£5.62
The Pizzato MKH12F31 is a compact and high-reliability industrial microswitch with rear short lever and roller actuator, designed for precise position detection and dependable switching in automation systems. As part of the advanced Pizzato MK series, it offers excellent durability and consistent performance in demanding industrial environments.
This variant features a back direct action short lever (approximately 26 mm) with standard roller, allowing actuation from the rear of the switch. This configuration is ideal for applications where indirect or reverse-side actuation is required, providing flexibility in machine design and installation.
With a 1 NO + 1 NC snap-action contact configuration, the MKH12F31 ensures fast and reliable switching. Its technopolymer housing offers high resistance to impact and wear, while optional terminal covers allow sealing up to IP65, making it suitable for harsh industrial environments.
The MKH12F31 is designed for applications where actuation occurs from behind or via mechanical linkage. The rear lever with roller provides reliable triggering even in confined or complex machine assemblies, improving design flexibility and installation options.
Its snap-action switching mechanism ensures rapid electrical response with minimal contact bounce, enhancing reliability and reducing maintenance requirements in industrial automation systems.
