Description:
OPB606 consists of an infrared Light Emitting Diode (LED) and an NPN silicon phototransistor which are mounted "side-by-side" on parallel axes in a black opaque plastic housing. The OPB607 consists of an infrared Light Emitting Diode (LED) and an NPN silicon photodarlington which are mounted "side-by-side" on parallel axes in a black plastic housing. The emitting diode and phototransistor of both the OPB606 and OPB607 are encapsulated in a filtering epoxy that reduces ambient light noise. On both models, the phototransistors respond to radiation from the emitter only when a reflective object passes within the field of view. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
Applications:
* Non-contact reflective object sensor * Assembly line automation * Machine automation * Machine safety * End of travel sensor * Door sensor

To avoid stress cracking, we suggest using ND Industries' Vibra-Tite for thread-locking. Vibra-Tite evaporates fast without causing structural failure in OPTEK's molded plastics.

Notes: (1) "d" is the distance from the assembly measurement surface to the reflective surface. (2) Measured using Eastman Kodak neutral white test card with 90% diffuse reflectance as a reflecting surface. Reference: Eastman Kodak, Catalog #1257795. (3) On OPB606, off-state collector current IC(OFF) is measured with no reflective surface in the optical path. On OPB607, Crosstalk (Icx) is the collector current measured with the indicated current in the input diode and with no reflecting surface. (4) All parameters tested using pulse techniques.
