Wiring

Connection

Make connection after turning the power off.

Use a separate route when installing wire.

Malfunction stemming from noise may occur if wire is installed in the same route as that of power or high-voltage cable.

Be sure to ground terminal FG when using a switching regulator obtained on the market. If analog output is performed connecting to a switching regulator obtained on the market, switching noise will be superimposed and product specification can no longer be met. This can be prevented by inserting a noise filter, such as a line noise filter and a ferrite element, between the switching regulator and the sensor, or by using a seriespower supply instead of a switching regulator.

Connector

Connector Connecting / Disconnecting

When connecting the connector, insert it straight onto the pin holding the lever and connector body between fingers and lock the connector by pushing the lever claw into the square groove in the body of sensor.

When disconnecting the connector, push down the lever by thumb to disengage the lever claw from the square groove. Then pull the

connector straight out.

Analog output 1 to 5V

Analog output 4 to 20mA

Output inpedance 1k

Load inpedance 50 to 600

External input : No voltage input

Reed switch or solid state switch input 30ms or more

Select response speed

To reduce ripple by slowing the response speed when ripple of analog output is large due to the effect of pulsation.

How to select

• Connect input line(white) to GND. While connected, response speed is 1.0s. (50ms when not input)
