QL xxxx SBQ TPC 600V Multi-Core Sensor Cable Tinned Copper Shielded ETFE Sheathed Wire

The QL xxxx SBQ TPC Series represents a premium class of 600V Multi-Core Sensor Cable designed for the most demanding aerospace, defense, and industrial applications. Unlike standard cables, this series features a specialized "Double ETFE" construction, utilizing extruded ETFE for both the primary insulation and the outer jacket. This dual-layer approach provides exceptional resistance to cut-through, abrasion, and harsh chemicals (including Skydrol and jet fuel).

Engineered to meet the rigorous dimensional and electrical requirements of SAE-AS22759 and NEMA-WC27500, the series integrates a braided tinned copper shield to ensure 100% coverage against electromagnetic interference (EMI).

The series provides tailored solutions for complex circuit requirements: the SBQ1 delivers robust single-core power transmission; the SBQ2 utilizes twisted geometry for high-noise immunity; the SBQ3 ensures balanced impedance for sensor inputs; and the SBQ4 maximizes conductor density for multi-signal applications.

Rated for continuous operation from -90°C to +155°C, the QL xxxx SBQ TPC Series ensures reliable performance in both cryogenic and high-heat zones, making it the definitive choice for mission-critical wiring.

• Aerospace-Grade Standard - Manufactured in strict accordance with SAE-AS22759 and NEMA-WC27500 specifications, ensuring the highest level of quality control and reliability.
• Double ETFE Construction - Features extruded ETFE insulation over the conductor and an extruded ETFE jacket. This combination offers superior mechanical properties, including high tensile strength and resistance to lubricating oils and coolants, compared to standard PVC cables.
• Superior Shielding - The braided tinned copper shield provides excellent conductivity and protection against electromagnetic interference, while the tin plating prevents corrosion and aids in solderability.
• Extreme Temperature Resilience - Rated for continuous operation from -90°C to +155°C, making it suitable for environments ranging from high-altitude freezing conditions to near-engine heat zones.
• 600V AC Rating - Robust voltage rating suitable for main power distribution and critical control circuits.

*The same conductor sizes are available in SB2 (twisted pair), SB3 (twisted triple) and SB4 (twisted quad). Custom core counts are available*

Aerospace & Avionics - The SAE-AS22759 standard and ETFE jacket make this sensor cable ideal for airframe wiring, flight control systems, and avionics bays where weight reduction and fluid resistance are critical.

High-Performance Motorsports - Used in engine harnesses and data logging systems. The braided tinned shield protects sensitive telemetry data from alternator and ignition noise, while the ETFE withstands under-hood heat.

Industrial Robotics - Perfect for the "7th axis" or tooling ends of robots. The double ETFE construction resists the abrasion caused by constant flexing and the oils used in gearboxes.

Oil & Gas Exploration - Suitable for downhole sensors and surface instrumentation. This sensor cable resists drilling muds, acids, and the high temperatures encountered in extraction processes.

Tactical & Defense - Reliable for ground vehicles and naval vessels. The tinned copper components prevent corrosion in saltwater environments, and the robust jacket withstands rough handling.

Railway & Transit - Used in train control and signaling. The cable meets the mechanical durability requirements for under-carriage wiring exposed to ballast impact and weather.

Q: Why is the insulation and jacket both ETFE?
A: Using ETFE for both layers prevents delamination. Since the materials are chemically similar, they bond well, creating a cable that is more resistant to mechanical stress and fluids than a hybrid (e.g., ETFE/FEP) cable.

Q: Is the shield spiral wrapped or braided?
A: The document specifies a braided shield. Braiding offers better coverage (typically >90%) and mechanical strength compared to spiral wrapping, though it is slightly less flexible.

Q: What is the dielectric strength?
A: While the working voltage is 600V AC, the ETFE insulation allows the cable to withstand a spark test voltage significantly higher (typically 1500V to 3000V depending on the specific gauge) to ensure pinhole-free insulation.

Q: How does this compare to MIL-W-22759 wire?
A: SAE-AS22759 is the updated standard that superseded MIL-W-22759. This sensor cable is the direct modern equivalent, offering improved material consistency and performance metrics.

Q: Is the jacket smooth or textured?
A: The extruded ETFE jacket on this sensor cable is typically smooth, which aids in pulling the wire through conduits and harnesses.

Q: Can I mix different gauges in one order?
A: Yes, we support consolidated shipping. You can order multiple part numbers in a single shipment to save on freight costs.
