PHOTOSWITCH

Bulletin 42FT SelfĆTeach Fiber Optic

IMPORTANT: SAVE THESE INSTRUCTIONS FOR FUTURE USE.

Description

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 50ms 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.

42FT sensors are designed for DIN rail mounting. For
installation convenience, a steel mounting bracket is supplied
for separate mounting.

42FT sensors are designed for use with 2.2mm diameter
plastic fiber optic cables. An adaptor is supplied with the
sensor to use 1.25mm diameter plastic fiber optic cables. Fiber
optic cables are held in place by a rotating collar. No tools are
required to attach or remove fiber optic cables. Special glass
fiber optic cables are also available. Over 40 compatible
standard plastic and glass fiber optic cables are available,
please refer to page 1–232 of the C112 Sensor catalog.
