Non-contact reflective object sensor delivers reliable performance

22-03-2021 | TT Electronics | Test & Measurement

TT Electronics has announced its new OPB735 series Reflective Object Sensors for very challenging industrial automation and safety applications. This reflective sensor provides hermetically sealed components giving designers a broad operating temperature range of -55C to 100C to satisfy almost any factory setting. Created to provide extremely low cross-talk or noise signal, this product gives users reliable and consistent performance in even the most challenging applications.


“With the OPB735, TT is responding to increased demand for reliability and consistency in industrial automation applications,” said Walter Brooks, global product line manager, Optoelectronics at TT Electronics. “The sensor’s low-profile design, along with its broad operating temperature range and hermetically sealed components, gives designers an exceptional reflective solution that can be used in multiple places within the same system for maximum effect.”


Designers can select between phototransistor or photodarlington output to satisfy specific needs or parameters; in either option, the detector reacts to radiation from the IRED only when a reflective object passes in its field of view. The series is encased side-by-side on converging optical axes in a low-cost, black thermoplastic housing. The OPB735XWZ variation comprises UL 1569 approved #28 AWG lead wires. Custom electrical, wire cabling and connectors options are also offered.
