WFM30-40N311

Optical sensors, also known as phototransducers, are devices designed for detecting light and responding accordingly. One of the most common types of optical sensors includes photointerrupters, and they consist of a pair of sensors divided by a section of opaque material, or a gap, which is called the slot. When a light beam passes through the slot, the two sensors are given different inputs. Photointerrupters used for general purpose applications are typically slot type, with a transistor output, such as the WFM30-40N311 model.

Application Field

The WFM30-40N311, which is a slot type photointerrupter module, is small and compact and is designed for general purpose use. It is often used in different types of automated machinery and is suitable for applications involving movement control, switching operation control, and signal transmission. It is also used in consumer products, such as remote control toys, robotic vacuums, and automatic door openers. Additionally, it is used for industrial purposes, such as in automated manufacturing, in automation and control systems, medical devices, and instrumentation.

Working Principle

The WFM30-40N311 photointerrupter module operates with a basic on/off operating principle and consists of an infrared source and receiver, a gap in between the two, and a transistor output. The IR diode on the photointerrupter module is used to emit an infrared light beam, and when something, such as a body part or an object, passes through the gap, the receiver receives a different input and triggers the transistor output. When the gap is clear, the transistor is open, and when the gap is blocked, it is closed. This enables the user to detect changes in the voltage when something passes through the gap and use this information to control electrical signals.

Overall, the WFM30-40N311 model of photointerrupter module is a small, compact, general purpose device that is used in various applications, from consumer products to industrial automation, and works on a basic on/off operating principle. Its small size and reasonable price point make it a popular choice for a wide range of applications.
