 0.125” (3.18 mm) slot width 

 0.320” (8.128 mm) lead spacing for PCBoard (side mounting)  Data rates to 250 kBaud 

The **OPB930** and **OPB940** series of Photologic® photo integrated circuit switches provide optimum flexibility for the design engineer.  Building from a standard housing with a 0.125” (3.18 mm) wide slot, a 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 (for applications where aperture contamination may occur) or opaque plastic (for maximum protection against ambient light). 

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. 

Custom electrical, wire and cabling and connectors are available.  Contact your local representative or OPTEK for more information.

## Notes: 

(1) RMA flux is recommended.  Duration can be extended to 10 seconds maximum when flow soldering. 

(2) Derate linearly 2.22 mW/°C above 25°. 

(3) Derate linearly 4.44 mW/°C above 25°. 

(4) Derate linearly 6.66 mW/°C above 25°. 

(5) OPB930L/OPB940L series devices are terminated with 0.020” square leads designed for PCBoard mounting. 

(6) Methanol and isopropanol are recommended as cleaning agents.  Plastic housing is soluble in chlorinated hydrocarbons and ketones. (7) All parameters tested using pulse technique.

## **Wired (W) version** 

The W Series includes wire terminations of 24” (610 mm) 7-strand, 26 AWG UL insulated wire on each terminal.  Each  device incorporates a wire strain relief at the housing surface.  The insulation functions and colors are:  anode (red), cathode (black), phototransistor collector (white) and phototransistor emitter (green).

Notes: 

(1) Normal application would be with light source blocked, simulated by IF = 0 mA. 

(2) All parameters are tested using pulse techniques.
