## Description

Outdoor enthusiasts rejoice! Adafruit now have standard 5.5/2.1mm DC power cable sets in a waterproof variety. These cable sets are ideal for projects that must weather the weather: dust, water, rain, snow, tornado (not volcano proof!). They are a little bulkier than normal DC jacks because of the o-ring and removable over-screw. The o-ring is what makes the waterproof seal, and the over-screw keeps the two halves connected solidly
 
 Comes as a set of two cables - one plug and one jack. The total length of the connected cables is 16" (40cm). The wires are color coded - red is center, black is ring - to match the most common center-positive polarity.

## Technical Details

- Each half has a 7" long cable (not including the connector part)
- 16" total length when plugged together
- 5.5mm / 2.1mm 'standard' DC jack with coloring for center positive wiring
- 0.68" (18mm) diameter at widest point
- 0.172" (4.4mm) thick cable
- 20 grams per set
- IP67 rated
- PVC Connector & Jacket
