The Workhorse Cabling Built for Hostile Agricultural Control Environments.

If you are running digital climate sensors (like the DHT22/AM2302) or low-voltage control setups over custom distances, standard thin telephone wire or speaker cable isn’t going to cut it. High-humidity mushroom fruiting rooms and urban farm setups are notoriously harsh environments that cause rapid copper rot, voltage drops, and dropping signal data.

This Bundu Teq 22AWG 4-Core Stranded Cable is explicitly selected to solve that problem. Built with a robust, highly flexible black PVC outer jacket, it handles runs from 1m up to 10m+ effortlessly without sacrificing digital communication accuracy.

Why Tinned Copper Matters

Raw copper oxidizes rapidly when exposed to constant moisture, eventually causing data drops, “NAN” errors on your controllers, or complete sensor failure. Each core in this premium cable contains 17 strands of precision tinned oxygen-free copper. The uniform tin-coating acts as an impenetrable barrier against corrosion and rust, while simultaneously making the wire incredibly easy to strip and solder directly onto breakout pins.

Technical Specifications:

• Wire Gauge: 22 AWG (4 Conductor / 4 Core)

• Conductor Layout: 17 Strands x 0.14mm per core

• Internal Wire Colours: Red, Black, Yellow, White

• Outer Insulation Material: Flame-Retardant PVC (VW-1 & FT1 Rated)

• Voltage Capacity: Rated up to 300V Max (Perfect for DC 5V / 12V / 24V Logic Control Systems)

• Current Capacity: Safe up to 4A–5A Max

• Thermal Working Range: -20°C to 80°C

Perfect For:

• Extending digital humidity and temperature sensor arrays (DHT22, AM2302, DS18B20) over long distances.

• Rewiring legacy MH13001 or Sonoff TH controller setups to combat sensor failure.

• Wiring low-voltage relays, solenoids, smart IOT circuits, and custom CO₂ controllers.

• Any DIY automation project that demands real protection from moisture and current breakdown.

Note: This wire is sold and cut strictly per metre. Enter the total number of metres you need as the item quantity, and we will ship it out as a single, continuous uncut spool.
