Connection

DC type

Connection type	Method	Description
AND (serial connection)	Correct	The Sensors connected together must satisfy the following conditions: iL + (N-1) x i ≤ Upper-limit of control output of each Sensor Vs - N x VR ≥ Load operating voltage N = No. of Sensors VR = Residual voltage of each Sensor Vs = Supply voltage i = Current consumption of the Sensor iL = Load current If the MY Relay, which operate at 24 VDC, is used as a load for example, a maximum of two Proximity Sensors can be connected to the load.
OR (parallel connection)	Correct	A minimum of three Sensors with current outputs can be connected in parallel. The number of Sensors connected in parallel varies with the Proximity Sensor model.

AC type

Connection type	Method	Description
AND (serial connection)	Incorrect Correct X1 X2 Load V1 V2 V3 X4 X5	If 100 or 200 VAC is imposed on the Proximity Sensors, VL (i.e., the voltage imposed on the load) will be obtained from the following. VL=Vs-(residual voltage x no. of Proximity Sensors) (V) Therefore, if VL is lower than the load operating voltage, the load will not operate. A maximum of three Proximity Sensors can be connected in series pro- vided that the supply voltage is 100 V minimum.
OR (parallel connec- tion)	Incorrect A B Correct A B C Load A B C Load VAC power supply V5	In principle, more than two Proximity Sensors cannot be connected in parallel. Provided that Proximity Sensor A does not operate with Proximity Sen- sor B simultaneously and there is no need to keep the load operating continuously, the Proximity Sensors can be connected in parallel. In this case, however, due to the total leakage current of the Proximity Sensors, the load may not reset properly. It is not possible to keep the load operating continuously with Proximity Sensors A and B in simultaneous operation to sense sensing objects due to the following reason. When Proximity Sensor A is ON, the voltage imposed on Proximity Sen- sor A will drop to approximately 10 V and the load current flows into Prox- imuthy Sensor A, and when one of the sensing objects is close to Proximity Sensor B, Proximity Sensor B will not operate because the voltage im- posed on Proximity Sensor B is 10 V, which is too low. When Proximity Sensor A is OFF, the voltage imposed on Proximity Sen- sor B will reach the supply voltage and Proximity Sensor B will be ON. Then, Proximity Sensor A as well as Proximity Sensor B will be OFF for approximately 10 ms, which resets the load for an instant. To prevent the instantaneous resetting of the load, use a relay as shown on the left.

Caution

Power supply

Do not impose an excessive voltage on the E2Q2, otherwise it may explode or burn.

Do not connect an AC power supply to any DC model. If AC power (100 VAC or more) is supplied to the sensor, it may explode or burn.

Do not connect the AC types without load to the power supply. The sensor will be damaged.

Be sure to abide by the following precautions for the safe operation of the Sensor.

Wiring

Power Supply Voltage and Output Load Power Supply Voltage

Make sure that the power supply to the Sensor is within the rated voltage range. If a voltage exceeding the rated voltage range is supplied to the Sensor, it may explode or burn.

Load Short-circuiting

Do not short-circuit the load, otherwise the Sensor may be damaged.

Connection without Load

Do not connect the power supply to the Sensor with no load connected, otherwise the internal elements may explode or burn.

Operating Environment

Do not use the Sensor in locations with explosive or flammable gas.

Correct Use

Design

Effects of Surrounding Metal

Provide a minimum distance between the Sensor and the surrounding metal as shown in the table below.

Effects of Surrounding Metal (Unit: mm)

Model	Length	A	B	C
E2Q2-N15□□-□□E2Q2-N20□□-□□		45	0	0
E2Q2-N30M□□-□□		90	250	30
E2Q2-N40M□□-□□		120	300	40

Mutual Interference

If more than one Sensor is located in parallel, ensure to maintain enough space between adjacent Sensors to suppress mutual interference as provided in the following diagram.

Mutual Interference (Unit: mm)

Model	Length	A
E2Q2-N15□□-□□		40
E2Q2-N20□□-□
E2Q2-N30M□□-□		120
E2Q2-N40M□□-□		150

Power Reset Time

The Sensor is ready to operate within 300 ms after the Sensor is turned ON. If the load and Sensor are connected to independent power supplies respectively, be sure to turn ON the Sensor before supplying power to the load.

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.

Sensing Object

The sensing distance of the Proximity Sensor vary with the metal coating on sensing objects.

Wiring

High-tension cables

Wiring through Metal Conduit:

If there is 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 malfunction.

Mounting

Mounting the Sensor

The Proximity Sensor must be subjected to excessive shock with a hammer when it is installed, otherwise the Proximity Sensor may be damaged or lose its water-resistivity.

Maintenance and Inspection

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

• Check for mounting position, dislocation, looseness or distortion of the Proximity Sensor and sensing objects.
• Check for loose wiring and connections, improper contacts and line breakage.
• Check for attachment or accumulation of metal powder or dust.
• Check for abnormal temperature conditions and other environmental conditions.

Never disassemble or repair the Sensor.

Environment

Water Resistivity

Do not use the Proximity Sensor underwater, outdoors or in the rain.

Operating Environment

Be sure to use the Proximity Sensor within its operating ambient temperature range and do not use the Proximity Sensor outdoors so that its reliability and life expectancy can be maintained. Although the Proximity Sensor is water resistive, a cover to protect the Proximity Sensor from water or water-soluble machining oil is recommended so that its reliability and life expectancy can be maintained.

Do not use the Proximity Sensor in an environment with chemical gas (e.g., strong alkaline or acid gasses including nitric, chromic and concentrated sulfuric acid gases).

Inrush Current

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