RotoLine Product Overview Rotary encoders: Precise measuring technology with defined values SIKO has united the rotary encoder and the electronic display range under the name of RotoLine. There are the following four product categories, depending on the measuring principle employed in their typical applications: ■■ ■■ ■■ ■■ Magnetic rotary encoders Optical rotary encoders Geared potentiometers Electronic Displays The comprehensive SIKO product knowhow permits a wide selection of types ranging from inexpensive rotary encoders in miniature format with simpler mechanical designs to sophisticated,...

Optical rotary encoders Optical rotary encoders use light as a medium in a similar manner to a light barrier. A code disk with a pattern of opaque and transparent segments rotates in a gap between the light source and sensor. Depending on their transmissivity, this disk either prevents or enables the passage of the light beam to the sensor on the opposite side. The sensor itself is part of the electronic evaluation system, which derives electrical pulses from the opto-electronic scanning system on the basis of which the length, angle or speed information can be calculated. Both optical incremental...

Magnetic Rotary Encoders General information and areas of application Time for a new generation – time for new standards This SIKO development with its indestructible, magnetic scanning technology is suitable for completely new mechanical engineering concepts. Both resolution and scanning reliability as well as the robustness of the compact measuring systems cover application areas which by far exceed those of optical rotary encoders. With a magnetic ring [1] mounted on a hollow or solid shaft, the rotation of machine shafts or spindles can be “transmitted” to special electronic sensors [2]....

Application areas Magnetic encoders were developed for wet or humid and heavily soiled operating conditions and where machine vibrations make precise operation difficult. For this reason magnetic encoders are predestined for a large number of different applications … ■■ These non-contacting measuring encoders almost always feel at home even if they are in contact with corrosive solutions such as saline water or in heated, oily environments. In the food, packaging, energy generation and wood processing sectors or for passenger transport and general mechanical engineering applications, optical...

Magnetic Rotary Encoders Function and application Ambient conditions Insensitive to moisture, as the scanning process does not require direct visibility. No mounting arrangements or moisture protection necessary e.g., metal saws, food production, portal-type car wash facilities, stoneworking … Unshakeable: The components employed are indestructible, the glass required in optical encoders is not necessary, all components are safely integrated. High level of reliability High level of operational reliability 2.1 2.2 e.g., presses and dies, construction vehicles, elevators, rough wood processing...
