3M 3811 Series Flat Cable, 50 Conductors, 30.48m Length - 3811/50 (100'

This flat cable is designed to provide organised multi-conductor connections in industrial and electronic assemblies. It delivers flexible interconnection for equipment requiring compact, parallel conductor layouts and is suited to environments where repeated movement and space-efficient routing are needed.

Features and Benefits:

• 50 conductors enhance multi-signal routing capacity
• 26AWG stranded construction improves bend endurance
• Tin-plated copper conductors reduce contact oxidation risk
• PVC multi-colour jacket enables quick polarity and signal identification
• Rated to 300V for low-voltage control and signal systems
• Hi-Flex design withstands frequent flexing at elevated temperatures

Applications

• Suitable for ribbon-to-connector interconnects in automation cabinets
• Ideal for harnessing multiple control signals in production equipment
• Used for internal wiring of test rigs and assembly jigs
• Can be used for multi-conductor connections in robotics cable chains

How does the cable cope with repeated flexing in dynamic applications?

It uses stranded 7-core conductors and a Hi-Flex construction to tolerate continual movement without Rapid conductor fatigue.

What flame and vertical propagation behaviour does it exhibit?

The cable meets FT1 and VW-1 classifications to limit flame spread in the respective regional test regimes.

What operating temperatures can be expected in service?

The jacket and conductors are specified for continuous operation up to 105°C and down to -20°C.

How long is the supplied reel and how does that affect installation runs?

The cable is supplied as a single 30.48 m length enabling extended continuous runs without jointing.

Is the cable screened for EMI-sensitive circuits?

The construction is unscreened, so external screening or grounded routing should be used where electromagnetic immunity is required.
