FEATURES
Non-contact type switch containing a photo sensor
The contact form is equivalent to SPST-NC, which
satisfies the PL Act.
The internal sphere can be used over an operation
angle of 360 degrees in the circumferential direction.
There are three standard terminal types
TYPICAL APPLICATIONS

2) Output (V ) characteristics (The sphere must be stationary.)
O
• V (photo transistor ON): Max. 1.0 V (horizontal)
OL
• V (photo transistor OFF): Min. 4.0 V (inclined at an angle
OH
Note: Output characteristics are the values of the applied circuit conditions,
below. Also, the microcomputer input terminals actually used use the
following voltages.
• Low level input terminal: 1.5 V or less
• High level input terminal: 3.5 V or higher
Please use with a detection method to prevent malfunction.
