E3JK-R4M1 AC/DC Retroreflective Photoelectric Sensor

E3JK-R4M1 AC/DC Retroreflective Photoelectric Sensor Introduction:

• Similar to the Omron E3JK-R4M1, our E3JK-R4M1 is a reflective photoelectric sensor that uses 660 nm visible light to detect the presence of an object.

• The photoelectric sensor has many advantages over capacitive proximity sensors, both of two kinds of proximity sensors can be used to detect any objects, no matter if the material is metal or non metal. But photoelectric sensor detection distance is much further.
• Its detection distance can reach 4 meters. Once an object is within this range and blocks the light between the emitter and receiver, there will be a digital output, either high level voltage(NO contact) or low level voltage(NC contact).
• Its working voltage can be 24-240VAC/DC, output is dry contact SPDT relay output, capacity is 3 amps@250VAC(resistive load), and it can be used to control AC or DC loads from external power sources. 
• The load capacity of the E3JK-R4M1 relay output is much higher than that of transistor PNP or NPN outputs, which can usually only drive loads of 100-200mA. More differences between the transistor and relay outputs, please read our this article: Transistor Vs Relay Output In Proximity Sensor: What Are The Differences?
  
• Applications of this photoelectric sensor include liquid level detection, counting the number of objects on a conveyor belt, and position detection of moving objects, and so on.
