Robotic grippers support a diverse range of automation solutions which is why there are different types. Grippers allow the machine to grab, hold, or move an object, similarly to how a human hand works. There are different sizes and styles which can be applied for your particular application.

Two of these options include 2-jaw and 3-jaw grippers. Their differences matter in regards to what they’re being used for, but each provides its own benefits for a variety of functions. Here are the differences between a 2-jaw and 3-jaw end of your arm robotic gripper.

A 2-Jaw Gripper Offers Affordability and Ease of Automation

2 Jaw GripperOne of the most popular styles for automation processes, all styles of 2-jaw grippers provide two different locations where the “fingers” of the gripper touch the item that needs to be manipulated. The gripper closes in towards the center, allowing it to be adapted to the particular shape of an object and providing equal amounts of force for stability.

2-jaw grippers are simple enough to apply to automated processes in which consistency is key, but they’re also useful across a wide range of tasks. 2-jaw grippers offer affordable solutions for people who need simple yet dependable grippers for their machines.


3-Jaw Grippers Provide More Reliability and Accuracy

3 Jaw GripperInstead of having two locations where the end of the gripper touches the object, there are three in 3-jaw grippers. Having another “finger” to support the movement of the object allows the object to be moved more accurately, and provides better centering. Its parts move together to provide the most secure grip on an item.

What this means is that 3-jaw grippers provide more flexibility, and the gripper can even adjust itself to the specific shape of the component being grasped. In addition to its reliability and accuracy, 3-jaw grippers can carry larger objects in comparison to its structure than 2-jaw grippers.

Your Choice Depends on Your Specific Application

Whether your choose a 2-jaw or a 3-jaw gripper for the end of your robotic arm really depends on what particular application you need them for. In some situations, a 2-jaw gripper will work fine, but in others, a 3-jaw gripper would prove to be a better investment.

RAD provides both 2- and 3-jaw grippers that are operated by air pressure which allows them to securely grip and provide simultaneous movement. Our grippers deliver on the reliability and cost-efficiency you need to support your automation processes!

Robots provide many benefits for companies across a diverse range of industries. One of the best benefits of robot technology is cost savings, therefore freeing up company resources to invest in other revenue-growing opportunities.

Most robots come with collision software to help prevent accidents that can lead to expensive damage. However, this software isn’t nearly as fast as it needs to be to actually prevent a collision and minimize or eliminate damage.

With RAD’s range of advanced patented Collision Sensors, RAD’s collision sensors mechanically detect when the robot arm has encountered an obstruction, absorbing the crash energy without releasing the air pressure in the collision sensor.

Keeping the air in the collision sensor prevents tooling “sag” and eliminates the effects of compressed air being released into the environment. The collision sensor quickly signals the robot to stop (within 2-8 milliseconds)—thus preventing costly damage to equipment and tooling.

Understanding the Benefits of RAD Collision Sensors Response Time

RAD collision sensors can stop a crash within 2 to 8 milliseconds—that’s between 2 and 8 one-thousandths of a second, which is faster than human response time, which is typically only as fast as 13 milliseconds.

Upon detecting the impact, RAD’s collision sensor maximizes uptime by automatically returning to within 0.0005” (0.013mm) in x, y, and z dimensions and to within ± 0.017° rotationally of its starting position to maximize uptime and eliminate the need for human intervention.

RAD’s collision sensor models also provide additional pneumatic and compliance benefits, including:

  • Allowing pneumatic adjustment so the user can easily change the amount of resistance the unit must encounter before signaling a collision.
  • Having a compliance adjustment feature that lets the user determine the amount of deflection allowed before a signal is sent to the robot’s E-stop or controller.

Collision sensors act as insurance to protect your robot. Even embedded robot language can’t stop an accident as quickly as a RAD collision sensor, and if a collision is detected, the robot won’t reset automatically.

Invest in Cost Savings and Asset Protection

By investing in cutting-edge collision sensors for your robots, you invest in long-term cost savings.

Think about it. One collision sensor alone can protect a gripper that could cost $30,000. Every millisecond counts when protecting your investment!

Even when purchasing a new robot, embedded software can’t respond like RAD collision sensors. Standard robot language attempts to stop the robot once a collision is sensed much later, sometimes 15 to 18 milliseconds seconds, costing you precious time and money in the event of a crash. 

Investing in a collision sensor can help protect your investment and prevent the need to replace expensive tooling, all as the result of a collision that could have been prevented or at the very least mitigated.

Stop Collisions and Protect Your Robots

Are you unhappy with the software included with your robot in regards to its collision response time? To create a reliable solution, prevent damage to your robots, and enforce safety, investing in the right technologies is always a smart choice. 

When collisions can result in lost revenue, reduced production, and waste, it’s time to invest in a sensor that can protect your assets. With RAD’s state-of-the-art collision sensors, you can invest in the best protection for your robots!
