About Wire and Cable

Use for panel and equipment (hook-up)
Flexible
Temperature Range: -65° to 390° F
Insulation: PTFE Plastic

Our most chemical-resistant wire—the PTFE insulation protects against most chemicals, solvents, and oil. The PTFE is slippery, so it withstands some abrasion. The wire has a silver-plated finish for corrosion resistance and strength. It’s flame rated VW-1 to meet requirements for preventing the spread of flames based on a timed test with vertically suspended material. Rated MIL-W-16878/4-Type E, it meets stringent military specifications for material quality. Also known as hook-up wire.

Long-Life Continuous-Flex Wire

Metallic Tinsel

Use for automation, continuous motion
Continuous Flex
Temperature Range:
Carbon Fiber: 0° to 140° F
Metallic Tinsel: -20° to 175° F
Insulation:
Carbon Fiber: PVC Plastic
Metallic Tinsel: Polypropylene Plastic

The strands in this wire have better fatigue resistance under repeated flexing than the copper strands in standard continuous-flex wire, so it will last longer. Often used in low-current signaling in automated applications such as robotics, it withstands continuous motion without degrading data or signal transmission.

Metallic tinsel wire has thin strands of metal wrapped around a fiber core to provide better flexibility and longer service life than carbon fiber wire. Wire with a polyester plastic core has 21 strands.

High-Voltage Continuous-Flex Wire

Use for solar equipment, automation, continuous motion
Continuous Flex
Temperature Range: -85° to 325° F
Insulation: Silicone Rubber

A thick insulation protects this wire from high voltages while maintaining flexibility. The insulation also resists moisture. Often used in automated applications such as robotics, it withstands continuous motion without degrading data or signal transmission. It meets UL 94 V-0 for flame retardance.

Motor Winding Wire

Use for motors
Bend and Stay
Maximum Temperature: 390° F
Insulation: Polyamide

Also known as magnet wire, this wire is commonly used in motors, transformers, relays, and other high-speed winding applications. It meets NEMA 1000 MW-35C for material quality and -73C for use in sealed motors and material quality. It stays in the position you bend it.

Wire Wrap

Use for circuit boards
Bend and Stay
Maximum Temperature:
PVDF: 200° F
ETFE: 300° F

This wire wraps around a post terminal on a circuit board to make an electrical connection, eliminating the need for soldering. It stays in the shape you bend it for a tight wrap around the post. A silver-plated finish provides corrosion resistance and strength.

PVDF wire is also known as Kynar wire.

ETFE wire has strong resistance to harsh and high-pH chemicals, such as cleaning fluids and fuels. It’s also known as Tefzel wire.

Use a wire wrap tool (sold separately) to make a tighter connection than wrapping by hand. The tool also unwinds wire from the post.

Wire Wrap Tool

Use this tool to tightly wrap wire around a post terminal for a good connection. Insert the wire and the post into the tool; twist the tool to wind the wire around the post. To unwind, use the opposite end of the tool.

Miniature Cable

Use For: Automation, Interference Shielding, Continuous Motion
Continuous Flex
Temperature Range: -40° to 220° F
Insulation: PVC Plastic

Often used in computers, small electronics, and electronic prototyping, this cable is very flexible with small gauge wire to handle tight curves in narrow spaces. It withstands continuous motion, so it’s also commonly used around heavy vibration and in automated tasks, including robotics. A braid shield blocks interference from nearby equipment.
