Description:
Each
OPB827, OPB828
and
OPB829
device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a
NPN silicon phototransistor, mounted on opposite sides of a 0.125” (3.18 mm) wide slot in a low-cost black plastic housing.
A variety of aperture sizes are offered (see chart below). The
OPB827
and
OPB828
are designed fro PCBoard mounting with
a minimum lead length of 0.35” (8.9 mm) while the
OPB829Z
(wire version) has 24-inch 26 AWG wire leads. Phototransistor
switching occurs when an opaque object passes through the slot.
The
OPB827
is offered with 0.305” (7.75 mm) and the
OPB828
is offered with 0.220” (5.59 mm) lead spacing for PCBoard
mounting. The
OPB829Z
has 24” (61 cm) 26 AWG wire leads for remote mounting.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more
information.

To avoid stress cracking, we suggest using
ND Industries’
Vibra-Tite
for thread-locking.
Vibra-Tite
evaporates fast without causing structural
failure in OPTEK’s molded plastics.
Applies to: OPB360, OPB370, OPB380, OPB390
and OPB860, OPB870, OPB880, OPB890.
