Hand induction switch, a/induction door opener, the electric induction switch. Palm induction switch overall characteristics: using infrared modulation demodulation, will not produce interference and disturbance signal. Objects by hand (or reflection) positive non-contact induction, clean health. Induction 1 ∽ 15 cm distance is adjustable, can be set according to different occasions. With low power design, equipment service life is longer. Imported high sensitivity infrared tube, convenient induction in a timely manner. Positive dark hole fixed, installation simple wiring, the outward appearance is full of sense of science and technology. A relay dry contact output, convenient and connections of various kinds of door control equipment. There are instructions induction lights. AC/DC 12 ∽ 36 v power input. Main technical parameters: power supply: AC/DC 12 v ∽ 36 v static power: 62 ma current action: 115 ma induction distance: 1 ∽ 15 cm adjustable frequency modulation demodulation: 38 KHZ temperature environment: - 20 ℃ ~ 45 ℃ environment humidity: 10 ~ 90% RH appearance size: 113 mm (L) x 63 mm (W) x 20 mm (Hz) fixed way: hidden screw fixation
