£6.03
The Pizzato MKH22D42 is a high-reliability industrial microswitch with roller lever actuator, designed for precise position detection and dependable switching in automation and safety circuits. As part of the advanced Pizzato MK series, it is engineered to deliver consistent performance and long service life in demanding industrial environments.
This model features a roller lever actuator (approximately 38 mm), ensuring smooth, low-friction actuation and reduced mechanical wear when interacting with moving components. Its reinforced technopolymer housing provides excellent durability while maintaining a compact and lightweight design for easy integration into machinery.
With a 1 NO + 1 NC contact configuration and positive opening NC contact, the MKH22D42 is suitable for safety applications requiring reliable circuit interruption. The MK series design incorporates enhanced contact reliability with double-contact technology, significantly reducing failure probability compared to conventional microswitches.
The MKH22D42 is designed for applications where both precision and safety are critical. Its positive opening mechanism ensures that contacts are physically separated when actuated, providing dependable disconnection even in fault conditions.
The MK series contact design uses redundant contact paths to reduce electrical resistance and dramatically lower failure probability, improving system reliability in industrial automation and safety circuits.
