Frequently Asked Questions (FAQ)
Q: Can OPB983T55Z be directly replaced with OPB983T51Z? A: Yes. Both parts share identical electrical specifications, sensing distance, output configuration, supply voltage and current requirements, response time, operating temperature range, and mounting type. The parts are mechanically and electrically interchangeable.
Q: What is the difference between OPB983 and OPB933 base product families? A: Both families are part of the Photologic® series and share identical electrical and mechanical specifications as listed in the parameter comparison table. Substitution between families is valid based on matching all critical parameters.
Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance certification and REACH unaffected status.
Q: Does the part number suffix affect substitutability? A: Substitutability is determined by the electrical specifications, sensing distance, output configuration, supply requirements, response time, operating temperature range, and mounting type. All listed parts match these criteria and are therefore equivalent.
Q: What is the sensing distance specification for this optical sensor? A: The sensing distance is 0.125" (3.18mm) for all listed parts, indicating the maximum distance at which the through-beam sensor can detect an object interrupting the optical path.
Q: Can these sensors operate outside the -40°C to 70°C temperature range? A: No. All listed parts are specified for operation within -40°C to 70°C. Operation outside this range is not supported.
Q: What output configuration does this sensor provide? A: The OPB983T55Z and all substitute parts provide NPN open collector inverted output configuration, meaning the output is low when an object is detected and high when no object is present.
