16mm x 5-core flexible cable, like SY cable, is typically used in industrial settings for control and instrumentation applications, such as on production and assembly lines, or for fixed and mobile equipment like air conditioning systems. Its flexible design and protective galvanised steel wire braid make it suitable for indoor, dry, ambient, or wet environments where it needs to navigate tight spaces or be moved. However, its use is restricted to indoor applications unless a more rugged, UV-resistant cable, such as H07RN-F cable, is specified for outdoor or harsher environments.
