OPB829Z
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 OPB927 and
OPB828 are designed for 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.

• Non-contact object sensing
• Assembly line automation
• Machine automation

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.
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
