The Type C can be equipped with a range of different head and body styles, including a more durable design that is watertight and submersible. It features a straightforward wiring arrangement and relatively easy installation.

Heavy-Duty Precision Oil-Tight:Р вЂ™Р’В Also known as the Type C limit switch, this device is highly reliable due to its long electrical and mechanical lifespan.

The common types of limit switches used in industrial applications include: It is important for a limit switchР Р†Р вЂљРІвЂћСћs electrical rating to match that of the system into which it is installed in order to reduce the potential for instrument failure and ensure proper functioning.

In addition to the operational parameters and mechanical specifications of a machine, these factors include the size, mounting method, and force capacity of the switch, as well as the stroke rate involved in the operating process. Limit switch performance depends on a number of factors. Limit switch instruments are employed in a broad range of applications due to their straightforward design, relatively simple installation requirements, reliability, and resilience in withstanding environmental conditions.

A limit switch is typically composed of a series of electrical contacts coupled to an actuator that controls the mechanical device responsible for on and off functions. In order to perform these actions, limit switches are designed in a variety of shapes, sizes, and capacity ranges to accommodate differences in machine systems and production processes. When installed in a machine system, a limit switch can usually start, stop, slow down, or accelerate operations, as well as activate a forward or reverse process. Limit switches enable this and similar operations to work as semiautomatic processes by regulating an initiated action to keep it within performance parameters. The switch also deactivates the motor as the door closes, preventing it from being pushed into the ground. In the case of a garage door opener, a limit switch is responsible for turning off the motor that lifts the door before the door crashes into the lifting mechanism. A wide range of industrial machinery uses limit switches to control the movement of devices performing on a production line, but these switches are also found in non-industrial applications, such as electric motor operation and garage door opener units. As its name suggests, a limit switchР вЂ™Р’В regulates the operations of machines that are equipped with moving parts connected to a switching action mechanism.

Ultrasonic Test: test the ultrasonic sensor by telling the robot to move forward until it is 5cm away from an obstacle.

Touch Test: tests the touch sensor/limit switch to display whether or not the button/switch is pressed.

IR Obstacle Test: tests the IR obstacle avoidance sensor.

Gyro Turning Test: tells the robot to do a 90o left and right turn based on the gyro sensor.

Gyro Library Test: tests the gyro sensor to display the x,y, and z Euler angles.

Movement Test: tests the standard robot movements, such as forward, turns, and claw movement.These Arduino C codes provided show the possibilities of the robot and provide tests for different functions.
