The KR SightLink E3040 Omni 30 cm adds a camera, light, sensor, or monitor to an extrusion machine cell you already have - without rebuilding the frame. It secures with T-nuts to 20x20, 30x30, or 40x40 extrusion (for example, a 50 cm inspection cell built from 30x30 profile), gives you a controlled Omni arm to position the device, and ends in a standard ¼"-20 screw.

The Omni gives full 360° rotation and a 90° pivot for precise aiming, with an interchangeable ball-head socket at each end and anti-slip rosettes that lock the joint so a set angle holds without creeping. A ratcheted handle makes locking quick. At 30 cm / 11.8 in it's the middle Omni length - more reach than the 20 cm, with more stiffness and load margin than the 40 cm. Choose it when the 20 cm can't quite reach the target but you don't need the longest arm.

This is the flexible-arm route - a positioning and tuning tool for integrators, not a production mount. Use it to find and prove the right camera and light positions; once the layout is locked, switch to the SightLink rosette-tooth / square-coupler version for a fixed, repeatable production mount.

When the machine cell already exists, you don't want to rebuild it to add a camera - and a one-off bracket locks you into one position before you've proven it. SightLink lets you mount onto the existing extrusion, tune the camera and light while the inspection is still being dialed in, and reconfigure by moving the arm instead of remaking a bracket.

This is a setup and positioning tool, not the production mount. An integrator uses it to get a camera and light onto a customer's cell quickly, find the right positions, and prove the inspection. A factory machine-vision team uses it the same way - to dial in the geometry on the cell. Once those positions are locked, the rosette/square-coupler version provides the fixed, repeatable mount a production line needs.

This kit is the middle link of the chain - it connects your existing 20x20 / 30x30 / 40x40 extrusion cell to your device's ¼"-20 thread, base and arm included:

¼"-20 is the common camera/accessory thread. "Male" means this kit provides the screw; your device or adapter plate needs the matching female thread. If the image must stay level and can't twist on a single screw, add a locating pin or anti-rotation plate.

Choose Omni when you want a repeatable, locked angle - its anti-slip rosettes index to a set tooth position and return to it, so a camera holds the angle you set. Choose Super Knuckle when you want fast, freehand positioning - its friction ball joints glide smoothly to any angle and lock with a single knob, and it offers a wider range of accessories. They simply hold differently: the Omni for an exact, repeatable angle, the Super Knuckle for quick, free movement.

This Omni reaches 30 cm / 11.8 in and carries up to 6 kg / 13.2 lb close to the clamp - a balanced reach in the Omni range - derating as the payload moves toward the tip or off-center. It locks to a repeatable indexed angle for static positioning and is not vibration-rated, so re-check the hold after heavy use.

• Reach: 30 cm / 11.8 in nominal.
• Close-in working load: up to 6 kg / 13.2 lb.
• Best for: machine-vision cameras, lights, sensors, monitors, and accessory plates that need a mid-range reach.

Start with the shortest arm that reaches the target. The shorter Omni is cheaper, carries more load, and holds the image steadier - so reach for 30 cm only when 20 cm can't get to the target. The 6 kg figure is a close-in reference for the arm; usable load still depends on payload position, mounting angle, vibration, and cable pull. Secure the cable to the frame before judging stability - cable drag can shift a camera even within the load range.

This kit is at its best for mid-reach camera and light positioning on an extrusion cell you already have, where you can tune and prove the vision setup before locking it down.

• Adding a camera and light to an existing 20x20 / 30x30 / 40x40 extrusion cell.
• Retrofitting vision onto a machine frame without rebuilding it.
• Pilot and pre-production inspection on a real machine cell.
• Integrator demos that show vision working on the customer's own frame.
• Cable-managed setups within the arm's load range.

The kit ships as three parts - the extrusion base, the 30 cm / 11.8 in Omni arm, and the ¼"-20 male device screw - and nothing device-specific.

• SightLink E3040 extrusion base (T-nut mount) for 20x20 / 30x30 / 40x40 profile.
• Omni 30 cm / 11.8 in adjustable arm.
• ¼"-20 male device screw.

Not included unless bundled: the extrusion frame or machine cell; the camera, lens, light, sensor, monitor, or controller; a camera-specific adapter plate; machine guarding; and cable strain-relief hardware.

Before ordering, confirm four things: your extrusion size (20x20 / 30x30 / 40x40), a ¼"-20 female device thread, payload and cable pull suited to a 30 cm / 11.8 in reach, and a reviewed path if the setup is vibration-prone or production-bound.

• Confirm the extrusion is 20x20, 30x30, or 40x40 with a slot/face the E3040 base can land on, and enough clearance for the base, arm sweep, device body, connector, and cable bend radius.
• Your device needs a ¼"-20 female thread, or an adapter plate that gives it one.
• Check that payload weight, center of gravity, and cable pull suit the 30 cm reach.
• This flexible-arm kit is for positioning and testing, not production. For a released production mount, use the SightLink rosette-tooth / square-coupler version.
