Limit Switch

Kit includes a pair of simple limit switch sensors custom built for the VEX Robotics Design System.

Switches send a signal to the Microcontroller when that are triggered.

These switches are great for signaling when a robot arm has reached the top or bottom of it's motion.

Descripción detallada del articulo

Limit Switch Sensor Signal :

The limit switch sensor is a physical switch.

It can tell the robot whether the sensor’s metal arm is being pushed down or not.

Switch Type :

SPDT microswitch, configured for SPST Normally Open behavior.

Behavior:

When the limit switch is not being pushed in, the sensor maintains a digital HIGH signal on its sensor port.

This High signal is coming from the Microcontroller.

When an external force (like a collision or being pressed up against a wall) pushes the switch in, it changes its signal to a digital LOW until the limit switch is released.

An unpressed switch is indistinguishable from an open port.

Compatibility :

• All VEX Microcontrollers.
• 3-Wire Extension Cables.

Caracteristics :

• Provide feedback to Microcontroller as events "happen"
• Bendable sheet metal switch "arm" is very versatile
• Useful as a trigger in a variety of applications
• Functionality is pre-programmed in the VEX Microcontroller

Kit Contents :

• (2) Limit Switch Sensors
• (4) 8-32 3/8" Screws
