Photo Sensor Supplier
A Photo Sensor, also known as a Photoelectric Sensor, is an electronic device that detects the presence, absence, or distance of an object using a light beam (infrared, visible, or laser). When the light emitted from the sensor is interrupted or reflected by an object, the sensor detects this change and sends an electrical output signal.
SCB Industries is a trusted Photo Sensor supplier in Kolkata, West Bengal, Odisha, Bihar, Chhattisgarh, Assam, Gujarat, Pune, and Vapi, offering high-performance sensors suitable for industrial automation, packaging, and process control. Our sensors are known for accuracy, fast response time, and long service life, making them ideal for diverse industrial applications.
