The BERNSTEIN I88-SU1Z Riwk is a compact limit switch from the I88 SU/U series, engineered for precise position detection and reliable mechanical performance in industrial automation systems. Constructed with a durable glass-reinforced plastic (GRP) housing, it offers excellent resistance to impact, corrosion, and environmental stress, ensuring long-term reliability in demanding operating conditions. The switch features an M20 connection type for secure cable entry and ease of installation. With dimensions of 62 mm in length, 22 mm in width, and 30.5 mm in depth, it provides a space-efficient solution for integration into machinery and control assemblies. Designed for extended operational endurance, the BERNSTEIN I88-SU1Z Riwk supports a mechanical life of up to 1,000,000 switching cycles, making it ideal for repetitive motion and precision limit detection. This limit switch could potentially be used across North America, Europe, Asia, and worldwide applications where compact, high-durability mechanical sensing is essential.
