Proteus Services Examples


Proteus Industries specializes and excels at providing customer requested customization which may include: fittings, special cables and connections, brackets and specialized calibrations including viscosity compensation.


The 8000RFR Series

Custom designed for a customer to use in harsh (>1100GHz) EMI or RF environments. The 8000RFR has been laboratory tested up to an RF power of 10v/m to 10GHZ (maximum laboratory testing available). Effective design indicates that this device is capable for up to 1181 GHz.

Resistant to (IP67 or IP68) Wet Environments​​


98008SA6F3P1: Some of our customers require our products to be used under extreme temperature conditions.

For this purpose, Proteus can supply a closed-cell foam insulator to prevent icing in cold conditions or protect workers from burns in higher temperatures.
