1HS119

Introduction

1HS119 is a type of snap action, limit switch providing uses with a dependable and affordable means of determining the limits of motion on machines. The device is designed to be mounted on a machine\'s frame or housing and is powered by two AA batteries. The 1HS119\'s working principle is based on spring-powered direct action, which is used to detect and actuate the switch when the limit of the machine\'s travel is reached. The machine\'s movement is monitored by the switch and actuated when the desired upper or lower limit is reached, resulting in an immediate electrical connection that can be used to power other components of the system.

Types of Activity

The 1HS119 provides a wide range of actuation types and can be used in applications that require either momentary or latching contact activation. Momentary contact requires the user to push the switch and the contact is made only while the switch is pressed. A latching contact requires the user to push the switch and hold until the desired contact is made and then release. This type of contact is often used when two separate actions are required in order to complete a cycle.

Applications

1HS119 snap action, limit switches are designed for use in a variety of different applications that require motion control. These applications include conveyor systems, automated production machines, robotic arms and other automated equipment. The device is also ideal for use in situations where a reliable automated means of controlling the range of travel on a machine is needed. Additionally, the device can be used to replace older mechanical limit switches, where greater accuracy and reliability is required. The device is also used for applications that require instant feedback, such as in safety circuits.

Working Principle

1HS119 snap action, limit switches use a spring-loaded direct action mechanism to detect and actuate the switch when the limit of the machine\'s travel is reached. The device comprises a small, sealed housing that contains an actuator plunger, a contact block and spring. The plunger is connected to a lever arm, which is in turn linked to a movable contact. When the machine\'s movement reaches the desired upper or lower limit, the movable contact forces the actuator plunger against the contact block and a connection is made, resulting in an electrical signal being sent. This signal can be used to control the machine or for other purpose.

The 1HS119 also offers configurable sensitivity and is available in a range of contact configurations to meet the specific requirements of the user. This allows users to customise the switch according to their application needs, such as contacts that are momentary or latching and in normally open or normally closed configurations. Furthermore, the device has a adjustable contact gap, which can be used to change the limit of motion that the switch will detect and actuate.

Conclusion

1HS119 snap action, limit switches are a dependable and cost effective means of detecting the limits of motion on machines. The device offers many features that make it ideal for use in a variety of applications and environments, such as configurable sensitivity, adjustable contact gap and a range of contact configurations. In addition, the device is simple to install and reliable in operation, making it an ideal choice for many applications.
