Infrared Photoelectric Switch Category_Display & LED/Accessories The board has an integratedThis is a pair of photoelectric switches with a detection distance of up to 1. 5m and a fast and stable response time of less than 1ms. The module consists of a transmitter and a receiver. The transmitter contains an infrared diode that can emit infrared rays with strong penetration, thereby ensuring that the sensor can achieve stable signal reception regardless of weather, which greatly improves its measurement accuracy. The module has a small size
