The OPB940 (L and W) series Photologic� Photo Integrated Circuit Switches that provide optimum flexibility for the design engineer. Building from a standard housing with a wide slot, user can specify the type and polarity of TTL output, discrete shell material, aperture width and either 0.350" (8.9 mm) long pins (L series) or 24" (610 mm) AWG, UL listed wire leads (W series). All housings are made from an opaque grade of injection-molded plastic that minimizes the assembly's sensitivity to both visible and near-infrared ambient radiation. Discrete shells (exposed on the parallel faces inside the device throat) are either IR transmissive plastic or opaque plastic. Electrical output can be specified as either TTL Totem Pole or TTL Open Collector, either of which can be supplied with buffer or inverter output polarity. All devices have the added stability of a built-in hysteresis amplifier.
- Choice of aperture size
- Choice of output configurations
- Choice of opaque or IR transmissive shell material
- Choice of pins (L) or wires (W)
- 0.125" (3.18mm) Slot width
- 0.320" (8.128mm) Lead spacing for PCB (side mounting)
- Data rates to 250kBaud

Country Archer Beef Jerky Sticks: A Clean, High-Protein Snack with Bold Flavor
Flavor Name: Original, Size: 1 Ounce (18 Count), Flavor Name: Original, Size: 1 Ounce (18 Count)
Country Archer Beef Jerky Sticks are a fantastic option for anyone looking for a flavorful, high-protein snack. With around 6-7 grams of protein per stick and only 70-80 calories, they’re a great choice for those trying to keep their snack game healthy while maintaining a balanced diet. What sets Country Archer apart is their commitment to using clean, natural ingredients, without artificial preservatives or added nitrates, which makes them a cleaner option compared to many other jerky brands.
The texture is tender yet satisfying, and the flavor is bold without being too overpowering. The jerky sticks are slightly on the pricier side, but if you're prioritizing quality and natural ingredients, it's well worth the investment. While they still have a bit of sodium, they tend to have less than some other jerky options, making them a good fit for those keeping an eye on their salt intake.
Overall, Country Archer Beef Jerky Sticks are an excellent, convenient snack that delivers on taste, protein, and clean ingredients—ideal for anyone looking for a healthy and satisfying option on the go.
