Why Choose the Pizzato MKH12F40 Safety Microswitch?
The Pizzato MKH12F40 is a high-performance industrial microswitch with rear roller lever actuator, designed for precise position detection and dependable switching in automation systems. As part of the advanced Pizzato MK series, it delivers exceptional durability, electrical reliability and consistent performance in demanding industrial environments.
This model features a back direct action roller lever (approximately 48 mm), allowing actuation from the rear with extended reach. This configuration is ideal for machinery requiring early engagement, indirect actuation or flexible installation where front access is limited.
With a 1 NO + 1 NC snap-action contact configuration, the MKH12F40 ensures fast and reliable switching. Its reinforced technopolymer housing provides resistance to impact and wear, while optional terminal covers enable protection up to IP65, making it suitable for harsh industrial environments.
