Slotted Optical Switch OPB819Z Features: Non-contact switching 24” (609 mm) long wire leads 1.25” ( 31.75 mm) wide slot, 1.38” (35.05 mm) deep slot Description: The OPB819Z slotted switch consists of an infrared emitting diode and an NPN silicon phototransistor mounted in an opaque housing with clear windows for dust protection. Switching of the phototransistor occurs whenever an opaque object passes through the slot. The OPB819Z has an 1.38” (35.05 mm) deep and 1.25” (31.75 mm) wide slot allowing for a longer reach of the optical center line from the mounting plane. The switch housing is designed to use the lens of each component as the optical aperture resulting in an equivalent aperture diameter of 0.06” (1.52 mm). Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information. Color Applications: Non-contact object sensing Assembly line automation Machine automation Equipment security Machine safety ANODE CATHODE Description Color Description Red Anode White Collector Black Cathode Green Emitter COLLECTOR EMITTER Ordering Information RoHS Part Number LED Peak Wavelength OPB819Z 890 nm Sensor Slot Width / Depth Transistor 1.26" / 1.38” Aperture Emitter/ Sensor Lead Length / Spacing None 24" / 26 AWG Wire CONTAINS POLYSULFONE 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.

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. Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and ketones. Spray and wipe. Do not submerge. Polarity is denoted by color the wires: LED (Anode—Red, Cathode—Black); Phototransistor (Collector—White, Emitter—Green).
