4HS149-320

Snap action, Limit Switches, are designed to deactivate a circuit when a certain physical limit has been reached. The 4HS149-320 limit switch, in particular, is designed for use in variable speed drives as an emergency stop or overload protection, or as an external speed reference. It is also used for positioning, where the monitored position needs to be accurately determined.

The 4HS149-320 is a limit switch with a single resistor, which is used to sense the movement of a mechanical actuator, such as a lever or cam, to indicate a specific physical limit. It works on the principle of snap action and is designed to snap into contact when the resistance of the resistor is exceeded and snap out of contact when the resistance is lowered.

The 4HS149-320 has a rated current of 16A and a rated voltage of 24 VDC, allowing it to be used in a wide range of applications, including industrial and commercial automation, process control and monitoring, and safety device manufacturing. It is also suitable for applications that require high quality performance and reliability, and offers protection against mechanical shock and vibration.

The 4HS149-320 is a multi-pole switch that can be used in a variety of circuits. It is able to detect movement in different directions, and can be used to detect the motion of levers, gear trains, and camshafts. It is also capable of controlling various types of motors, which can be used to start and stop motors at specific positions, as well as providing a reference point for speed control or overload protection.

The 4HS149-320 features a low-resistance design which makes it an excellent choice for applications that require consistent, reliable performance. It is also equipped with a self-resetting mechanism, which ensures that it maintains its integrity even after multiple uses. Furthermore, the 4HS149-320 is designed with a low-cost, maintenance-free construction, making it an ideal choice for applications where cost efficiency is key.

In conclusion, the 4HS149-320 is a versatile limit switch designed for use in a variety of industrial and commercial applications. It is designed with a snap-action principle, allowing it to detect physical limits and control motors or other mechanisms in a reliable and cost effective way. Its low-cost construction, coupled with its self-resetting mechanism and reliable performance, make it an ideal choice for a variety of applications.
