Why Choose the Pizzato FM525-K21 Position Switch?
The Pizzato FM525-K21 is a rugged electromechanical position switch designed for precise detection of movement and end-of-travel conditions in industrial automation systems. As part of the dependable Pizzato FM series, it offers consistent switching performance and long service life in demanding environments.
This version features a coil spring actuator with plastic tip, providing flexible and responsive actuation even where misalignment or vibration is present. Its metal housing construction ensures high resistance to mechanical stress, impact and industrial wear, making it ideal for continuous-duty applications.
Equipped with a 1 normally open (NO) and 1 normally closed (NC) snap-action contact configuration, the FM525-K21 delivers fast and reliable switching. Unlike the base version, it includes an integrated PG13.5 cable gland for 6–12 mm cables, simplifying installation and improving sealing performance. With an IP67 protection rating, it ensures reliable operation in harsh industrial environments.
