Optek Through Hole Slotted Optical Switch, Phototransistor Output

OPB610, OPB611, OPB620 and OPB621 Series Slotted Optical Switches

This family of slotted optical switches, from Optek Technology, are designed to be mounted onto a PCB.
The OPB610 and OPB620 consist of an IR LED and an NPN silicon phototransistor. They have an enhanced low current roll-off which improves the contrast ratio and block out ambient light.
The OPB611 and OPB621 consist of an IR LED and a PIN photodiode. Their plastic housing is opaque to visible light but transmissive to IR light. The PIN photodiode within these slotted optical switches is ideal for use in high-speed operation.
Suitable applications for the slotted optical switches include; non-contact reflective object sensors, assembly line automation, machine automation, machine safety and door sensors.
