The NG1VB-510-M is an adjustable limit switch with a plastic roller lever arm, fitted with a snap-action contact block providing 1 NC and 1 NO contact. The roller lever arm length is adjustable between 28 and 78 mm, allowing the actuating point to be set to suit the application, and operation is possible at approach speeds from 0.5 to 120 m/min. The housing is anodized die-cast alloy with an IP67 degree of protection, and the switch connects via a single M20 x 1.5 cable entry, suiting use on machinery and panels where position sensing of moving parts is required in demanding environments.
