Pegasus Astro USB 3.0 Type-A to Type-B Cable

Product Overview

This is the Pegasus Astro USB 3.0 Type-A to Type-B cable range, offered in six configurations covering premium shielded leads, metal-shell versions, and two-packs of shorter cables. Type-A to Type-B is the standard pairing for astronomy cameras, powerboxes and powered USB hubs, and these are built to be dependable in the one place a generic cable tends to fail — cold, damp, and being flexed by a moving mount.

Choose the configuration that matches the run you need. All six carry USB 3.0 SuperSpeed signalling at 5 Gbps.

Who It's For

This is a good match if you:

• Connect a cooled CMOS camera, powerbox or USB hub that uses a Type-B socket.
• Want short, tidy runs on the imaging train rather than coiling excess cable on the mount.
• Need spares in the field — the 0.3 m and 0.5 m options ship as two-packs for exactly that.
• Have had a cheap cable fail mid-session and want shielding and strain relief built for outdoor use.

Key Features & Design

• USB 3.0 SuperSpeed: 5 Gbps throughput across every configuration, suitable for large-sensor downloads.
• Type-A to Type-B: the standard astronomy camera and powerbox pairing.
• Metal-shell options: the 1.0 m and 0.5 m metal versions add a machined connector housing for repeated plugging and unplugging.
• Premium shielded options: the 1 m and 2 m premium leads use heavier shielding for longer runs near motors and dew heaters.
• Two-packs at short lengths: 0.3 m and 0.5 m ship as pairs, which is the usual requirement when wiring a hub to two devices.
• Backwards compatible: works with USB 2.0 devices at USB 2.0 speed.

Recommended Uses

• Camera to powered USB hub on the telescope, using a short 0.3 m or 0.5 m lead.
• Powerbox or hub to control PC over a 1 m or 2 m premium run.
• Replacing a failed or intermittent cable in an existing observatory installation.
• Field spares kit, where the two-packs are the practical choice.

Compatibility and Accessory Notes

• Connector check: Type-B is the squarer connector used on most cooled astronomy cameras, Pegasus powerboxes and the USB Control Hub. Confirm your device is not Type-C or Micro-B before ordering.
• Pairs with Pegasus powerboxes and the USB Control Hub, all of which accept Type-B upstream.
• For runs beyond about 5 m, a passive cable becomes unreliable — the Pegasus active USB extension range covers 5 m, 15 m and 20 m instead.
• Camera enumeration: some QHY and ZWO USB 3 cameras negotiate over USB 2.0 first. That is a camera behaviour, not a cable limitation, and these cables support it.

Good to Know Before You Order

• Two of the six options are two-packs. The 0.3 m and 0.5 m black versions ship as pairs; the premium and metal options are single cables. The variant name states which.
• These are passive cables. Above roughly 5 m you want an active extension — we stock those separately and are happy to advise on the right length.
• Data only. USB bus power is carried, but your camera or controller still needs its own 12 V supply.
• Metal shell versus premium is a housing difference, not a speed difference. Both run at 5 Gbps; the metal shell simply survives more insertion cycles.

Frequently Asked Questions

Is it difficult to set up?

No. It is a cable — Type-A to the computer or hub, Type-B to the device. No drivers, no configuration.

Which length should I choose?

Short 0.3 m or 0.5 m leads for camera-to-hub on the telescope; 1 m or 2 m premium for hub or powerbox back to the control PC. If the run is longer than about 5 m, use an active extension instead.

What is the difference between premium and metal shell?

Premium refers to heavier shielding; metal shell refers to the connector housing. Both are USB 3.0 at 5 Gbps.

Are the two-packs two identical cables?

Yes — two cables of the same length in one package.

Will these work with USB 2.0 devices?

Yes, at USB 2.0 speed.

Bottom Line

In short: dependable USB 3.0 Type-A to Type-B cables in six configurations, from 0.3 m two-packs for the imaging train up to 2 m premium runs. Pick the length for the job and, past about 5 m, move to an active extension.
