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
having a total cross-section area of 0.3 mm
2
. The total cable length
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.
