La description
PM18T opposed type photoelectric sensor is our most popular model used at turnstiles. PM18T photoelectric sensor installed at the turnstile gate entrance is used to detect whether people intrude into the turnstile gate. When swiping the card outside the yellow line, there is no object at the gate entrance, and the sensor signal is normal, the wing door will open; if the person goes inside the yellow line, the sensor signal at the gate entrance changes, even if swiping the card, the wing door will not open. The purpose of this design is to prevent the opening and closing of the wing gate when swiping the card at a short distance, which may cause potential safety hazards, and also prevent ticket evasion. The product detection distance is 20m , with Reverse polarity protection, over-current and over-voltage protection functions, Epoxy resin sealing against rugged environment.
