SKU: AF-189

Limit Drive experimental kit

1)AF-189 is a training system designed in a planar (large milling machine) type to help understanding  of the operating principle and automatic control of limit switches from basic operation to applications.         
2) Limit switches are largely categorized into large type, medium type, small type and micro type.         
3) Limit switches can also be classified based on size and shape of dog and cam and actuator type.         
4) Strictly speaking, it is reasonable to classify limit switches based on actuator type.         
5) Actuator types include fixed roller lever type, adjustable roller lever type, adjustable lot lever type,roller lever lamp type, twin lever lock type, fixed large roller lever type, coil spring type, push roller type, etc.         
6) The sensing switch is intended to detect the status or change in a control target and is used to detect various control quantities such as location, liquid level, pressure, temperature, voltage, etc.         
7) Limit switch is widely used to detect contact of an object with the contactor. When an object contacts the contactor of a limit switch, the contactor moves to close or open the internal contact Limit switch is a kind of sensor for detecting location and is widely used for bulky work pieces or work pieces processed at a low speed and for applications with issues of cost efficiency and noise rather than applications         
    requiring precise control.         
8) The inclined contact is called CAM and the sharp piece is called DOG under the operating condition of a limit switch. CAMs are categorized into the linear type that detects plus or minus offset from the specified position and the rotary type that detects number of revolutions. DOG is installed to determine arrival at a specified position for pallets traveling horizontally or vertically.         
9) Compatible with PLC and sequence trainer.         
10) Applies the limit switches used in the industry         
11) Practice driving and control of limit switches
