This document discusses the quality assurance and reliability of sensors, including important considerations in the design, manufacturing, and sales processes. It mentions the lifespan of infrared LEDs and the changes in output power over time. The document also covers two broad categories of reliability testing: life testing and environmental testing. It states that ROHM has standardized its procedures to comply with Japan Industrial Standards (JIS) and American military standards (MIL).
The document outlines ROHM's approach to ensuring high‑quality sensor products, describing the processes used for quality assurance and the importance of designing with sufficient margin for component life, especially infrared LEDs.
It also details the two main categories of reliability testing—life testing and environmental testing—and notes that ROHM follows Japan Industrial Standards (JIS) and American military standards (MIL). An appendix provides usage warnings and export control information.
ROHM follows Japan Industrial Standards (JIS) and American military standards (MIL).
Design with sufficient margin to allow for the LED’s output power loss over time.
