TT Electronics Slotted Switch, Transistor; Sensor Output Tt Electronics/optek Technology OPB620

The OPB620 is a slotted optical switch with a printed circuit board mounting style, consisting of an infrared emitting diode and an NPN silicon phototransistor. It has a slot width of 0.190 inch and lead spacing of 0.320 inch. The device operates with a maximum collector-emitter voltage of 24 V, collector DC current of 30 mA, and power dissipation of 200 mW. The infrared LED has a peak wavelength of 890 nm and a forward voltage of 1.6 V at 10 mA. The phototransistor has a collector-emitter dark current of 100 nA at 5 V. The package is opaque to visible light but transmissive to infrared, and the part is RoHS compliant.
