Achieve precise machine homing and reliable axis limit detection with this mechanical endstop sensor. Engineered for CNC machines and 3D printers, this robust limit switch provides a consistent, physical contact signal to your controller, ensuring repeatable accuracy and protecting your machine from travel overruns. Features and Benefits
- Durable Metal Lever Arm - Provides long-lasting mechanical actuation and resists wear from repeated use in demanding workshop environments.
- SPDT (Single Pole Double Throw) Configuration - Offers both normally open (NO) and normally closed (NC) contact options for flexible integration with various control boards and safety circuits.
- Compact and Standardized Mounting - Features common mounting hole patterns and a small form factor for easy installation on new builds or as a direct replacement for existing endstops.
- High-Precision Micro Switch - Delivers a crisp, definitive electrical signal upon actuation for immediate and reliable controller response, eliminating false triggers.
- Screw Terminal Connections - Enable secure, tool-free wiring that withstands vibration, ensuring a stable electrical connection over time. Applications
- 3D Printer Axis Limiting - Install on X, Y, or Z axes to define print volume boundaries and establish a consistent home position for every print job.
- CNC Router/Mill Travel Limits - Safeguard against gantry or spindle crashes by defining the maximum physical travel of each machine axis.
- DIY Automation and Robotics - Integrate as a positional sensor in custom projects to detect the presence or limit of movement for arms, slides, or gates.
- Machine Tool Retrofit - Upgrade older equipment or replace worn endstops with a reliable, standardized component for improved safety and operation. Note: Check your controller board specifications for NO/NC compatibility before installation to ensure proper configuration.
