Rated Current

A current which can be continuously supplied to a load. The value of the current which can be supplied varies depending on the operating ambient temperature and installation method. For details, refer to the installation method and the output derating characteristics.

Rated Voltage

DC output voltage

Real Display

Also called as "linear spectrum". It is the amplitude of each frequency. The value is obtained by √（R2 + I2).

Reference distance

The distance from the light-emitting surface of the sensor head to the center of the measurement range. At the reference distance, the analog output voltage and the display or measurement value are 0 V.

Repeatability

The detecting distance tolerance range when a standard target is subjected to repeated detection under set conditions.

Reset

Resets the count and control output to the initial stage at which the counting operation started.

Resolution

Even when detecting a stationary target, analog output voltage fluctuates slightly due to internal noise. The amount of fluctuation is called resolution; the smaller the fluctuation, the better or higher, the resolution. Example: 0.1% of F.S. The minimum readable measurement is 1/1000th of the measuring range.

Response

Delay time until the flow of liquid in the passage area is output.

Response frequency

A sensor's maximum number of ON/OFF operations per second when repeatedly detecting standard targets aligned on a wheel.

Response frequency for analog output

When measuring a revolving or oscillating target, the displacement sensor fails to respond to the actual displacement speed (or frequency), causing a decrease in analog output level. The response frequency is defined as the frequency when the analog output level is 3 dB lower (at approximately 70%) than the stable level.

Response time

The minimum period of time required for a sensor to detect the presence of a light beam and output an ON signal, or to detect the absence of a light beam and output an OFF signal.

Responsibility

Represents the delay time, that is, the time required from pressure application to signal output.

Ripple Noise Voltage

Ripples and noise components which superimpose the DC output voltage.

RMS

The effective value of AC voltage (current). Abbreviation for "Root Mean Square". 　<=> Root Mean Square value

Root Mean Square Value

Indicates the magnitude of AC voltage/current. It is the square root of a value obtained by averaging the second power of an instantaneous value for the period of one cycle. When "100 VAC" is specified, "100 V" is an Root Mean Square value and the peak value is generally ±141.42 V. = RMS (Root Mean Square)
