What is photoelectric sensor

Photoelectric sensors are mainly divided into 3 categories: through-beam/opposed photo sensors, retro-reflective photo sensors/Mirror-reflective Sensors and diffused optical sensors.As one of the outstanding photoelectric sensor manufacturers in China, G-TEK sensors has developed comprehensively in the field of photoelectric switches. However, the data shows that the most popular with door manufacturers is still the retro-reflective photoelectric sensor. PF50R has also become one of our best-selling products.

 


Less cost comparing with opposed typeAdvantages and Features of the Reflector Sensor

  1. Operating distances larger than diffused type
  2. High operational dependability
  3. Less mounting effort

The greatest advantage of it is the ease of installation, which is why reflective sensors are always the first choice for manufacturers or users of industrial automatic doors. Mirror-reflective sensors from G-TEK sensors are available with two different light sources: infrared LED and laser. The user can make the appropriate choice to suit their characteristics. For example, the infrared LED type is highly resistant to light, while the laser reflective sensor is more sensitive and has a larger sensing range.

PF50R Retro-reflective sensors

  1. Infrared LED Retro-reflective Photoelectric Sensor

Red LED indicates working status, easy for installation. Aspheric optical lens can eliminate stray light, and special optical structure has strong light resistance.

  1. Laser Reflection Sensor

Laser light has four unique characteristics that differentiate it from ordinary light: these are coherence, directionality, monochromatic and high intensity. It enables contactless measurement over long distances. Laser sensors are commonly used for measuring physical quantities such as length, distance, vibration, speed and orientation. Compared to conventional infrared photoelectric sensors, it has a longer detection distance and is more sensitive.
