CdS Photoconductive Cells(Light Dependent Resistor)

Description

Sen Tech, a trusted light dependent resistor supplier, offers high-performance CdS photoconductive cells engineered for precise and efficient light detection across a wide range of applications.

Our photoconductive cells are sensitive semiconductor components that operate on the photoconductive effect, where exposure to light reduces electrical resistance, increasing current flow. When voltage is applied across the CdS (Cadmium Sulfide) cell, changes in light intensity are accurately converted into electrical signal variations.

Thanks to their compact design and strong current output per sensing area, Sen Tech’s CdS photoconductive cells can directly drive relays, making them ideal for light-sensitive automation and control systems. Manufactured under strict quality control standards, our products deliver the performance, consistency, and reliability you can count on.

Whether you need standard solutions or custom configurations, Sen Tech is your dependable partner in advanced light detection technology.

Features

  1. Epoxy encapsulated for enhanced protection and stability
  2. Offered in four CdS types to meet different performance requirements
  3. High output current density despite small size
  4. Excellent for integration into light-sensing and automatic control circuits
