Siemens 52NL16 Legend Plate Emerg Stop Aluminum

Product Description

The SIEMENS 52NL16 is a preprinted inscribed legend plate designed for use with Siemens pushbutton units and indicator lights in industrial control applications. The plate reads EMERG. STOP in black letters on a brushed aluminum silver background, providing clear, durable identification at control stations. Built from brushed aluminum, it resists corrosion and withstands wet and oily environments. Rated for Class 51 and 52 locations, it is suitable for use in explosively hazardous, wet, and oily industrial settings such as manufacturing process control systems. The plate measures 1-7/16 inches in height and 2 inches in width and weighs 0.05 pounds.

This legend plate is used in industrial and manufacturing environments where pushbutton actuators and indicator lights require permanent, legible identification. It mounts on 3/4-inch National Pipe Straight Mechanical (NPSM) and 30 mm threaded mounting shafts located on a minimum of 2-1/2-inch centers. Mounting hardware is not included. Typical installations include motor control panels, emergency stop stations, and process control enclosures in facilities requiring NEMA or hazardous-location-rated equipment.
