Product Introduction

The cleanroom door status indicator groups green, amber and red LED lenses in a compact stainless wall plate. The interlock controller or access system drives each circuit to communicate door availability, transition or restricted status before a user touches the opening. The wide diffused lenses remain visible from the corridor, while the sealed front and removable rear terminal simplify integration beside single doors and multi-door airlocks.

Key Features

Three physically separated LED colors provide an immediate state indication without relying on text.

Diffused lenses distribute light across a wide viewing angle in bright corridors.

The brushed stainless front plate tolerates regular wipe-down around controlled entrances.

Independent low-voltage inputs allow the display logic to be assigned by the interlock controller.

Customer Product Concerns

Users need to understand the door sequence before attempting entry, especially when another airlock leaf is already active.

Personnel pull a locked interlock door because its state is not obvious from the corridor.Large green, amber and red lenses display the controller state before contact with the handle.

Small indicator LEDs disappear under bright cleanroom lighting.Diffused high-area lenses remain visible across a wider approach angle.

One combined lamp cannot distinguish a transition from a restricted state.Three independent circuits support separate available, waiting and locked signals.

Typical Applications
