Special Stainless Steel Encoders for Food & Beverage, Chemical, Pharmaceutical, Medical, and Cosmetic Industries

Lika Electronic offers a comprehensive range of stainless steel encoders designed for food & beverage, chemical, pharmaceutical, medical, and cosmetic industries.
They are engineered to comply with the stringent requirements of these sectors and to withstand critical operating environments.

Special encoders for unique applications
Frame, flange, and shaft are made of AISI 303 stainless steel with hygienic design and smooth paint-free finish. They ensure antibacterial properties and exceptional resistance to corrosion, and avoid trapped contaminants. Rugged long-lasting bearings protected in a stainless steel housing provide enhanced encapsulation. This results in a high IP protection (up to IP67) and excellent durability under extreme conditions and temperatures (up to -40°C +100°C). Connectors and cables are expressly intended to deal with chemical exposure and frequent aggressive cleaning. Lika also manufactures a complete series of ATEX encoders.

Incremental and absolute encoder range
The range includes: I58SK optical incremental encoder; MI36K / MC36K compact magnetic encoders; AM58K high performance encoder with CANopen/Profibus interface; XC77/XAC77 series of incremental and absolute ATEX encoders certified for use in zones 1, 2, 21, 22.

I58SK is the optical incremental encoder for reliable measurements in demanding food-grade applications offering 58-mm clamp flange and 6 to 12-mm solid shaft. It is available in both square wave and sinusoidal versions and the most wide choice of output circuits: NPN, PNP, Push-Pull, Line Driver, Universal Circuit as well as 1Vpp. It boasts a max. 10,000 PPR resolution with high accuracy (2,500 PPR for sine-cosine version) and 12,000 rpm shaft rotational speed. Cable and M23 connector outputs complete the electrical configuration. Among the key benefits the extended operating temperature range (-40°C +100°C / -40°F +212°F).

When the space is constrained, miniature MI36K / MC36K is the ideal choice. This versatile and low cost encoder provides 36-mm diameter compact housing and both solid and hollow 6-mm shafts. Despite its small size, it ensures IP67-rated protection and high resistance to shocks, vibrations, and large temperature fluctuations (-20°C +85°C / -4°F +185°F). It further features an affordable yet proven magnetic scanning and delivers square wave signals through standard HTL and TTL output circuits. The resolution is up to 2,048 PPR.

AM58K is the high performance CANopen and Profibus encoder combining robustness, flexibility, interfaceability, and accuracy for the toughest food applications. It offers the highest versatility to accommodate the most diverse of mechanical and electrical requirements. It affords standard 58-mm flange diameter housing and both hollow (Ø 14, 15 mm) and solid (Ø 6, 8, 9.52, 10, 12 mm) shafts for a wide variety of mounting solutions.
The absolute encoder encompasses high-efficiency optical components and offers a resolution up to 25 bits multiturn (13 bits singleturn per 4,096 revolutions). It can be easily integrated into industrial networks as it supports CANopen and Profibus fieldbus communication interfaces for enhanced programmability and comprehensive diagnostic information including: resolution, counting direction, preset, offset, limit switches. A number of superior characteristics makes AM58K the excellent encoder for accurate positioning and long service life in food & beverage industry applications.

Lika Electronic's XC77 and XAC77 encoders are ATEX certified and comply with the Directive 2014/34/EU. They are designed to cover critical applications in hazardous food environments. They are “high-protection” category 2 compliant encoders for use in potentially explosive atmospheres. They provide an airtight, explosion-proof and flameproof enclosure made of stainless steel and high ignition protection level against both gas and dust explosive atmospheres and are intended for use in Zones 1, 2, 21, and 22 and in the temperature class T6 (T85°C). They offer an ultra-rugged stainless steel housing with oversized frame walls and smooth paint-free finish. They ensure antibacterial properties and exceptional resistance to corrosion, and avoid trapped contaminants. Furthermore they can add special surface treatments to ensure safe protection against salt water, corrosion, cleaning agents, and chemical contaminants. They encompass superior opto-electronics for accurate and dependable enduring service. They come in both incremental (XC77 series) and absolute (XAC77 series) versions and the most complete range of communication interfaces. Incremental versions provide NPN, Push-Pull, Line Driver, and Universal level output signals. Absolute versions support a variety of electrical, fieldbus and Ethernet interfaces: SSI, BiSS, bit parallel, current/voltage analogue, with integrated cam switch programmer, Profibus, CANopen, DeviceNet, Modbus RTU, Profinet, EtherNet/IP, POWERLINK, EtherCAT, Modbus TCP, etc
