What's the difference between a Reflective Fiber Unit and a Coaxial Reflective Fiber Unit?
The sensing surfaces of the Fiber Units differ as shown below. Each is used for a different type of application.
The differences in the sensing methods are given in the following table.
|Sensing method||Features and other information|
(E32-DC200 and others)
|Used for detecting the presence of ordinary workpieces.|
Various Sensing Head shapes, sensing distances, etc., are available for specific
The operating range depends on the set direction (see note) of the Fiber Head.
|Coaxial reflective models|
|Used for workpiece positional detection.|
The operating range depends on the set direction of the Fiber Head.
(This is because a fiber for the Receiver is placed near the fiber for the Emitter.)
Models other than the E32-CC200 and E32-D32L can be used as a small-spot
reflective models when combined with a small-spot lens (E39-F3A, E39-F3A-5,
E39-F3B, and E39-F3C).
Note:The set directions for the Fiber Head are and .
