ME-8104 Limit Switch Roller Arm Type
The ME-8104 Limit Switch Roller Arm Type is a compact industrial mechanical switch engineered to detect the presence or absence of moving mechanical parts in automated systems. It features a durable body made from a combination of reinforced plastic and metal components, with a roller-equipped arm that pivots when contacted by a machine element or cam surface. When the roller arm is deflected, internal contacts change state and send a clear signal to a control system, triggering an action such as stopping a motor or indicating an end-of-travel position. This design makes the ME-8104 suitable for repetitive use in applications where precise position detection is required.
The roller arm provides a smooth interface with moving mechanisms, allowing it to respond to directional forces over a range of motion. Its construction supports reliable electrical switching even in environments where vibration, shock, or incidental contact occur. Typically mounted with two screws, the switch integrates easily into machine frames, conveyor systems, and other mechanical structures. With isolated changeover contacts, it can handle both normally closed and normally open circuits, enabling flexible control logic depending on the specific system requirements.
Engineered for longevity and consistent performance, the ME-8104 combines a robust mechanical life with protective sealing that resists dust and splashing water. The roller arm’s geometry and return spring ensure repeatable actuation even in high-cycle environments. As a result, this switch serves as a reliable electromechanical sensor that bridges the mechanical motion of a machine to electronic control responses, making it a staple in industrial automation and safety stop systems.
