Reflective Object Sensor

OPB606A, OPB606B, OPB606C

OPB607A, OPB607B, OPB607C

Features:

(OPB607) output

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.

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.
