Safety Precautions

Refer to Warranty and Limitations of Liability.

This product is not designed or rated for ensuring

safety of persons either directly or indirectly.

Do not use it for such purposes.

Make sure that this product is used within the rated ambient

environment conditions.

● Wiring

• Connection is made using a connector. Do not solder to the pins

(leads). The pins (leads) are soldered to the internal board of the

Sensor. Therefore, direct soldering of the pins (leads) may result in

an internal disconnection causing malfunction.

• When extending the cable, use an extension cable with conductors

must be 2 m maximum.

• To use a cable length longer than 2 m, attach a capacitor with a

capacitance of approximately 10

μF to the wires as shown below.

The distance between the terminal and the capacitor must be within

2 m. (Use a capacitor with a dielectric strength that is at least twice

the Sensor's power supply voltage.)

• Make sure the total length of the power cable connected to the

product is less than 10 m even if a capacitor is inserted.
