Extending the range of ATEX incremental encoders

Lika Electronic introduces a complete series of ATEX category 3 incremental encoders: they are intended for use in potentially explosive zones 2/22 and offer the broadest range of connection options.

Lika Electronic widens the ATEX product range and introduces the new series of IX58 - CX58 category 3 incremental encoders. Category 3 comprises the products designed to meet the requirements of the new 2014/34/EU European Directive (also referred to as “new ATEX Directive”) and suitable for a safe use and a normal level of protection in areas in which explosive atmospheres caused by mixture of gases and vapours (zone 2) or dust (zone 22) are unlikely to occur and if they do occur do so for a short period of time. They comply with the constructional safety requirements of the temperature class T5 (T100°C).

IX58 – CX58 ATEX encoders complement the XC77 series of ATEX incremental encoders that are category 2 compliant and intended for use in Zones 1, 2, 21, 22 and in the temperature class T6 (T85°C).

From a mechanical point of view they feature a compact 58 mm diameter industrial enclosure with IP65 protection rate; furthermore they are designed in a complete range of mechanical models: you can choose either from the Ø 6, 8, 9.52, 10 and 12 mm (0.24”, 0.31”, 3/8”, 0.39”, 0.47”) solid shaft versions with servo or clamp flange mounting; or from the Ø 14 and 15 mm (0.55”, 0.59”) blind hollow shaft versions.

IX58 - CX58 offer increased electrical protection and safety systems according to ATEX yet they keep maximum versatility and adaptability. They are available in both digital and analogue interfaces: single-channel or quadrature digital signals are provided via NPN, PNP, Push-Pull, Line Driver and Universal output circuits with resolutions up to 10000 PPR; the analogue interface is the 1Vpp type with resolutions from 500 to 2500 PPR. The permissible counting frequency can be up to 300 kHz. The ATEX encoders have axial and radial cable output with length on request. An overcurrent protection is installed in all interfaces and complemented by the reverse polarity protection and the short-circuit protection at output in specific interfaces.

IX58 - CX58 encoders guarantee an increased safety level in all industrial environments where an occasional risk of a gas and dust explosive mixture may occur.
