OPB829Z
Description:
Each OPB827, OPB828 and OPB829 device consists of an infrared emiꢃng 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 plasꢂc housing.
A variety of aperture sizes are offered (see chart below). The OPB827 and OPB828 are designed fro PCBoard mounꢂng 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
mounꢂng. The OPB829Z has 24” (61 cm) 26 AWG wire leads for remote mounꢂng.
Custom electrical, wire and cabling and connectors are available. Contact your local representaꢂve or OPTEK for more
informaꢂon.

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 plasꢂcs.
Applies to: OPB360, OPB370, OPB380, OPB390
and OPB860, OPB870, OPB880, OPB890.
