The explanation about the built-in protection function is as follows.
Reverse connection protection・・・ This function protects the circuit by preventing current from flowing to the internal circuit when +24V and 0V are connected
in reverse on the power supply line of the base.
Overheat protection ・・・This function measures the temperature inside the Base part and stops the power supply when a certain temperature isexceeded. It will restart when the temperature drops.
Short-circuit protection ・・・This function protects the circuit by turning off the output for a certain period of time when a current exceeding the specifications
flows through the signal output line due to unloaded wiring.
Overcurrent protection ・・・A function that protects the circuit by detecting the current inside the Base part and stopping transmission for a certain period oftime when a certain current value is exceeded.
Output surge absorption protection・・・ A surge absorption circuit is built in to protect the output circuit.
Metal facing protection of the head・・・ When metal is detected, transmission is stopped for a certain period of time to protect the circuit.

Installation method
・To avoid the influence of surrounding metals and mutual interference between products, be sure to open a space larger than the value
shown in the table below. In addition to the mounting surface, only one surface of A (periphery) can beThe screw tightening torque is 1.5N･m.

ASide view

A・Use a constant voltage power supply such as a switching power supply.
(If a power supply with ripples above the rating, such as a full-wave rectified power supply, is used, it may cause malfunction.)(^_^)

・If the power supply exceeds the rated voltage, there is a risk of overheating and ignition.
Before supplying power, be sure to check that the power supply is specified in the specifications.

・When wiring the cable by bending it, use the cable outlet.
Install so that the cable is straight (approximate: about 10 mm)
Install the cable with a bending radius of 50 mm or more. (Figure 2)

・Design it so that it can be used under the wiring and surrounding environment conditions specified in the specifications. Also, design to satisfy
the "transmission distance", "center offset", "Output voltage", and "Output current". Designs outside the specifications may cause unexpectedmalfunctions, troubles, and malfunctions due to deterioration of internal parts.

50mm

・Excessive force on the cable during installation to avoid excessive stress
Please do not pull with.
・Fix the cable so that the sensor, the base of the sensor, and thecable itself are not shaken or shocked.

・When wiring for installation, maintenance, failure, etc., be sure to check that the main breaker (power panel) is cut before performing thework. If you work while the line is live, you may get an electric shock or malfunction.
・As with other electronic devices, inrush current may be generated when the system starts up, so please set the power supply in considerationof the inrush current.

(Fig. 2) Cable bending radius・Since metal overheating and internal elements may be damaged,
install the Base part so that it does not face metal, and thenturn on the power. (Fig. 3)

・Design the system so that the entire system works safely even if the external power supply is abnormal or the product fails.

metalmoisture・ If foreign matter get inside the device from the end of the cable,
it may cause fire, smoke, fire, electric shock, or malfunction
due to malfunction or short circuit. (Fig. 4)

・A remote sensor system is a system that supplies and transmits power and signals in a non-contact manner. Please do not use it for any purpose
other than this purpose.
・Design with the combination described in the instruction manual or user's guide. Opposition in any other combination may cause malfunction or damage.
