Information related to the Low Voltage Directive
Type Free-power type
Mode No. PD5-1MA PD5-2MA
Open/close element function AC-12/DC-12
Rated impulse withstand voltage 2.5kV
Output minimum working current 5VDC 1mA or more
Turn-on time/off time 20ms/20ms
Note:Turn-on time and turn-off time are measured values of the delay time between the reference sensor output and the measurement sensor output when the disk is rotated.
Maximum response frequency 25Hz
Note:Maximum response frequency is calculated below.
Maximum response frequency = 1/(turn-on time+turn-off time)
Degree of contamination 3(Factory environment)
Electric shock protection class Out of classification
Margin gain 12%
Note: The margin gain is the value when the distance setting volume is set at the maximum distance setting range. The value for white matte paper (200x200mm).
Note Note 1: Measurement condition not specified: Ambient temperature of use= +23℃
Note 2: Be sure to install short-circuit protection (fuse, breaker, etc.) at the power input and output.
Also, use a fuse (quick break type) or breaker with a breaking current of 5A or less.

Figure: Turn-on time / Turn-off time Measurement

Figure: Turn-on time / Turn-off time  Measurement
Turn-on time and turn-off time are measured values of the delay time between the reference sensor output and the measurement sensor output when the disk is rotated.
