unless otherwise specified.
3. All leads are coplanar within .006".
4. Housing material is electrically conductive.
DESCRIPTION
The QCK3/QCK4 is a slotted opticalswitch designed for surface mount applications where extreme temperatures are experienced
during solder reflow. The switch consists of a GaAs LED and a silicon photodarlington facing each other across a.157" (4.0 mm)
gap. The leads are formed to sit flush on a PCB during solder reflow.
FEATURES
• Unique single piece housing designed to reduce cost.
• High temperature housing material to withstand extreme temperature.
• Shipped in plastic tubes for protection of leads and to feed automatic placement equipment.
• Sensor package is infrared transparent and tinted to attenuate visible light.
