Through-hole slip ring DHK030-12-5A

through-borehollow-shaftfor thermocouples

Short Description
DHK030-12-5A thermocouple conductive slip ring from INGIANT. High-performance through-bore rotary connector with 30 mm bore, 12 circuits (6×5A heating power + 6×5A thermocouple signal), gold contacts, dynamic contact resistance ≤10 mΩ and IP51 protection, designed for simultaneous transmission of heating power and precise temperature signals in rotating industrial systems.

Product Detail
The DHK030-12-5A is a through-hole slip ring engineered for continuous 360° rotation while delivering both heating current and thermocouple signals. Its 30 mm hollow shaft and 12 dedicated channels use gold-to-gold contact technology to minimize contact resistance and electrical noise, ensuring stable temperature measurement in demanding factory environments. Suitable for integration on rotary furnaces, packaging machines and automated production lines where shaft or cable passage is required.

Core Features & Advantages

• Reliable thermocouple signal integrity with dedicated shielded twisted-pair cables to suppress electromagnetic interference and gold contacts to prevent oxidation-related drift.
• Dual-function transmission combining 6 circuits for 5A heating power and 6 circuits for thermocouple signals in a single compact through-hole unit, simplifying wiring and eliminating tangling on rotating shafts.
• Industrial-grade construction: aluminum alloy housing and IP51 protection for dust and moisture resistance in production environments.
• Through-bore design allows shaft, pipe or cable passage, making it ideal for rotary furnaces, packaging machinery and automated lines.
• Customizable lead lengths, wire types and circuit configurations to match specific application requirements.

Applications

• Industrial rotary heating furnaces and ovens
• Automated production lines with rotary workstations
• Food processing and pharmaceutical manufacturing equipment
• Rotary packaging machinery with heating modules
• Testing instruments requiring multi-channel temperature monitoring

Quality & Support
