The Roller Lever Switch employs a system which allows selection of the of only one side (left or right) or both sides without use of any tools. Operating Position Mark (arrow) Bearings The copper-alloy bearings ensure long life expectancy. Receptacle The plug-in type receptacle provides adequate space for wiring. Conduit Opening *, * G / threads featuring high sealing property are used. (Refer to Limit Switch Connectors for details on SC connectors). A terminal box with /-NPT threads is also available on request. Sealed Gasket The employed full-cover method prevents the gasket from direct exposure to oil or water spray. Roller The roller actuator is made of hardened stainless steel and excels in resistance to wear. Lever With the Roller Lever Switch, the lever can be installed anywhere in a 0 range (80 if the lever is reversed and attached to the shaft). Oil Seal Improved sealing property is ensured with a double-seal construction (a oil seal plus an X-ring seal). Switch Box Boasts long life expectancy (0 million mechanical s or more with the -pole Double-break Switches and 0 million mechanical s or more with the DPDT Double-break Switches). Ground Terminal Screw A ground terminal is provided to enhance safety. Switch Box Screw A Phillips screw is used to secure the switch housing for ease of use, and features a measure to prevent the screw from coming off. Easy-maintenance Block Mounting Block makes it possible to easily assemble or disassemble the head, switch body, and receptacle of the by tightening or loosening the attached screws. Actuator Switch box Head Receptacle Note:. NBR is used in rubber components. Fluoro-rubber sealed types use fluoro-rubber.. For Roller Levers, there is some lever play in the free position (about mm), but this is due to the structure of the head and does not interfere with performance. *. A Receptacle and Terminal Box with /-NPT threads are also available for the North America market. *. The thread indication has been changed from PF/ to G/ accompanying the JIS B 00 revision. This changes applies only to the indication; thread sizes and pitches have not been affected. 7
