Application Example (1-08)
Sanitary Equipment A

• ・Start the equipment automatically not by touching it but by sensing the hand.

• ・Want to change the switch to the touchless type from the viewpoint of sanitation and adopt an easy-to-clean structure.
• ・Want to ensure detection of the palm by the sensor.
• ・Want to eliminate the sensor’s malfunction due to external disturbing light.

• ・Adopted model:
  Light convergent reflective sensor B5W-LB2112-1
• ・This sensor is optically designed to detect objects such as specular, black, and transparent objects. Therefore, it is effective for detecting the palm.
• ・By placing a thin transparent cover in close contact with the front of the sensor to make it flat, it is possible to design equipment with a drip-proof structure that is easy to clean. See the recommended conditions for the transparent cover installation.
• ・This sensor has a function that makes it less susceptible to disturbance via light. However, it may malfunction depending on the type and intensity of the light disturbance, so install a sensor to prevent the light disturbance from entering.
