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. If this wire is exposed to flames, it minimizes how much smoke and halogen it releases.

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.

Wrap Wire

Use for circuit boards
Bend and Stay
Maximum Temperature: 200° F
Insulation: PVDF Plastic

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.

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

Wrap Wire Tools

Wrap a coil tightly around a terminal post for a strong electrical connection. These compact tools won't bump into neighboring terminal posts and disrupt the rest of your circuit board, making them ideal for accessing posts that your hands can’t reach. Thread stripped wire into the tip, insert the tool over a post terminal, and twist to form a coil. Alternate between winding and unwinding by reversing the tip, just as you would a screwdriver bit.

Wrap Wire Assortments

Use for circuit boards
Bend and Stay
Maximum Temperature: 200° F
Insulation: PVDF Plastic

Keep multiple colors of wrap wire on hand to color code connections in circuit boards for easy identification. This wire winds around a post terminal to make a strong electrical connection—no soldering needed. Lightweight and flexible, it stays in the shape you bend it for a tight hold. A silver plating shields the wire from corrosion as well as wear and tear. This wire has PVDF insulation, which resists breaking down from chemicals and melting up to 200° F. Because it’s insulated with PVDF, it’s commonly known as Kynar wire.

All of these assortments come with a wire stripper to cut and strip your wire. Store and organize the wire with the included dispenser box.

For an even tighter connection than wrapping by hand, use a wrap wire tool (sold separately). Thread the wire into the tip, insert the tool over a post terminal, and twist. Alternate between winding and unwinding by reversing the tip, just as you would a screwdriver bit.

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.
