EIB-Y(St)Y Bus Cable for KNX / EIB Building Automation
EIB-Y(St)Y bus cable is a screened PVC communication cable for KNX / EIB building automation applications. ETK Kablo’s 2x2x0.8 configuration combines solid copper conductors with an overall aluminium/polyester foil screen and a green PVC jacket. It forms part of our building automation cable range.
Lighting, HVAC and Shading Control
This EIB cable provides the communication connection between sensors, actuators and controllers in building automation installations. Applications include lighting control, heating and ventilation control, blinds, shading and energy monitoring in residential and commercial buildings.
Select the cable against the bus system requirements and project specification. Follow the equipment manufacturer’s instructions for cable routing, termination and permitted network layout.
EIB-Y(St)Y 2x2x0.8 Cable Size
The 2x2x0.8 designation identifies four conductors representing two pairs, with a conductor diameter of 0.8 mm. The specified construction arranges these four conductors as a star quad.
| Cable Size | Pair Count | Conductor Count | Conductor Diameter (mm) |
|---|---|---|---|
| EIB-Y(St)Y 2x2x0.8 | 2 | 4 | 0.8 |
The 0.8 value describes diameter, not a cross-section of 0.8 mm². Specify the complete product designation and required length when requesting a quotation.
Foil Screening and PVC Materials
The overall Al/PET screen surrounds the insulated conductors and includes a tinned copper drain wire. PVC insulation and a UV-resistant green PVC outer jacket complete the cable. Follow the bus system instructions for handling the screen and drain wire during installation.
The published specification lists IEC 60332-1-2 flame retardancy. PVC is not halogen-free, and this flame test does not establish FE180 or PH120 circuit integrity. For projects requiring low smoke, halogen-free materials, see the separate EIB-H(St)H bus cable.
Frequently Asked Questions
What is EIB-Y(St)Y bus cable used for?
It carries communication signals in KNX / EIB building automation applications, such as lighting, HVAC and shading control. Confirm the electrical and installation requirements of the selected system when specifying the cable.
Is EIB-Y(St)Y the same as EIB-H(St)H?
No. EIB-Y(St)Y uses PVC insulation and a PVC outer jacket. EIB-H(St)H uses halogen-free materials. Choose the product that meets the project’s material and fire performance requirements.
Can any 2x2x0.8 cable replace an EIB bus cable?
No. Matching conductor count and diameter does not establish equivalent electrical performance, insulation properties or system suitability. Compare the complete cable specification and any required approval documentation before substitution.
Can this cable be installed outdoors or underground?
The jacket specification includes UV resistance, but this alone does not establish suitability for direct burial, wet ducts or permanent water exposure. Ask ETK Kablo to confirm the appropriate construction for those conditions.
