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
Small, Highly reliable Tilt Detection Switches Containing a Photo Sensor
AHF2 (TiP) Switches
For detection: Fall Detection Switches

For Ta = 25°C and applicable circuit conditions
1) Operation characteristics (Operation speed 6 degrees/
second)
• Operation angle (Output: V
OL
→ V
OH
): 25 to 60 degrees
• Return angle (Output: V
OH
→ V
OL
): Min. 20 degrees
2) Output (V
O
) characteristics (The sphere must be stationary.)
• V
OL
(photo transistor ON): Max. 1.0 V (horizontal)
• V
OH
(photo transistor OFF): Min. 4.0 V (inclined at an angle
of at least 60 degrees)
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.
Refer to the “Preventing a malfunction” of “CAUTIONS FOR USE”.
