Selector switch has closed housing for IP65 protection
Ramo S series selector switches has a closed housing, offering IP65 degree of protection, and M12 terminals. Rafi says the construction means they do not need any additional housing. Like all control and indicator elements in the Ramo 22 and 30 series, they are a cost-effective construction and suitable for retrofitting, says Rafi. The switches are designed for mounting holes with diameters of 22.3 or 30.3mm, depending on the model.
Rafi also offers the Ramo Edge fixing angle which offers the option of placing the switches offset on any surfaces or on 40mm profile rails.
The Ramo S series comprises selector switches in different types with rotating angles of 40, 60 or 90 degrees. Depending on the model, the levers can be switched to up to three positions and the actuation functions momentary contact, latching or momentary contact and latching. The contact functions available are 1NC+1NO (one normally closed and one normally open), 1NO and 2NO.
The rugged selector switches are also available in illuminated versions with translucent handle marking. The simple connection with standard M12 plug terminals makes wiring unnecessary, adds Rafi, so the Ramo switches, key switches and lamps can be installed by untrained personnel if necessary. The components in the Ramo 22 series feature black front rings in synthetic material, while the Ramo 30 versions have flat stainless steel bezels.
