MODEL: M8PP1-[1][2][3][4]-R[5]

ORDERING INFORMATION

• Code number: M8PP1-[1][2][3][4]-R[5]

Specify a code from below for each of [1] through [5].

(e.g. M8PP1-B7A1A12-R/Q)

• Input frequency (e.g. 0 – 1000 Hz)

• Output pulse width (e.g. 75 msec.)

Use Ordering In-formation Sheet (No. ESU-5484) for Input

Codes B:DC voltage pulse or E: AC voltage pulse, or for non-

standard output pulse width.

• Specify the specification for option code /Q

(e.g. /C01 )

[1] INPUT

Caution: With a current exceeding 30 mA, the pulse isolator

stops feeding the sensor excitation, until the sensor is

removed and connected again.
