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.

Very nice but truly slim fit
Color: Sky Blue, Size: 2
Nice fabric and style. True to its title- this is a Slim fit suit, so the jacket is cut more narrow and a little longer.

Great spring or summer fit
This came a little bigger than anticipated, but other than that, this is a great quality set. It's a little lighter, which is great for spring or summer. The color is just as pictured and I'm impressed with the altogether fit.
