OMRON introduce Optical Sensors with Longer Range and Enhanced Performance, samples available from Anglia

OMRON has release a new series of optical sensors, featuring a longer detection distance. The OMRON B5W sensors are particularly effective at identifying black, transparent, reflective and other hard to detect surfaces, the new range also features enhanced performance in this area.

OMRON B5W Light Convergent Reflective (LCR) Sensors detect target objects much more reliably than general reflection photo sensors, even those that are often a challenge such as reflective, transparent, diffuse or black surfaces. The sensor’s convergent light beam can be accurately set to trigger on the presence of an object within a tightly specified target area, and ignore any objects in the background or foreground.

The OMRON B5W-LB LCR sensors offer enhanced performance compared to the existing B5W-LA devices, and are offered in super miniature and miniature form. The miniature B5W-LB2101 and LB2112 are available with analogue or digital outputs with a sensing range of 10-55mm for white paper, falling to 10-40mm for black. The device is sized at 40 x 8.4 x 15.9 mm. For applications requiring an even more compact solution, the super-miniature B5W-LB1112 is just 26 x 8.4 x 13mm. It offers a sensing distance of 2-10mm for white paper and 3-8mm for black. All digital devices are offered in light-on and light-off form and are sealed to IP50.

The OMRON B5W-LB Light Convergent Reflective (LCR) sensors are distinguished by the reliability and repeatability of their detection performance, even when presented with target items of different colours and types of surface including reflective surfaces. Applications include detecting transparent cups and glasses in vending machines, diffused surfaces that scatter incident light such as carpets, black surfaces that absorb light, mirrored surfaces and other objects that are often a challenge for traditional sensors.
The devices are also good for general use to detect target items of various different colours. For example, the B5W can be used in a robot cleaner to detect a step. The B5W can reliably distinguish wood, glass, carpet and other floor surfaces from a downward step, to avoid risk of the robot falling. Other functions that can be reliably fulfilled by the B5W-LB include detection of coffee bean levels in drinks machines (low reflectivity) and the detection of paper of all colours including transparent sheets in printers.

The industry leading performance of the OMRON B5W-LB sensors allows them to be used in a wide range of application including Energy Meters, Building Automation, Lighting, Security, Lifts and Elevators, White Goods, Domestic Appliances and Boiler Controls.
