American Bright Introduces Miniature Photo Interrupter Group Featuring Miniature Connectorized & Actuator Assemblies

Absolute detection refines high-speed application uses with choice of function and package styles; units are manufactured Pb-Free (RoHS) compliant

Chino, CA, September 30, 2005 - American Bright Optoelectronics has announced their new Photo Interrupter family, designed for use in IR/optical detection applications such as copiers, printers, high-speed industrial machinery, garage door openers and photo encoder based devices. Featuring high precision optics, and a variety of gate widths, these miniature devices are excellent alternatives to the use of conventional switches, which may demonstrate backlash or delays in detection speed and accuracy. They function comfortably in either analog or digital control techniques, and provide non-contact detection, long-life, low power consumption, high reliability and high precision.

The BPI Series offers a choice of twenty-four (24) Slotted types, seven (7) Actuator, and five (5) Reflective types, including mini-reflective models available in axial and gull-wing packages. Highlighting the new group, several miniature models are featured in harnessed/connectorized styles, providing a "plug-n-play" unit for replacement and lower installation cost. Actuator types include levered operation in device packages as small as 0.374" (9.5mm) x 0.394" (10.0mm) from base unit to optic line. Light beam interruption of the actuator units range from 0.35VOL (@IOL=16mA). Forward voltages (VF) of slotted types range from 1.5V maximum (@IF=20mA), IR of 100µA (@VR=5V), and gap widths from 0.125 (3.18mm). Encoder styles feature two-bit PTR and dual-channel OEIC (Rambo OEIC) functions. And, custom functions and packaging is available.

"By offering the complete infrared and OPIC solution, we can create added value to the engineering decision to use these devices for added accuracy and packaging needs", stated George Lee, American Bright President. He added, "Our PI assemblies can significantly lower installed unit costs for the OEM."

In addition to the photo interrupter product group, American Bright also offers a complete selection of complimenting IR products, including diodes, phototransistors, photodiodes, receiver modules, photolink transmitters and receivers, and high sensitivity OPIC Schmidt trigger circuit devices. All configurations are manufactured in compliance with Pb Free (RoHS) materials and processes.

The BPI Series is priced from $0.15 per piece, and start at $0.30 each for the BPI Series with PCB assembly in production quantities and are immediately available from stock. For modified or custom packaging or assembly requirements, contact the factory. For complete specifications, visit or call Toll Free (888) 533-0800.
