Designed with versatility in mind, the S PB 644 series supports efficient operation in machinery and control panels. This continuous flex PUR Profibus-DP cable with colored conductors or pairs and tinned copper braid shielding is optimized for use in cable tracks. Rated for 300 V and up to 70°C, it features a rough-surface PUR TMPU jacket (EN 50363-10-2) that provides durability and resistance in harsh industrial conditions. Certified to CE and RoHS standards, the S PB 644 series meets key international requirements. Offering excellent oil and weather resistance, this halogen-free cable is engineered to perform in demanding environments such as the chemical and petrochemical industries. Highly flexible and drag chain-compatible, it ensures intrinsic safety and reliable bus supply of field devices, minimizing downtime and maximizing productivity.
