Longer range optical sensor for Covid-19

New Products |

Omron Electronic Components Europe has launched a longer version of its B5W optical sensor.

The B5W-DB diffuse reflector sensor has a longer sensing distance of 550mm, longer than light convergent resistance sensors of the same size making it ideal for COVID safe user interfaces. 

The optical sensor has enhanced disturbance light resistance, making the product less susceptible to ambient light such as sunlight. The sensor can be mounted from four directions and it operates with a low current consumption of 20mA maximum.

The diffuse reflector sensor opens itself up to applications in washroom equipment, sterilization equipment and entry control systems. Touchless sensors have a lower infection risk, making them Covid-secure and giving peace of mind to patrons using facilities in washrooms and other public spaces. They can also be used to activate security and door entry systems when an individual is seeking admission, and to operate sterilization equipment reducing the risk of cross-infection.

The B5W sensors are particularly effective at identifying black, transparent, reflective and other hard to detect surfaces, and the new range also features enhanced performance in this area.

In addition to the B5W-DB, the miniature B5W-LB2101 and LB2112 are still available with analogue or digital outputs with a sensing range of 10-55mm for white paper, falling to 10-40mm for black. These devices are sized at 40 x 8.4 x 15.9 mm. For applications requiring a smaller sensor, the B5W-LB1112 is 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.
