The KR VisionFrame 35 Max Arm 53 cm reaches a camera or light far out from a freestanding 35 mm post frame and locks and holds its set angle. It mounts to a vertical 35 mm VisionFrame post with a Super Convi clamp - the jaw grips the post and the hex receiver locks the arm's 5/8" (16 mm) stud with a spring-safety catch - then gives you the longest controlled arm in the family, ending in a standard ¼"-20 screw.

The Max Arm is a multi-position arm: 90° pivoting, 360° rotating ends, and 360° elbow rotation. A center ratcheted handle controls and locks all three movements at once, and anti-slip rosettes hold the set angle so it doesn't creep - you can place a camera or small light exactly where you want it, even in an awkward spot. At 53 cm / 20.8 in it gives the longest reach in the VisionFrame 35 family.

One honest note: the Max Arm is a substantial arm (about 1 kg / 2.2 lb on its own), so at full extension its own weight and leverage can introduce some drift. In machine vision that's rarely a problem - inspection cameras are light - but for a heavier payload, keep it closer to the post or use a stiffer support.

VisionFrame 35 is a larger prototyping and integration frame - the route for testing bigger camera-to-product geometry, taller camera positions, and multi-camera layouts before the final machine is built. The camera, light, sensor, adapter plate, and cable management are chosen separately, so you build the exact setup your scene needs.

When the inspection scene is too big for a tabletop - taller camera positions, more camera-to-product distance, a larger sample, or a conveyor-style mockup - VisionFrame 35 gives you a freestanding 35 mm post frame to build on. Clamps slide up and down the post, so you can move a camera or light to a new height without cutting a custom frame.

This is a prototyping and integration frame, not a production station. An integrator uses it to stand up larger geometry fast, prove the inspection, and show a customer. Once the layout is locked, the production path becomes a VisionCell inspection cell, a SightLink E3040 retrofit onto a real machine frame, or a custom engineered fixture.

This kit is the middle link of the chain - a Super Convi clamp grips your 35 mm VisionFrame post and the Max Arm carries your device's ¼"-20 thread, clamp 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 the Max Arm when you need reach beyond the Omni 40 cm or Super Knuckle 23 cm (9 in) and still want a firm, lockable hold. Its ratcheted handle and anti-slip rosettes lock all three movements at a set angle, so it positions precisely rather than just dangling out far - useful for a camera over a wide scene or a light at an awkward angle. For a short, stiff camera hold, an Omni still wins; the Max Arm is the tool when the geometry is simply too big for the shorter arms.

This is the longest arm in the VisionFrame 35 family at 53 cm / 20.8 in, and it carries up to 4 kg / 8.8 lb close to the post - that figure is a close-in reference, not a rating at full reach: the arm's own ~1 kg / 2.2 lb weight and the leverage of full extension reduce what it holds steadily and add some drift, so keep the payload light and reach only as far as the scene needs.

• Reach: 53 cm / 20.8 in - the longest VisionFrame 35 arm.
• Close-in working load: up to 4 kg / 8.8 lb.
• Best for: machine-vision cameras and small lights that need to reach across or around a larger scene and lock precisely.

The 4 kg figure is a close-in reference. At 53 cm the arm's own weight and the leverage of full extension reduce what it holds steadily and can add a little drift - so lock it down, keep the payload light, and reach only as far as the scene needs. Machine-vision cameras are light enough that full reach is usually fine; a heavier light or monitor should stay closer to the post. Secure the cable to the post before judging stability - cable drag can shift the image even within the load range.

Use the Max Arm 53 cm when the device has to reach where shorter arms can't:

• Reaching a camera or light across or around a larger sample.
• Top-down or steep-angle views over a wide VisionFrame 35 scene.
• Precise, lockable positioning that still needs long reach.
• Lighting placement at awkward angles for inspection, video, or demos.
• Cable-managed setups within the arm's load range.

The kit ships as three parts - the Super Convi clamp, the 53 cm / 20.8 in Max Arm, and the ¼"-20 male device screw - and nothing else; the 35 mm post and the device are separate.

• Super Convi clamp (ratcheted handle) for a vertical 35 mm post - jaw fits 12-51 mm bar, hex receiver with spring-lock safety.
• Max Arm 53 cm / 20.8 in - 90° pivot, 360° rotating ends, 360° elbow, ratcheted lock with anti-slip rosettes.
• ¼"-20 male device screw.

Not included unless bundled: the VisionFrame 35 post or frame; the camera, lens, light, sensor, monitor, or controller; a camera-specific adapter plate; and cable strain-relief hardware.

Before ordering, confirm a 35 mm VisionFrame post, a ¼"-20 female device thread, a light payload kept as close as the scene allows, and a reviewed path if the setup is vibration-prone or production-bound.

• Confirm you have (or are buying) a 35 mm VisionFrame post for the clamp to grip - this mount is not for 16 mm VisionGrid rail, 22 mm VisionGrid tube, or 3030 / 4040 extrusion.
• Your device needs a ¼"-20 female thread, or an adapter plate that gives it one.
• This is a long, substantial arm - lock it down and keep heavier payloads close to the post; machine-vision cameras are light enough that full reach is usually fine.
• Weight or secure the post base, and re-check the clamp's grip on the post after loading - a tall freestanding frame can sway, and a long arm makes a clamp more likely to creep down the post under load or vibration.
• For a released production line - not a prototype - use VisionCell, a SightLink E3040 retrofit, or a custom fixture.
