Applications

Rotary Encoder is a representative detector to convert mechanical rotational displacement (analog quantity) to electrical pulse (digital quantity). Rotary encoders can be used for many kinds of applications in various fields such as position, angle or velocity measurement of mechanical instrument, control of rotational quantity or rotational speed in motor.
Ono Sokki provides a variety of rotary encoders ranging from general purpose industrial type to heat resistant type for specialized usage, space-saving compact type for your specific application. Roller encoder, which is applied equipment of rotary encoder, is also available for measurement of moving distance or speed.

2-ch calculation
Features
Reversible counter for measurement of linear displacement, displacement or dimension etc.
For data communication to an external equipment, comparator, BCD, analog and RS-232C are available. 4 kinds of comparators can be set up.
Features
DC power input (12 to 42 VDC) is convenient for in-vehicle use.
Display of frequency/rotational speed can be selected.
Input frequency range: 1 to 120kHz
Features
The PA-330Z receives the square wave signals from the rotary encoder, and converts it to low impedance signals suitable for long distance transmission after waveshapening and amplifying via photocouplers which provide isolation between input and output.
A 12VDC external power supply is provided for use with the DC powered RP series encoder.
The case is sealed construction which allows closely mounting to the encoder.
