The 10pcs ME8169 Flexible Coil Spring Arm Limit Switch is a set of mechanical limit switches designed for CNC applications. Each unit features a flexible coil spring arm to provide smooth actuation, tolerate minor misalignment, and reduce impact on the switch mechanism. This helps improve reliability and prolong service life in demanding CNC setups. Key benefits Smooth actuation with a flexible coil spring arm reduces shock and wear, helping extend the life of the switch and the machine. Reliable limit and homeposition detection improves CNC accuracy, repeatability, and automated homing routines. Simple integration into CNC control systems and standard endstop configurations, with straightforward mounting and wiring. Compact form factor supports mounting in tight spaces without compromising performance. Durable construction designed for repeated cycling in typical CNC environments. Key attributes Functionality: mechanical limit switch for endstop and homing applications in CNC machines. Model: ME8169, supplied as a 10piece set. Arm design: Flexible coil spring arm for consistent actuation and alignment tolerance. Compatibility: suitable for integration with standard CNC control wiring and limitswitch interfaces. Size and form: compact footprint to fit tight mounting locations. Material and build: durable switch body with a resilient springarm mechanism (construction designed for repeated use). Performance and reliability Provides dependable actuation for precise stopping points in CNC axes. Designed to maintain consistent performance across multiple cycles in typical machine environments. The flexible lever helps absorb minor misalignment during installation, promoting consistent operation. Applications and use cases CNC milling machine: X, Y, or Z axis endstop and homing routines to establish accurate machine coordinates. CNC router or engraving setups: endstop detection to prevent overtravel and to repeatably locate tooling positions. Automation rigs and fixtures: reliable limit sensing in custom automation stations or tooling fixtures requiring repeatable stop positions. Notes This listing specifies a 10piece ME8169 Flexible Coil Spring Arm Limit Switch set for CNC use. No deviations from the model, quantity, or primary features are introduced.
