These electronic devices are designed to detect and measure physical or environmental parameters and convert them into electrical signals. They play a vital role in industrial applications by providing real-time data for monitoring, control, and automation purposes. There are different types of sensors, including temperature sensors, pressure sensors, proximity sensors, and optical sensors, each designed to sense specific parameters. The selection of the right sensor depends on factors such as application requirements, accuracy, range, response time, and environmental conditions. SIGMA Surplus carries Banner sensors, Keyence sensors, Sick sensors, as well as many others from top OEMs.
