172 EE-SF5(-B) Photomicrosensor (Reflective)
Photomicrosensor (Reflective)
EE-SF5(-B)
Dimensions
Note: All units are in millimeters unless otherwise indicated.
Features
Dust-tight construction.
With a visible-light intercepting filter which allows objects to be
sensed without being greatly influenced by the light radiated from
fluorescent lamps.
Mounted with M2 screws.
Model with soldering terminals (EE-SF5).
Model with PCB terminals (EE-SF5-B).
Recommended sensing distance = 5.0 mm
Absolute Maximum Ratings (Ta = 25°C)
Note: 1. Refer to the temperature rating chart if the ambient temper-
ature exceeds 25°C.
2. The pulse width is 10 μs maximum with a frequency of
100 Hz.
3. Complete soldering within 10 seconds.
Electrical and Optical Characteristics (Ta = 25°C)
Note: The letter “d” indicates the distance between the top surface of the sensor and the sensing object.
