In recent times, there has been more emphasis on high standards of cleanliness and hygiene, including frequent hand washing and sanitizing. This is especially important in scenarios that necessitate frequent contact. Hand sanitizers are part of the Antiseptic Hand Washes or Healthcare Personnel Hand Washes category and are designed for frequent use to reduce the number of transient micro-organisms on the skin. To reduce the need for contact with hand sanitizer dispensers, contactless hand sanitizer dispensers have been developed.
The contactless hand sanitizer dispenser solution developed by Avnet automatically dispenses a controlled amount of sanitizer when it detects the proximity of the user’s hand. This solution helps to conserve the amount of sanitizer used and stems the transmission of infectious diseases while maintaining a high level of hygiene on the sanitizer dispenser. This low-cost solution is perfect for deployment in a wide range of locations, with the lowest cost E-BoM.
