Description:
Each OPB854 series contains an Infrared Light Emitting Diode (LED) and an NPN silicon phototransistor mounted on opposite sides of a 0.100" (2.54 mm) wide slot in an opaque plastic housing. The OPB854 series has an equivalent aperture of 0.60" (1.52 mm) in diameter because of the lens on the emitting an sensing devices. The difference between the OPB854A aeries and OPB854B series are electrical characteristics. Switching of the phototransistor occurs whenever an opaque object passes through the slot. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.

RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. Derate linearly 1.67 mW/C above 25 C. All parameters tested using pulse techniques. Lead spacing of 0.220" (5.59 mm) or 0.320" (8.13 mm) is available. Leads are 0.20" sq. (5.1 mm) and 0.425" (10.8 mm) long (minimum). Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and ketones. Polarity is denoted by color of housing top (gray or clear LED, black sensor).
