Omron E3JK: Built-in Power Supply Photoelectric Sensor
The Omron E3JK photoelectric sensor series includes three primary sensing methods: through-beam, retro-reflective, and diffuse-reflective, each designed for specific applications and distances.
Through-beam photoelectric sensors (E3JK-TR11/12/13/14 and E3JK-TN11/12/13/14) offer the longest sensing distances, up to 40 meters, suitable for detecting objects with high precision. They feature both AC and DC power supply options and provide relay or transistor output, which cater to diverse industrial requirements.
The retro-reflective E3JK photoelectric sensors (E3JK-RR11/12/13 and E3JK-RN11/12/13), with or without MSR (Mirror Surface Rejection) function, have a range of up to 11 meters.
These are ideal for situations where a reflector can be used, simplifying installation by negating the need for a receiver on the opposite side. Diffuse-reflective models, such as the Omron E3JK-DR11/12/13/14, operate within a 2.5-meter range.

People Also Ask
What is the operating range of the Omron E3JK photoelectric sensors?
Omron E3JK photoelectric sensors offer an operating range varying by type: through-beam sensors reach up to 20 meters, retro-reflective models up to 4 meters, and diffuse-reflective types up to 1 meter.
Omron e3jk photoelectric sensor working principle
Omron E3JK photo sensor operates on a principle where a light beam, emitted by the sensor, is reflected back or interrupted by the target object, triggering a response to detect its presence or absence within its range.
What is the response time of the Omron E3JK sensor?
The Omron E3JK sensor has a rapid response time, typically within the range of 10 to 20 milliseconds, allowing for quick detection and signaling in various automation and safety applications.
Which sensor type requires separate emitter and receiver?
The through-beam type of the E3JK photoelectric sensor requires separate emitter and receiver units, ensuring reliable detection for long distances, ideal for high-precision applications where the object breaks the beam between the two units.
