Doncaster SY 1.5mm 5 Core Control Cable 50m Clear | SY1.55C050

Description

This Doncaster Cables SY 1.5mm² 5 core flexible control cable comes on a 50 metre reel with a clear PVC outer sheath. Each core is Class 5 flexible copper with PVC insulation, and a galvanised steel wire braid sits under the sheath to give extra mechanical protection. The 5 cores include a green/yellow earth core.

SY is designed as an interconnecting cable for measuring, controlling and regulation in control equipment, assembly and production lines, conveyors and computer units. It is widely used across building and construction, rail and transport, automation and process control, and by electricians in fixed installations where only light mechanical stress occurs. It is best suited to dry or moist conditions indoors; outdoors it should be protected.

Frequently Asked Questions

What is SY cable used for?

SY is a steel braided flexible control cable used to connect control equipment, machinery, production lines and conveyors, and in light fixed installations.

What is the difference between SY and YY cable?

YY is a PVC insulated and sheathed flexible control cable with no braid. SY adds a galvanised steel wire braid for extra mechanical protection and screening.

Can SY cable be used outdoors?

It is best suited to dry or moist indoor conditions. If used outdoors it must be protected, for example in conduit or trunking. It is not intended for direct burial.

How tightly can I bend this cable?

A minimum bending radius of 6 x the overall diameter is commonly quoted, with some manufacturers specifying up to 10 x. Allow 10 x (about 123 mm) if you are unsure.

How much cable do I receive?
