SSI to Profibus IF55 gateway Connect your Lika SSI encoder to Profibus with the new IF55 gateway. IF55 gateway allows complete integration and full compliance with the Profibus-DP protocol. What is IF55? IF55 is the new gateway from Lika Electronic designed to convert any Lika SSI serial encoder into a Profibus-DP slave. The slave encoder can be configured as a Class 1, Class 2 or Class 2(+VEL) device, thus gaining enhanced functions such as scaling, extended diagnostics, velocity information. Whether your SSI device is a singleturn or multiturn rotary encoder or a linear sensor, then you can easily and reliably connect it to the fieldbus network. IF55 gateway fully complies with the Profibus-DP protocol.
A complete range IF55 gateway is also available with EtherCAT interface complying with ETG.1000 specifications and supporting CoE (CANopen over EtherCAT) and FoE (for firmware upgrade) protocols and the EtherCAT State Machine; and with CANopen interface complying with the “Device Profile for encoders” Class 2. IF55 converters use connectors and cables that meet the protocol specifications.
Why to use IF55? There are many good reasons why IF55 gateway is of a great benefit. First, in the case of a plant retrofit project, instead of being discarded an existing SSI serial interface encoder can be converted and reused in a more modern and integrated communication system. Furthermore, because of its electronics, a bus encoder has larger dimensions than a SSI model and comes from 58 mm flange design up. Today it is finally possible to install even a small encoder (Ø 36 mm!) or a minimum footprint head sensor in tight spaces not giving up the Profibus technology. In addition there is no need to make any change either in the hardware or in the software of the SSI encoder, only the converter needs few simple parameters to be programmed.
Perfect for: • singleturn and multiturn rotary encoders (for example MS36, MM36, AM36, AM58) • linear encoders (for example SMA5, SMA2) • bearingless encoders (for example SMRA)
• Fully complying with Profibus-DP • device configurable as a Class 1, Class 2 or Class 2(+VEL) slave • connectors and cables according to Profibus specifications

Smart encoders & actuators
SFP draw-wire encoders gain analogue outputs Lika Electronic is releasing new SFP series cable-pulling encoders that provide linear position feedback over distances from 300 mm / 11.8” to 2000 mm / 78.7” and analogue outputs now. Customers can now benefit through more choice in the range of cable pulling measuring solutions to select from. Lika Electronic is introducing two further output signal options in the SFP draw wire units series: 4-20mA current output and 0-10V voltage output. Analogue models come to complement the 1 to 20 kΩ potentiometer selection. Compact and robust, SFP stringpots have a rugged aluminium housing and use a reliable stainless steel draw wire mechanism. They are protected to IP64 and can operate in ambient temperatures from -25°C to +85°C (-13°F +185°F). They are available in five measuring ranges: 300 mm / 11.8”, 500 mm / 19.7”, 1000 mm / 39.4”, 1500 mm / 59” and 2000 mm / 78.7” and allow for wide cable misalignments. Aimed at linear measurement applications across all industries with medium-short displacements and limited space, they
are well matched to telescopic systems and hydraulic pistons (for instance in mobile equipment such as outriggers, stabilizing slides, telescopic cranes, booms ...), forklifts, printing machines, medical technology applications such as in examination tables, dentist’s chairs and laboratory testing devices, among others. Furthermore they are a cost-effective alternative to the linear potentiometers in applications where reliable and lowcost position verification is required. Lika Electronic offers a full line of “cable pulling” measuring solutions including stringpots (potentiometers) as well as incremental, absolute, fieldbus, Ethernet and ATEX draw-wire encoders.
