam sensors are short-range diffuse-type sensors without any collimating lenses.  This makes the presentation angle of the target less critical.  This is important for mirror-like or specular objects, where a collimated beam from a standard diffuse sensor may reflect off a non-parallel surface and may thus not be detected.  This type can also be used for short-range sensing of targets with small profiles such as wire or yarn. 
   Convergent       Convergent, fixed focus, or fixed distance. Optics (such as lenses) are used to focus the emitter beam at a fixed distance from the sensor. Another lens may be used to focus the field of view of the receiver on exactly the same spot. This allows for good sensitivity but limited depth of detection. The high sensitivity of this style makes it suitable for uses such as detection of transparent objects. 
   Fixed Field Background Suppression       Fixed-field sensors are designed to have a distance limit beyond which they will not detect objects, no matter how reflective.  This is done with an emitter and two detectors, whose light detection is compared.  Sensor output is canceled when light detection by one detector surpasses the other.  The field distance is typically factory set per application specifications. 
   Adjustable Field Background Suppression       Adjustable field sensors utilize a cutoff distance beyond which a target will not be detected, even if it is more reflective than the target.  Two current outputs from the sensor are compared to indicate detection.  The ratio of the two currents determines the cutoff distance and is readily adjustable, electronically or with a manual adjustment such as a potentiometer.

   Fiber Optic       
   Your choices are...         
   Glass       Light is supplied and returned via glass fiber optic cables.  Fiber optic cables can fit in small spaces, are not susceptible to electrical noise, and exhibit no danger of sparking or shorting.  Glass fiber exhibits very good optical qualities and typically carries high temperature ratings. 
   Plastic       Light is supplied and returned via plastic fiber optic cables.  Fiber optic cables can fit in small spaces, are not susceptible to electrical noise, and exhibit no danger of sparking or shorting.  Plastic fiber can be cut to length in the field and can be flexible enough to accommodate various routing configurations.

Electrical
   Output       
   Your choices are...         
   Voltage       Output voltage is a simple (usually linear) function of the measurement. 
   Current       Often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals long distances. 
   Frequency       The output signal is encoded via amplitude modulation (AM), frequency modulation (FM), or some other modulation scheme, but the signal is still analog in nature. 
   Resistance       An output consisting of a simple change in resistance is typically for a magnetoresistive device. 
   Switched / Alarm       An "output" of a change in state of switches or alarms
