Powerful infrared beam reliably senses objects of low reectivity.  Ideal for count-
ing the ow of radiused products at a xed distance from the sensor. 
Focus at 1.5 in. (38mm); 
performance equal in all 
program modes.
Beam: visible red, 650nm.

HP, 2W, SP modes: 4ms
HS mode: 1ms
Repeatability: 
HP, 2W, SP= 1.3ms; 
HS = 0.3ms

Fixed-eld sensor heads have an emit-
ter element and two differently-aimed 
receiver elements.   This creates a 
high-gain sensing eld able to detect 
objects of low reectivity, and a sharp 
far-limit  sensing  cutoff  of  50mm  (2 
inches)  or  100mm  (4  inches)  which  
ignores backgrounds beyond cutoff.
These sensors are ideal for detecting a 
part or surface that is only a fraction of 
an inch in front of another surface.
RSBFFs may not be used with 2-wire 
power blocks.
