Explosion-proof incremental and absolute rotary encoders
Keywords: Heidenhain, Encoders, Hazardous materials
We are informed that the Heidenhain rotary encoder programme now includes a compact range of protected units for use in hazardous locations (Plate 7). Many machines and industrial plants for the manufacture, storage, transportation and processing of flammable liquids are exposed to gases, vapours or mists that,together with oxygen in the air, can create an explosive atmosphere.
The housing of the explosion-proof encoders is just 58mm in diameter and is only slightly longer than standard encoders. Available in industrial standard mounting versions, including clamping or synchroflange, they can also be specified with hollow shaft and stator coupling.

The encoders transmit the measuring signals in TTL or HTL levels, or as 1-Vpp sinusoidal signals, and are stated to fulfil the requirements of IEC 60 079 or EN 50 014/50 018/50 019. Flameproof type of protection is with explosion class IIC. Temperature class is +115oC.
