Controlled Switching for Industrial Safety Systems
Position switches such as the Pizzato FR656-W3K21 are used to detect movement or position within industrial machinery. The adjustable roller lever ensures smooth engagement with moving parts, reducing wear and enabling consistent actuation in high-cycle environments.
The integrated manual reset function ensures that the switch must be reset after activation, providing controlled restart capability. This makes it particularly suitable for safety circuits, emergency stop systems and machine interlocking applications where operator intervention is required before restarting machinery.
Typical Applications
- Industrial machinery position monitoring.
- Safety interlocking and guarding systems.
- Emergency stop and reset-controlled systems.
- Conveyor and material handling systems.
- Packaging and processing equipment.
- General industrial automation systems.
