About Durometer Hardness Scales

Snap these grommets into place to hold wire, cable, and cords in wet locations and form a seal against dust, debris, and water. Two flanges create a seal when pulled through holes in your enclosure, so you can install these grommets without tools. They are made of TPE rubber, which won’t break down under UV exposure. Rated UL 94 V-0, these grommets will stop burning within 10 seconds if ignited.

Grommets with an IP54 rating protect against dust and splashing water from all directions. IP67 rated grommets protect against dust and temporary submersion.

Add a cable tie to grommets with a cable tie attachment point to relieve strain and extend the life of your cable, wire, and cords. These grommets also have closed front sides, so they can be used as hole plugs.

Shaft Grommets

Support shafts, bearings, and other moving parts that are routed through a hole. These grommets are slippery to allow parts to move freely in the hole. Install them on thin sheet-metal panels. All of the grommets are split, which makes them easy to snap into place while also allowing them to expand if they heat up or absorb moisture. Made of plastic, they are chemical resistant and won't dry out and become brittle when exposed to UV rays. All have an extra-hard rating to withstand high levels of impact. They can be used outdoors.

Grommets with MDS reinforcement have added wear resistance.

Contact-Sensing Robot Safety Padding

Cover robot arms and tools with this padding to help prevent injuries in areas where people are working nearby. When the padding is touched, pressure sensors signal your machine to stop moving, halting it within nine milliseconds. If a collision takes place, the soft polyurethane foam will lessen the impact. With this padding installed, you can operate robots closer to people and at higher speeds than with other safety equipment, such as machine guards. You can also combine it with other equipment to create multi-step safety systems.

Each pad has LEDs that change color to indicate their status. When the lights are blue, the padding is fully operational. Pads that sense a pressure change turn red and the surrounding pads turn yellow, clearly showing the impact area. They're powered by internal micropumps, so you don't need an outside compressed air source. The double circuit design makes sure that if one circuit fails, the other will continue to function.

All components meet international design standards for safety. Using this padding helps you meet ISO/TS 15066 standards for safe interactions between humans and robots. Before running robots, you should carry out a safety risk assessment as described in ANSI/RIA R15.06 to ensure a safe environment for those working near the robot.

Modular Padding

Modular Padding

To build your own safety assembly, use modular padding. It's often used with carriages, guide rails, and automatic guided vehicles (AGVs). While it's ideal for unique designs, this padding takes up more space than custom-fit padding, and is harder to install. Pads are sold individually, and you'll need a separate controller for every 15 pads. Each pad consists of a base and a foam layer, which connect to each other with magnets. Screw the base onto your part (mounting fasteners not included), then attach the foam to the base.

Flanges

Flange senses pressure in any direction through the robot tool as well as direct contact with the flange itself.

Flange

Flanges are compatible with most robot tools and accessories, so you can switch out different tools without needing custom fit padding for each one. However, flanges are not as sensitive as custom-fit padding, and they extend the length of your robot arm. They come with a controller, cables, and adapters that match several common mounting patterns. If you don't see your robot model number listed, measure the bolt circle diameter to determine mounting compatibility.
