| Technical/Catalog Information | QCK3 |
| Vendor | Fairchild Semiconductor |
| Category | Sensors, Sensor Evaluation Kits |
| Lead Free Status | Lead Free |
| RoHS Status | RoHS Compliant |
| Other Names | QCK3 QCK3 |
The QCK3/QCK4 is a slotted optical switch 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 otheracross a .157-inch (4.0 mm) gap. The leads are formed to sit flush on a PCB during solder reflow.
