Stop Worrying About Cables Melting or Cracking in Harsh Environments
You have a big problem. Your factory floor gets incredibly hot. Or maybe it is freezing cold outside. You have chemical spills and oil leaks. Standard cables crack, peel, or stop working when things get tough. You lose signal. Your control systems fail. You have to stop the line to fix wires. This costs you money and time. You need a cable that does not quit. You need a cable built for the real world. The Belden 83703 is that cable. It is tough. It handles extreme heat and cold. It resists chemicals. It keeps your signals clear even when the environment tries to destroy it. This is not a cheap wire. It is a professional-grade tool for serious industrial use.
What Makes Belden 83703 the Best Choice for Your Control System?
This cable is not just a piece of copper. It is a complete system designed to protect your data and power. It uses premium materials. The conductors are stranded tinned copper. This means they do not rust. They stay shiny and conductive even in wet conditions. The insulation is FEP. This is Teflon. It does not melt at high heat. It stays flexible in deep cold. The jacket is also FEP. This double protection is rare. Most cables use PVC or cheaper plastics. They get sticky when hot and brittle when cold. Belden 83703 stays strong from -70°C to 200°C.The shielding is top-class. It uses a combination of aluminum foil and a tinned copper braid. The foil blocks 100% of high-frequency noise. The braid blocks 85% of low-frequency noise. This is critical for low-voltage signals like 4-20mA or 0-10V. If you have motors or heavy machinery nearby, they create electrical noise. This cable stops that noise from messing up your sensor readings. Your data stays accurate. Your process stays in control.
Detailed Technical Specifications You Can Trust
Here are the hard numbers. You need to know exactly what you are buying.
- Part Number: 83703 (Also known as 83703-002500 or 83703-002100)
- Conductor: 3 Conductors, 16 AWG (American Wire Gauge)
- Stranding: 19 strands per conductor (19×29)
- Material: Tinned Copper (resists corrosion)
- Insulation: FEP (Fluorinated Ethylene Propylene / Teflon)
- Shield: Aluminum Foil Tape (100% coverage) + Tinned Copper Braid (85% coverage)
- Outer Jacket: FEP (Teflon)
- Voltage Rating: 300 Volts
- Temperature Range: -70°C to +200°C (-94°F to 392°F)
- Fire Rating: CMP (Plenum), UL 910, FT6
- Diameter: 0.206 inches (5.28 mm)
- Weight: 46 lbs per 1000 feet
- Bend Radius: 2.1 inches (stationary and installation)

These specs mean this cable is small enough to fit in tight spaces but strong enough to handle industrial abuse. The 300V rating is perfect for most control circuits. The temperature rating is massive. Most cables fail at 105°C. This one works at double that temperature.
Where Should You Use This Cable?
You can use this cable almost anywhere, but it shines in the toughest spots.
Industrial Automation and Control
This is the home turf for Belden 83703. Use it for PLC (Programmable Logic Controller) wiring. Connect your sensors to the control panel. Use it for DCS (Distributed Control Systems). It is perfect for 4-20mA current loops. These are the standard signals in factories. The shielding prevents the loop from drifting. You get accurate readings every time.
Extreme Temperature Zones
Do you have a foundry? A bakery oven? A cold storage warehouse? This cable works in all of them. In a heat treat oven, standard PVC insulation would melt and short out. Belden 83703’s FEP jacket laughs at the heat. In a freezer, PVC cracks if you bump it. FEP stays flexible. You can install it and forget it.
Chemical and Outdoor Exposure
If you run cables outside, UV rays destroy plastic. FEP resists UV. If you have oil spills or acid fumes, standard cables absorb the chemicals and swell up. Belden 83703 is chemically inert. It does not absorb oils or solvents. It is also rated for direct burial. You can put it in the ground without conduit if local codes allow. It resists moisture and gas.
Audio and Voice Communications
This cable is not just for data. It works for professional audio too. The twisted pairs keep the audio signal clean. The high shielding stops hum and buzz from nearby power lines. Use it for paging systems, intercoms, or low-voltage voice lines in noisy factories.
Compliance and Safety Standards
Safety is not a joke in industrial settings. You need cables that meet strict codes. Belden 83703 checks all the boxes.
- UL Listed: It meets UL 910 and UL 1581 standards.
- CSA: It is C(UL) certified for Canada.
- NEC: It is rated for use in plenum spaces (air handling spaces) per Article 800. This means if there is a fire, it does not spread toxic smoke.
- European: It has the CE Mark. It meets RoHS 2 and REACH directives. It does not contain harmful heavy metals.
- China: It meets China RoHS II (GB/T 26572-2011).
Having these certifications makes your job easier. You do not have to worry about the inspector rejecting your wiring. You install it, and it passes inspection the first time.
Why Buy Belden 83703 Instead of Generic Alternatives?
You might find cheaper cables online. They claim to do the same thing. But they cut corners. They might use PVC instead of FEP. They might skip the copper braid and only use foil. They might use bare copper that rusts.Belden is a legacy brand. They have been making cables since 1902. They know what works. When you buy Belden 83703, you are buying consistency. Every foot of wire is tested. The electrical properties are guaranteed. The capacitance is low (35 pF/ft). This means the signal travels fast and clear over long distances.Cheap cables have high capacitance. This acts like a filter. It slows down your signal. Your response time gets laggy. In a high-speed production line, lag costs money. Belden 83703 keeps your response times sharp.Also, look at the construction. The conductors are 19×29 stranded. This makes the cable very flexible. It is easy to pull through conduit. It is easy to terminate. You do not need special tools. A standard crimper works fine. The tinning on the copper makes soldering easy. The solder flows smooth and fast.
