Failure to follow this instruction may result in fire or product damage.
Cautions during Use
- Follow instructions in ‘Cautions during Use’.
Otherwise, it may cause unexpected accidents. - 2 – 24 VDCᜡ power supply should be insulated and limited voltage/current or Class 2, SELV power supply device.
- Use the product, after 0.8 sec of supplying power.
- Wire as short as possible and keep away from high voltage lines or power lines, to prevent surge and inductive noise.
Do not use near the equipment which generates strong magnetic force or high frequency noise (transceiver, etc.).
In case installing the product near the equipment which generates strong surge (motor, welding machine, etc.), use diode or varistor to remove surge. - This unit may be used in the following environments.
– Indoors (UL Type 1 Enclosure)
– Altitude max. 2,000 m
– Pollution degree 3
– Installation category II
Cautions for Installation
- Install the unit correctly with the usage environment, location, and the designated specifications.
- Do NOT impacts with a hard object or excessive bending of the wire lead-out. It may cause damage the water resistance.
- Do NOT pull the Ø 3.5 mm cable with a tensile strength of 25 N, the Ø 4 mm cable with a tensile strength of 30 N or over and the Ø 5 mm cable with a tensile strength of 50 N or over. It may result in fire due to the broken wire.
- When extending wire, use AWG 22 cable or over within 200 m.
In case of IO-Link mode, the cable length between the unit and the IO-Link Master should be under 20 m.

Setting Distance Formula
Detecting distance can be changed by the shape, size or material of the target.
For stable sensing, install the unit within the 70 % of sensing distance.
Setting distance (Sa)
= Sensing distance (Sn) × 70 %Mutual-interference & Influence by Surrounding Metals
■ Mutual-interference
When plural proximity sensors are mounted in a close row, malfunction of sensor may be caused due to mutual interference.
Therefore, be sure to provide a minimum distance between the two sensors, as below table.
■ Influence by surrounding metals
When sensors are mounted on metallic panel, it must be prevented sensors from being affected by any metallic object except target. Therefore, be sure to provide a minimum
distance as below chart.
