Photoelectric Sensors 42FT Visible Red or Green Plastic Fiber Optic

The 42FT is a compact, DIN Rail
mount fiber optic photoelectric sensor
with sophisticated part detection,
diagnostic, and self-teach capabilities.
Five LED indicators provide
diagnostic and alignment information.
A dynamic diagnostic output signals
when margin levels are below a
predetermined threshold for seven
successive detections.
The self-teach capability allows the
Bulletin 42FT to determine an
optimum sensitivity and hysteresis
setting for a specific application. The
remote lockout feature can be used to
help prevent unauthorized changes to
these adjustments. A switch
selectable 50 ms off-delay ("pulse
stretcher") is useful in high speed
applications where the output pulse
must be lengthened to allow time for
the machine logic to respond.
