Koganei NHB Series Swing Type Single Acting Normally Open Type

Manufacturer: KOGANEI CORPORATION

Features

To begin with, the lever is constructed from chrome molybdenum steel and incorporates quench hardened major parts, allowing it to deliver a long operating life even in demanding industrial environments. Furthermore, a magnet for a sensor switch is included as standard equipment, making integration with automated detection systems straightforward. Finally, the design supports 3-way direct mounting, which simplifies installation and provides flexible positioning options across various machine setups.
