Photoelectric Sensors Diffuse Reflective

What are Photoelectric Sensors?

We are a Photoelectric Sensors Diffuse Reflective Suppliers, Distributors & Importers in Mumbai, India. Carlo Gavazzi Photoelectric Sensors are devices that detect changes in surface conditions, objects, or colors and categorize them using light. They also operate by transmitting a light beam and measuring the reflection of cuts as well as how much this has been blocked when another object stands in its way. Because these sensors can detect an object without even touching it, they are one of a very commonly used category which is further widely applied in automation and manufacturing. Perfect for high-speed and precision counting, positioning to locate parts, or detecting part presence.

Photoelectric Sensors Diffuse Reflective

Product Overview:

The PA18CSD. family provides low-cost, general-purpose Diffuse-reflective sensors in 18 mm diameter industrial cylindrical PBTP housing. They find applications in simple tasks where a basic sensor gives adequate sensing performance. The sensors are easy to use and require no adjustment except the 400 mm diffuse adjustable type. The output is a 4-wire complementary (NO and NC) output in NPN (current sinking) or PNP (current souring).
