Omron E3X-A51

The Omron E3X-A51 is a high-performance fiber-optic photoelectric sensor designed to offer precise and reliable detection in a variety of industrial applications. This sensor is part of the E3X series, which is known for its fast response times, extended sensing distances, and self-diagnostic functions.

Equipped with a PNP open collector output, the E3X-A51 operates within a supply voltage range of 10 to 30 VDC, ensuring compatibility with a broad range of industrial equipment. The sensor features a pulse-modulated green LED light source with a wavelength of 565 nm, which is particularly effective for mark sensing and colour differentiation tasks.

The E3X-A51 offers versatile operation modes, including Light-ON and Dark-ON, which can be easily selected via a switch. Sensitivity adjustments are straightforward, thanks to an 8-turn potentiometer with a clutch and indicator, allowing for fine-tuning to meet the demands of specific applications.

This sensor does not provide mutual interference protection, which means careful consideration should be given to the placement and application environment to prevent cross-talk between sensors. The maximum load capacity is 100 mA at 40 VDC max, with a maximum ON-state voltage drop of 1 VDC at 100 mA, ensuring efficient power usage.

The response time of the E3X-A51 is impressively quick, with a maximum of 200 µs, making it suitable for high-speed detection tasks. Additionally, it features an OFF-delay timing function, adjustable from 0.01 to 0.1 seconds, providing flexibility in timing critical operations.

For circuit protection, the E3X-A51 includes output short-circuit protection and DC power reverse polarity protection, enhancing the durability and longevity of the sensor. The status of the sensor is easily monitored through the light received (red LED) and output stability (green LED) indicators.

The sensor's case is made from heat-resistant ABS, and the cover is constructed from polycarbonate, offering robust protection in challenging industrial environments. It can be mounted on a DIN rail track or directly onto a flat surface through holes in the provided bracket, facilitating easy installation.

The E3X-A51 comes with a prewired 5-conductor cable that is 2 m (6.5 ft) in length, contributing to a straightforward setup process. It has an enclosure rating of IEC IP66, indicating a high level of protection against dust and water, which is essential for maintaining performance in harsh conditions.

With an operating temperature range of -25° to 55°C and a storage temperature range of -40° to 70°C, the E3X-A51 is capable of functioning effectively across a wide range of temperatures, ensuring reliability in diverse working conditions.

Overall, the Omron E3X-A51 fiber-optic photoelectric sensor is a versatile and reliable choice for industrial sensing applications where precision, speed, and adaptability are paramount.
