Precautions
This product is not designed or rated for ensuring 
safety of persons. Do not use it for such purpose.
Never use this product with an AC power supply.
Otherwise, explosion may result.
Safety Precautions
Load Short-circuit
Do not short-circuit the load, or the E2B may be damaged.
The E2B’s short-circuit protection function will be valid if the polarity 
of the supply voltage imposed is correct and within the rated voltage 
range.
Wiring
Be sure to wire the E2B 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 E2B 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.
When provided with the UL Listing Mark, the E2B series with M1 or 
MC suffix shall be used with a Listed cable/connector assembly rated 
minimum 30V, minimum 200mA, in the final installation.
Correct Use
Designing
Power Reset Time
The Proximity Sensor is ready to operate within 100 ms 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 proximity sensor within a metal panel, ensure that the 
clearances given in the Table1 are maintained. Failure to maintain these 
distance may cause deterioration in the performance of the sensor.
