Reflective Object Sensor KW710, KW710&, KW730, KW730&
The KW710 series reflective object sensors are designed for non-contact object detection. These sensors utilize a gallium arsenide infrared emitting diode paired with either a silicon phototransistor (KW710/KW710&) or a silicon photodarlington (KW730/KW730&). They are housed in a standard TO-72 header with a black plastic sleeve filled with encapsulating epoxy. The "F" versions (KW710F/KW730F) incorporate a filtering material to reduce ambient light interference. An internal barrier prevents direct diode emission from reaching the sensor. Custom electrical, wire, cabling, and connector options are available.
Applications:
- Non-contact reflective object sensor
- Assembly line automation
- Machine automation
- Machine safety
- End of travel sensor
- Door sensor
Features:
- Choice of phototransistor or photodarlington output
- Unfocused for sensing diffuse surfaces
- Mounted on standard TO-72 header
- Available in clear encapsulating epoxy (KW710, KW730)
- Filtered to reduce the effect of visible or fluorescent light (KW710F, KW730F)

Combined Notes:
- (1) RoHS flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
- (2) Derate linearly 1.67 mW/C above 25C.
- (3) Derate linearly 3.33 mW/C above 25C.
- (4) Measured using Eastman Kodak neutral white test card having 90% diffuse reflectance located 0.250 inches (6.35 mm) from the face of the KW710/KW730. Reference: Eastman Kodak, Catalog #1527795.
- (5) Crosstalk (IX) is the collector current measured with the indicated current on the input diode and with no reflecting surface. Ambient light is excluded with a black box.
