The OPB960 and OPB970 series of Photologic Photo Integrated Circuit Switches provide optimum flexibility for the design engineer. Building from a standard housing with a .125” wide slot, the user can specify (1) type and polarity of TTL output, (2) discrete shell material, (3) aperture width, and (4) type of mounting configuration. Available with 24”, 26AWG wire leads as OPB980/OPB990 series.
The OPB960 and OPB970 series provide optimum flexibility for design engineers. Users can choose mounting configuration, aperture width, shell material (opaque or IR‑transmissive), and TTL output type (totem‑pole or open‑collector) with optional inverter or buffer polarity. All devices include a built‑in hysteresis amplifier for added stability.
Electrical specifications include supply voltages of 4.75‑5.25 V, input diode forward voltage of 1.7 V, reverse current of 100 µA, and output voltage levels of 0.4 V (low) and 2.4 V (high). The switches operate from –40 °C to +70 °C and can be stored from –40 °C to +85 °C. They feature .020" square leads for PCB mounting and are housed in opaque or IR‑transmissive plastic packages.
