An electronic dispenser (10, 100) for dispensing sheet products includes an infrared proximity sensor (18, 20) operative to detect a presence of a user's hand at a predetermined location near the dispenser (10, 100), and a feed mechanism (24) configured to engage a sheet product roll (28, 30) to cause a quantity of sheet product to be dispensed therethrough. The infrared proximity sensor (18, 20) is configured to have an adjustable sensitivity to vary a detection range of the infrared proximity sensor (18, 20). The feed mechanism (24) has a motor operative in response to the infrared proximity sensor (18, 20) to engage the feed mechanism (24). |
