Precautions 

## Safety Precautions 

## **Power Supply** 

Do not impose an excessive voltage on the E2A, otherwise it may be damaged. Do not impose AC current (100 to 240 VAC) on any DC model, otherwise it may be damaged. 

## **Load Short-circuit** 

Do not short-circuit the load, or the E2A may be damaged. 

The E2A’s short-circuit protection function will be valid if the polarity of the supply voltage imposed is correct and within the rated voltage range. 

## Correct Use 

## **Designing** 

## Power Reset Time 

The Proximity Sensor is ready to operate within 100 ms (160ms for NO+NC -B3 / -C3 types) after power is supplied. If power supplies are connected to the Proximity Sensor and load respectively, be sure to supply power to the Proximity Sensor before supplying power to the load. 

## Effects of Surrounding Metal 

When mounting the E2A within a metal panel, ensure that the clearances given in the following table are maintained.

|If true flash mounting is necessary, apply a free zone of||
|1.5 mm.||



## **Wiring** 

Be sure to wire the E2A and load correctly, otherwise it may be damaged. 

## **Connection with No Load** 

Be sure to insert loads when wiring. Make sure to connect a proper load to the E2A in operation, otherwise it may damage internal elements. 

## **Do not expose the product to flammable or explosive gases.** 

## **Do not disassemble, repair, or modify the product.** 

## Power OFF 

The Proximity Sensor may output a pulse signal when it is turned OFF. Therefore, it is recommended that the load be turned OFF before turning OFF the Proximity Sensor. 

## Power Supply Transformer 

When using a DC power supply, make sure that the DC power supply has an insulated transformer. Do not use a DC power supply with an auto-transformer. 

## Mutual Interference 

When installing two or more Sensors face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained. 

(Unit: mm) 

||||||(Unit: mm)|(Unit: mm)|
|---|---|---|---|---|---|---|
|**Type**|**Dimension**|**M8**|**M12**|**M18**|**M30**||
||||||**Short**<br>**barrel**|**Long**<br>**barrel**|
|Shielded|A|20|30|60|110||
||B|15|20|35|70||
|Non-shiel-<br>ded|A|80|120|200|300|300|
||B|60|100|120|200|300|



**2.** In the case of using the supplied nuts. If true flush mounting is necessary, apply a free zone of 4 mm.

## **Wiring** 

## High-tension Lines 

## Wiring through Metal Conduit **:** 

If there is a power or high-tension line near the cable of the Proximity Sensor, wire the cable through an independent metal conduit to prevent against Proximity Sensor damage or malfunctioning. 

## Cable Extension 

Standard cable length is less than 200 m. 

The tractive force is 50 N. 

## **Mounting** 

The Proximity Sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistivity. 

Do not tighten the nut with excessive force. A washer must be used with the nut. 

## **Maintenance and Inspection** 

Periodically perform the following checks to ensure stable operation of the Proximity Sensor over a long period of time. 

**1.** Check for mounting position, dislocation, looseness, or distortion of the Proximity Sensor and sensing objects. 

**2.** Check for loose wiring and connections, improper contacts, and line breakage. 

**3.** Check for attachment or accumulation of metal powder or dust. 

**4.** Check for abnormal temperature conditions and other environmental conditions. 

**5.** Check for proper lighting of indicators (for models with a set indicator.) 

Never disassemble or repair the Sensor. 

## **Environment** 

## Water Resistivity 

The Proximity Sensors are tested intensively on water resistance, but in order to ensure maximum performance and life expectancy avoid immersion in water and provide protection from rain or snow. 

## Operating Environment 

Ensure storage and operation of the Proximity Sensor within the given specifications. 

|**Type**|**Type**|**Torque**|
|---|---|---|
|M8|Stainless steel type|9 Nm|
||Brass type|4 Nm|
|M12||30 Nm|
|M18||70 Nm|
|M30||180 Nm|



## Inrush Current 

A load that has a large inrush current (e.g., a lamp or motor) will damage the Proximity Sensor, in which case connect the load to the Proximity Sensor through a relay.
