Limit Switch Heavy Industry Limit Switch
Bestact Solutions Co., Ltd.
About This Product
A limit switch with a built-in Bestact (R25) contact that has excellent environmental resistance.
■Features
It has a long track record as a position detection switch for steel equipment, chemical plant equipment, cranes in cement manufacturing equipment, and trolleys, and contributes to improving poor contact. This is a limit switch that uses Bestact (R25) for the built-in contacts, making it less susceptible to environmental influences such as dust, gas, high temperature, and high humidity, and providing excellent contact reliability. It demonstrates reliability in a wide range of applications, from signal-level microcurrent circuits to inductive load switching power circuits.
*Form □ = [ ] varies depending on the contact configuration. 2a: [200] 2b: [020] 1a1b: [110]
*The user cannot change the A contact and B contact.
*For DC circuits, connect ⊕ to odd terminal codes and ⊖ to even terminal codes.
*For crane overwinding protection, there are no particular restrictions on operating speed, but please ensure that the travel of the weight is maintained to the maximum extent possible. If the product stops short of the limit of movement, please consider measures in the electrical circuit to prevent the turned-off contact from vibrating and causing negative effects even if it is turned on again.
*For fork lever types with rollers, the minimum operating speed varies depending on the usage conditions.
*Protection structure IP56 is based on proper wiring, piping, and installation. Please note that proper waterproof and dustproof performance cannot be achieved without proper wiring, piping, and installation.
