Plug

Continuously monitor your air cylinder rod’s position and turn the cylinder on and off with a single component. These transmitters send positioning data to computers, programmable logic controllers (PLCs), and human-machine interfaces (HMIs). They're often integrated into automated systems for tasks such as timing when certain steps of your process should take place and verifying dimensions for quality control. Rated IP67, these transmitters withstand temporary submersion.

Press the buttons on the switch to toggle between voltage and current outputs. These transmitters have a plug that connects to cords with a socket (not included) so you can quickly connect and disconnect the switch.

Magnetic Air-Powered Pick-and-Place Grippers

Lift and move perforated metal sheets and other parts that standard grippers and vacuum lifters can’t hold. Compressed air pushes a magnet forward to grab parts, then retracts it to release them. A replaceable pad absorbs impact as the magnet grabs parts to protect the parts and gripper from damage.

Holding force describes how strongly the magnet can pull on your part to keep it attached to the gripper during handling. The amount of force you need depends on the part’s magnetism, thickness, flatness, and finish. For example, to lift a 2 mm thick carbon steel plate with a smooth surface, you’d need a force that’s at least three times its weight. Thin or curved parts require a higher holding force. Click on a part number and select “Product Detail” to view a chart that shows how holding force changes based on your part’s thickness.

Sensors

Add sensors to monitor the position of the magnet so your system knows whether a part has been picked up or released. They have an LED indicator that lets you know the gripper’s status. They slide into the grooves on the gripper.

Pick-and-Place Grippers with Adjustable Force Control

Image of Product. Front orientation. Pick-and-Place Grippers. Magnetic Air-Powered Pick-and-Place Grippers, Pick-and-Place Grippers with Adjustable Force Control.

Grippers with adjustable force control help prevent damage and accidental pickups. Turn the bolt at the top of these grippers to adjust the distance between the magnet and your part. Move the magnet away to reduce the magnetic force for delicate and lightweight parts or move it closer to increase the force for heavy parts.
