Lighting systems - Electro-mechanical interfaces - Part 2-1: Four-pin extra-low-voltage twist-lock interface Type ZB18

IEC 63494 2-1:2026 specifies the interchangeability requirements of an electro-mechanical interface with four-pin extra-low-voltage (ELV) twist-lock interface – type ZB18 for use in lighting systems.

This twist-lock interface has four electrical contacts that are suitable for ELV voltages. Two connections are intended for supply power and two are intended for digital communication.

This document specifies interchangeability related requirements for:

mechanical,
electrical,
ambient conditions,
positional orientation,
communication protocol, and
pin assignments for the interface.

Specific requirements for the devices that can utilize the interface such as sensors, communication modules, cameras, etc., are not within the scope of this document.

This document does not specify the following aspects:

the lighting technology,
the illumination performance,
electromagnetic compatibility (EMC).
