BLASI – Helix cable
The BLASI helix cable is a coiled, stretchable power and signal cable designed for rotating components in revolving door systems. This spiral cable extends and retracts with canopy rotation while maintaining reliable connections to slip rings or rotary joints in K21 and K41 series doors. Flexible construction prevents fatigue from millions of flex cycles. Pre-terminated connectors match controller boards and motor drives precisely. The BLASI helix cable ensures uninterrupted power delivery and control signals during continuous 24/7 operation in high-traffic commercial entrances.
Product Details
The BLASI helix cable provides dynamic connectivity for rotating drive assemblies in automatic revolving doors. Its tightly coiled PUR jacket stretches up to three times resting length while protecting multi-conductor power and signal lines from abrasion against canopy walls. Stainless steel strain relief at both ends secures terminations against centrifugal forces during high-speed rotation.
Technicians install the BLASI helix cable between fixed controller boards and rotating motor mounts in two-wing K21 and four-leaf K41 systems. Factory-engineered coil geometry matches OEM rotation patterns, preventing over-extension damage common in generic spiral cables. Gold-plated contacts maintain low-resistance paths for 24VDC logic and encoder feedback essential for precise leaf synchronization.
