Sensor Extension Cables

Smart Sensor Extension Cables for HOBO Weather Data LoggersSmart Sensor Extension Cables can be used individually, or be connected together to facilitate optimal sensor placement. Available in 5 m, 10 m and 25 m lengths (16.4', 32.8' and 82' respectively), the Smart Sensor Extension Cables have anti-snag protectors over the tab on the RJ11 connectors and are compatible with HOBO Weather Station smart sensors as well as the external sensors for the HOBO U14-002 Data Logger

Smart Sensor Extension Cables add to the length of a HOBO Weather Station's smart sensor cable and count towards the 100 m cable length limit for each logger. A weatherproof housing (S-EXT-CASE) is required for all connections that will be outside or in condensing environments. 

Weight: 5 m cable: 88 gms (3.1 oz); 10 m cable: 176 gms (6.2 oz); 25 m cable: 440 gms (15.7 oz)

2m Extension Cable: S-EXT-M002, $20.00
5m Extension Cable: S-EXT-M005, $28.00
10m Extension Cable: S-EXT-M010, $33.00
25m Extension Cable: S-EXT-M025, $50.00
Weatherproof Housing: S-EXT-CASE, $30.00
