The Honeywell Micro Switch Model 201LS503 is a reliable and versatile electromechanical switch designed for various industrial automation applications. This micro switch is a normally open (NO) type, which means that it does not conduct electricity until a specific input is applied.
The switch's housing is made of die-cast zinc and is designed with a robust construction to withstand harsh environments. It measures 1.5 inches (38.1mm) in diameter and 0.75 inches (19mm) in height, making it a compact solution for space-constrained installations.
The 201LS503 micro switch features a long stroke lever, which allows for a large actuating force of up to 35 lb (15.9 kg). This makes it suitable for applications where a substantial force is required to operate the switch. The switch's operating force can be adjusted to accommodate various applications by using the provided adjusting screw.
The micro switch comes with a hermetically sealed switch element that ensures excellent sealing against moisture, dust, and other contaminants. It can operate in temperatures ranging from -40 F to 158 F (-40 C to 70 C), making it suitable for use in a wide range of industrial environments.
The Honeywell 201LS503 micro switch has a rated contact capacity of 1 Ampere at 250 Volts AC or DC. It also comes with a built-in LED indicator, which provides visual confirmation of the switch's status. The switch's terminals are gold-plated to ensure good conductivity and durability over time.
The micro switch is easy to install and can be mounted on a surface using the provided mounting holes. It also comes with a detachable actuator, which makes it easier to install in tight spaces. The switch's status can be monitored using the provided normally open contacts or the built-in LED indicator.
In summary, the Honeywell Micro Switch Model 201LS503 is a robust and versatile solution for various industrial automation applications. Its compact size, adjustable operating force, and excellent sealing make it suitable for use in harsh environments. Its gold-plated terminals, built-in LED indicator, and easy installation make it a reliable and convenient choice for operators and maintenance personnel.
