Roberee Reflection Light Barrier, E3JK-R4M1 Reflection Photoelectric Sensor AC 90-250V 3A Photoelectric Switch for Automatic Garage Door Alarm Sensor DIY Sensor Stair Light
The Story
Roberee Reflection Light Barrier, E3JK-R4M1 Reflection Photoelectric Sensor AC 90-250V 3A Photoelectric Switch for Automatic Garage Door Alarm Sensor DIY Sensor Stair Light
Technical data: Structure Separate Amplifier Type Method for detecting the type of reflection Voltage: AC 90-250V Output current: 3A. Ambient temperature: -30 °C to + 65 °C. Size: 5 x 5 x 2 cm. Advantages: Small, multifunctional, long service life, high precision, fast response, Detection distance and advantages against light, electricity and magnetic interference ability. Package includes: 1 x photoelectric sensor (including screws)
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.
