Schneider Electric Illuminated Unmarked Legend Ring for Use with Emergency Switching Off Mushroom Head Push-Button

Enhance your workplace safety system and secure peace of mind with the highly visible, easy-to-use Harmony Lens Ring by Schneider Electric.

The Harmony Lens Ring ZBY9W2B101 is an unmarked, LED illuminated 24 V legend plate. It is made to pair perfectly with an emergency switching off mushroom head push-button. When the mushroom head push-button is pressed to initiate an emergency stop in a device or machine, the light of the illuminated Harmony Lens Ring will immediately change to bright red to visibly indicate this safety mechanism.

The unmarked ring is particularly convenient for push-button use in both emergency and non-emergency situations. It is also suitable for allowing your own specific customised labelling. The constant LED illumination of the Harmony Lens Ring and the colour change function ensure that your push-button can be viewed without fail even in darkness and conditions of poor visibility. This ring is ideal for use in commercial and industrial environments to safeguard your emergency stop system.

This legend plate is part of Schneider Electric’s high-quality Harmony range of practical push-button accessories, which are specifically designed to maximise protection in the workplace and give you optimal control.

The consistent LED illumination and flawless colour change system of this legend ring guarantees visibility of your emergency stop button at all times. The unmarked ring allows for flexibility in its application. It is compatible with Schneider Electric XB4 and XB5 series.

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.
