Introduction to AHF11

AHF11 is a range of motion sensors specially designed for tilt switch applications. It is an essential component in systems such as home and industrial automation, building monitoring and security, and many other high-tech applications.

Basic Properties of AHF11

The AHF11 range of motion sensors are designed to provide reliable and accurate readings when it is deployed in a variety of environments. It is constructed from materials with superior durability that can withstand tough conditions. It also has a very wide angle range of about 25 degrees for measuring tilt or angular motion, and is equipped with operating temperature range of -20 to +85 degree Celsius. Its contact output type provides low voltage (3-32 VDC) and low current (5mA max) signals.

The Application Fields of AHF11

The AHF11 is a highly versatile motion sensor and can be implemented in many application fields as it has low power consumption and high reliability. Typical applications are home and industrial automation, like appliance control, medical equipment control, car security systems, and in alarm and security systems. In the fields of building and automotive monitoring, the AHF11 can be used to detect when furniture is moved, when doors and windows are opened, and when vehicles make a sudden stop. It can also be used in security systems to detect the presence or absence of an object, as well as to detect physical intrusion or vibration.

The Working Principle of AHF11

The AHF11 uses a capacitive technology for its motion sensing. This technology enables the sensor to detect the changes in its capacitance when its environment is disturbed. The motion is detected when the static capacitance between two electrodes changes due to the mechanical movement of an outer object. Then an electronic signal is sent to the outside device to indicate the occurence of motion. The signal is digitalized through the conversion of AC to DC and vice versa.The capacitance between the electric plates of the AHF11 is determined by the distance between them. At the motionless state, the capacitance remains constant. As the motion is detected, the capacitance changes, and the switch is triggered to open or close. The structures of the AHF11 are designed to maximize its sensitivity, so that even the slightest motion can be detected and the switch turns on or off accordingly.

Conclusion

The AHF11 is an ideal motion sensor for tilt switch applications. Its high sensitivity, wide angle range, low power consumption and operating temperature range render it suitable for a variety of fields, including home and industrial automation, building monitoring and security. The AHF11 works based on the capacitive motion sensing technology. Using this technology, the sensor can detect changes in its capacitance when an object disturbs the environment and send a signal to the external device indicating the occurrence of motion.
