SIGMATIC ML40 Micro Limit Switch

The SIGMATIC ML40 Micro Limit Switch is a compact, model ML40 limit switch from SIGMATIC designed for precise position sensing in tight spaces. In the listing, the model line is described with the designation “PRATT WHITNEY,” indicating a branding or lineage reference tied to that product family. Built for small-footprint installations, the ML40 is suited to confined enclosures and on compact actuators where reliable electrical signaling is needed to indicate that a moving part has reached its programmed limit. As a micro limit switch, it provides a discrete signal to control systems, enabling straightforward feedback for automated sequencing, interlock logic, and machine safety interlocks in aerospace and industrial equipment environments. The ML40’s form factor and interface are intended to integrate with common control circuitry and compact wiring schemes, making it a practical choice when space is at a premium and dependable limit-detection is essential for repeatable operation across production cycles.
