What are name plate legends and why are they important?
Name plate legends provide fixed identification for push buttons, selector switches, pilot devices and emergency stops in electrical control panels. They are often supplied as part of a legend plate kit for signalling devices, ensuring that each function is clearly marked with durable text or symbols. Clear legend plate labels improve operational accuracy, while indicator legend plates highlight system states such as stop, fault or run. Correct use of legend plates for pilot devices and signalling reduces errors and supports safety in machinery and process environments.
What is an operator legend plate, and where is it used?
An operator legend plate is a label that surrounds an operator switch, helping to identify the function of that switch within a control system. These plates are commonly used on automation panels; emergency stop stations and reset circuits. They can be combined with pilot device legend plates, legend plate inserts, or custom legend plates for operator switches to provide consistent identification across a panel. Common sizes such as the 22mm legend plates are designed to match industry standard push buttons and selector switches for control and signalling devices.
How do indicator legend plates support control and signalling devices?
Indicator legend plates are used to label pilot lights, signal lamps, and status indicators in industrial control systems. They indicate various conditions such as faults, emergency stops, standby modes, or operational states. A scale legend plate is often applied to rotary dials or adjustment controls to show different ranges, while name plates provide identification for the overall device. These plates improve efficiency by enabling quick recognition of system conditions, even in complex environments.
What are pilot device legend plates used for in industrial systems?
Pilot device legend plates are essential for labelling push buttons, selector switches, pilot lights and operator controls. An emergency stop nameplate or emergency stop legend plate ensures that emergency shutdown points are clearly visible. For specific requirements, custom legend plates for operator switches provide tailored marking solutions, while legend plate accessories and legend plate inserts support a range of panel configurations.
What is the difference between plastic vs aluminium legend plates?
The distinction between plastic and aluminium legend plates lies in their durability, cost, and environmental suitability. Plastic legend plates are lightweight and cost effective, making them suitable for standard electrical panels and operator stations. In contrast, aluminium plates provide greater strength, abrasion resistance, and long-lasting clarity, making them more suitable for demanding environments. Both types are available as legend plate kits for signalling devices, including scale legend plates, emergency stop legend plates, and emergency stop nameplates. This variety ensures that control systems can be configured with the correct legend plate material for the required industrial application.
