Slotted Optical Switch
OPB819Z
Features:
•
Non-contact switching
•
24” (609 mm) long wire leads
•
1.25” ( 31.75 mm) wide slot, 1.38” (35.05 mm) deep slot
Description:
The
OPB819Z
slotted switch consists of an infrared emitting diode and an NPN silicon phototransistor mounted in
an opaque housing with clear windows for dust protection. Switching of the phototransistor occurs whenever an
opaque object passes through the slot.
The
OPB819Z
has an 1.38” (35.05 mm) deep and 1.25” (31.75 mm) wide slot allowing for a longer reach of the
optical center line from the mounting plane. The switch housing is designed to use the lens of each component as
the optical aperture resulting in an equivalent aperture diameter of 0.06” (1.52 mm).
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.
