Product Features

• Operating principle: the reflective light barrier uses the light beam blocked or reflected by the detected object to detect the presence of the object via the synchronous loop of the gate circuit.
• High-quality material: the housing of the photoelectric switch is made of fireproof ABS material, is small and durable. It adopts the light source type emission tube and has a stable performance.
• Multiple advantages: the light barrier sensor offers the advantages of high precision, fast response speed, long detection distance and strong resistance to light, electricity and magnetic interference.
• Intelligent function: the photoelectric sensor switch uses integrated circuit technology and SMT surface mounting technology and has intelligent functions such as delay, extension, external synchronisation and anti-interference.
• Easy to use: photoelectric switches can be used in security systems and in the manufacturing industry, often for garage doors or automatic doors. Alarm sensors, DIY sensor stair lights, etc.
