Ensure essential protection in the workplace with your emergency stop system by combining it with the highly visible Harmony Lens Ring by Schneider Electric.

The Harmony Lens Ring ZBY9W2G101 is an LED illuminated 120V legend plate, which is unmarked with a yellow label. This item is often used in conjunction with an emergency switching off mushroom head push-button. Visibility is improved with the Harmony Lens Ring due to the constant LED illumination, making your emergency stop push-button easily identifiable in the workplace. When this safety mechanism is activated the ring will change to red as a clear indicator.

This legend plate is part of the Schneider Electric Harmony range of easy-to-install, practical push-button accessories. The high-quality design of this range enhances protection and accessibility in the workplace and gives you full control.

This ring is compatible with Schneider Electric XB4 and XB5 series. The yellow label on this illuminated legend plate is unmarked, making it more suitable for use in non-emergency applications as well as emergency applications. The continual illumination of the ring and activation of the red light makes certain that it is always visible to operators.

A legend plate is a component used in conjunction with push-buttons and switches to highlight the placement of the button. They can also provide clear visual indication when the mechanism is triggered. Some rings will have text or symbol engravings on them that display what happens when you press, pull, push or twist a component. This type of ring is usually used within industrial workplace settings, where tactile emergency stop processes for potentially dangerous or expensive machinery need to be obvious, quick, and easy-to-use.

A push-button is a switch mechanism that controls a function within a machine or device, such as an instant shut down.
