The L51K13ROP101 swaps the usual roller arm for a flexible rod lever, letting it trip from whichever direction an actuator happens to approach rather than needing a precise, repeatable angle. That flexibility makes it a favourite for CNC axis end-stops and 3D printer limit switches, where the exact approach angle can vary run to run.
Technical Details
Frequently Asked Questions
Is this suitable for CNC machines or 3D printers?
Yes — the flexible rod actuator is a popular choice for CNC axis end-stops and 3D printer limit switches.
Can the rod be approached from any angle?
Yes — the rod lever design allows variable-angle actuation, unlike a fixed roller arm.
Is the body durable despite the plastic rod?
Yes — the switch body itself is metal and IP65 rated; only the rod actuator is plastic.
What contact configuration does it give me?
1NO+1NC on a changeable contact block, so you can wire whichever function your circuit needs.
Industry Applications
- CNC machine axis end-stops — reliable limit detection regardless of approach angle
- 3D printer & light machine building — a common choice for hobbyist and small-scale automation projects
- Variable-angle component detection — applications where a fixed roller arm can't guarantee consistent contact
