Continuous glucose monitoring with Guardian 2 Link Transmitter

The Guardian 2 Link transmitter is a component of Medtronic's CGM systems. It connects to the glucose sensor and sends glucose data wirelessly to the MiniMed® 640G insulin pump. It’s very small – but it makes a big difference


  • Small & lightweight: 3.5 x 2.8 x 0.7cm (1.4" x 1.1" x 0.3") and less than 7g (1/4 ounce)
  • Shaped to move with you - it won't tug, pull, or pinch
  • Small footprint: 3.8 x 2.0cm (1.5" x 0.8") – about the size of a postage stamp



About the size of a 2 pence piece, with an ultra-sleek thin profile, the Guardian 2 Link transmitter lies almost flat, with no bulge. Wireless transmission means that it works under any clothing.



You can wear the transmitter and glucose sensor while swimming, bathing, or showering. Fully immersible, you can wear it to a depth of 2.4 metres (8 feet) for up to 30 minutes.

Up to 10hrs of data backfill

If the sensor connection is lost, the transmitter will store up to10 hours of data which will be displayed upon re-connection to the pump.

Guardian 2 Link transmitter is only compatible with the MiniMed® 640G insulin pump.
MiniLink transmitter is compatible with the MiniMed® Veo system and Guardian® REAL-Time CGM system.
