Schneider Electric AvatarOn E8332TDRJS5_GH in color metal gold hairline is a 2 gang data socket with 1 telephone interface and 1 RJ45 Cat5E, Cat3 interface. The dielectric strength level, namely the voltage that the material this data socket uses can withstand for a given wall thickness before dielectric breakdown or electrical discharge, is 1000. 23 dB is the return loss of this device, namely the loss of power in the signal reflected by a discontinuity in a transmission line used. It is 86 mm in width, 86 mm in height and 40.7 mm in depth. And the embedding depth is 31 mm. This telephone and internet data socket enables both flush and surface mounting. PC (polycarbonate) material makes it as resistant and lasting as possible. It resists to UV radiation as well. Besides, it meets the following standards,ASTMD4566-98, TIA/EIA-568-B.2-1.
