• 16 AGW, stranded, shielded, PVC, energy-chain rated

• limit switch, proximity switched, relay control, e-stop

– Non-defined, twisted pair• 16 AGW, stranded, twisted pair, shielded,

energy-chain rated• Differential digital signals (TTL), differential

analog– Coaxial 50

• RF, audio, single highly-modulated signal (clock)– Coaxial 75

• Video
