GSAA42B

GSA42B is a type of snap action limit switch. It is used for monitoring position and movement of objects such as machine components, objects in a conveyor line, and for activating mechanisms in various automated systems.

Application Field

GSA42B snap action limit switch is designed for use across a variety of industries and applications. It is suitable for applications involving hazardous location and safety-critical applications. It is designed for reliable operation and long life performance in a variety of environments. Examples of some of the applications it is suitable for include:

• Factory automation - assembly lines, sorting, conveyors, bottling, etc.
• Machinery control - safety interlocks, machine tool-cuts, power automation, etc.
• Materials handling - lifting equipment, hoists, cranes, conveyors, etc.
• Industrial process control - ventilation fans, pumps, valves, motors, etc.
• Parking systems - car doors, security systems, card readers, etc.

Working Principle

GSA42B limit switch works by detecting the presence or absence of a moving object or machine component. The limit switch is typically mechanically actuated, using an internal lever mechanism, when an object comes into contact with it. It then opens or closes an electrical circuit depending on the type of switch being used. For example, a normally open switch, when triggered, closes the circuit. Conversely, a normally closed switch will open the circuit when activated.

GSA42B limit switches are designed for reliable operation and long-term performance, making them widely used in hazardous locations and safety-critical applications. GSA42B limit switches feature reliable and repeatable actuation, with the ability to detect very small movements. Additionally, a variety of accessories, such as protective guards, spacers, and covers, are available to further enhance the switch’s performance.
