1) WHAT IS THE DIFFERENCE BETWEEN COMMERCIAL-GRADE AND INDUSTRIAL-GRADE PRODUCTS?
Answer: The major difference between commercial-grade and industrial-grade electronic components is the operating temperature range. Otherwise, the quality standards to which the components are manufactured are the same. Commercial-grade components typically have an operating temperature range of –4 degrees F. to 140 degrees F. (-20C. to 60C.), whereas industrial-grade components are designed for a substantially wider operating temperature range, typically –40 degrees F. to 140 degrees F. (-40C to 85C). Commercial-grade components are a good choice for use in benign environments, such as that found in an indoor office. Industrial-grade components should be used in environments subject to wider ambient temperature variations, such as those found outdoors, in non-environmentally controlled structures, or on a factory floor. In addition, industrial-grade electronics may offer further features such as improved signal sensitivity, or greater tolerance to electrical noise.
