Spring Plungers（Initial Load (Range)：50.01~100）

A spring plunger is a mechanical device consisting of a pin or plunger enclosed within a housing, with a spring providing force to extend or retract the plunger. When not acted upon, the spring pushes the plunger outward from the housing. Applying external force compresses the spring, allowing the plunger to retract. Once the force is removed, the spring pushes the plunger back out. Some spring plungers have locking mechanisms for added stability. They are widely used in manufacturing for precise positioning, retaining objects in place, aligning components, and providing adjustable force. They can also serve as safety devices by giving feedback or triggering switches. In essence, spring plungers offer a simple yet effective solution for controlling motion and force in various applications. To select a Misumi spring plunger, consult the product specifications for factors such as size, material, spring force, and any additional features required for your specific application needs. Then, use MISUMI's online catalog or contact direct our MISUMI for assistance.
