W5_Z= 26 AWG wire termination (24” [61cm] long)
Features:
• 0.375” (9.5 mm) wide gap
• Choice of logical output configurations
• Choice of opaque or IR transmissive housing material
• Choice of PCBoard or 26 AWG, UL rated wire
• Data rates to 250 kBaud
Description:
The OPB900 - OPB913 series of Photologic® Integrated Circuit Switches provide optimum flexibility for the design
engineer. Building from a standard housing with a 0.375” (9.5mm) wide slot, a user can specify the type and
polarity of the TTL output and the type of shell material.
Electrical output can be specified as either TTL Totem Pole (buffered) or TTL Open Collector, either of which can
be supplied with an inverted output polarity.
All versions have the added stability of hysteresis built into the amplification circuitry.
