Frequently Asked Questions
What is the Pizzato FD 638 used for?
The FD 638 is used for detecting mechanical position and movement in industrial machinery using rotating lever actuation.
What contact configuration does the FD 638 have?
The switch features a 1NO + 1NC slow action contact block, suitable for control and signalling applications.
What is the difference between slow action and snap action?
Slow action switches change state progressively with actuator movement, while snap action switches change state rapidly at a defined point. The FD 638 uses slow action switching for controlled operation.
Is the FD 638 suitable for safety applications?
Yes. It includes positive opening, making it suitable for safety circuits when correctly installed.
Does the FD 638 include an actuator?
No. The unit is supplied without an actuator, allowing selection of a compatible rotating lever accessory.
