The RE46C143S16F is a passive infrared detector that is often used in sensor applications. It consists of an integrated circuit and an infrared lens. It is designed to detect motion in home or industrial applications. This makes it very suitable for use in intruder and safety systems, or as an input or switch device in automation and security control systems.

The device is an open collector output PIR motion detector IC. It is designed to operate at 9VDC to 12VDC and requires a 0.3 μF ceramic input capacitor. The lens used is a Fresnel type with a sensitivity range of 0.125° to 130°. The RE46C143S16F also has a response time of less than 0.4 seconds and a detection range of 4m.

The working principle of the RE46C143S16F is based on a thermopile infrared sensor. This is a device that detects changes in temperature using infrared radiation. The device consists of two elements, a hot junction and a cold junction. It uses the principle of the Seebeck effect, where a voltage is produced when a temperature difference exists between the two junctions. The PIR motion detector IC utilizes the infrared radiation from an object in the viewing range and converts it into an electrical signal with a varying voltage. By detecting changes in the voltage amplitude, the device can detect motion within its range.

The principle of operation allows the device to detect motion even in total darkness, since it relies on the heat generated by objects in its field of view. When an object, such as a human or animal, enters the viewing range, the infrared radiation generated by the object is detected by the device and generates an electrical signal. This signal is then used to switch a circuit or activate an alarm.

The RE46C143S16F is used in a variety of applications, most commonly in home alarm and security systems. It can be used to detect motion inside or outside a home, and can be used to trigger alarms or automatically activate a light. It is also used in industrial and factory settings, as it can detect motion in large controlled environments. It can also be used as an input or switch device in automation and security control systems.

The RE46C143S16F is a reliable sensor device, and is capable of detecting motion in a variety of applications. It is easy to install and is highly efficient, making it an ideal choice for a variety of sensing needs. Its low power consumption and long range make it a great choice for home and industrial applications.
