Reflective Sensor OPTEK OPB760N Featuring 890 Nanometer LED and TTL Open Collector Output for Industrial
Product Description
The OPB760N, OPB760T, and OPB770T series of reflective object sensors feature Photologic output. These devices offer a choice of TTL Totem-Pole or TTL Open-Collector electrical output, with options for inverter or buffer output polarity. The OPB760N and OPB760T series are designed for PCBoard mounting with 0.04 (10 mm) leads, while the OPB760T and OPB770T series are suitable for remote mounting with two mounting tabs. The OPB770TZ series includes 12 (305 mm) long, UL approved 26 AWG wires. All devices in this series incorporate a built-in hysteresis amplifier for enhanced stability. Custom electrical configurations, wire, cabling, and connectors are available upon request.
Applications: Non-contact Photologic reflective object sensing for assembly line automation, machine automation, machine safety, end of travel sensing, and door sensing.
