Equipment and systems covered by this certificate are as follows

The Incremental Encoder types SCA86EX, SCH86BEX, SCH86FEX are small enclosures manufactured from stainless steel or aluminium available in a “U”-shape with removable end or in a “drop-shape” with non-removable end cap version with approximate dimensions of 70mm x 86mm x 130mm. These enclosures are populated with electronics and have a shaft passing through the main body. The shaft may be solid or hollow and with one or two ends free. The encoder designations detail the type of shaft used as follows; SCA86EX – Solid Shaft, SCH86BEX – Hollow Shaft, SCH86FEX – Hollow Shaft. The enclosures comprise of cylindrical flamepaths between the Housing & End Cap, End Cap & Cover (when “U”-shaped enclosure used). The rotating shaft also forms a cylindrical flamepath through the housing controlled by k & m factors and is held in place with 2 precision roller element bearings.  The enclosure is provided with either one or two threaded cable entries which are fitted with either a certified M20 or M25 cable gland. Alternatively the equipment can have either one or two holes in NPT size ≤ 3/4”. Both internal and external earthing is provided.

Note: Optionally the encoder can be fitted with an optical transmitter - the optical radiation output of the apparatus with respect to explosion protection is covered in this certificate based on Exception 3) to the scope of IEC 60079-28:2015.

  • Minimize the risk from electrostatic discharge - clean only with a damp cloth. 
  • Temperatures at the cable entry can reach 90 °C. Selection of cable must be appropriate for the ambient temperature range in which the product is used. 
  • No modifications must be made to the flamepaths of the enclosure without consultation to the manufacturer’s drawings. 
  • Use only fasteners with minimum yield stress of 450MPa. 
  • Use only suitably certified Ex db IIC Gb and Ex tb IIIC Db cable glands. 
  • Use only suitably certified Ex db IIC Gb and Ex tb IIIC Db blanking elements.
  • Use only suitably certified Ex db IIC Gb and Ex tb IIIC Db thread adapters.

 DETAILS OF CERTIFICATE CHANGES (for issues 1 and above):

Issue 1:

Warning label amendment and removal of reference to pcb types from ordering code.Changes to ordering code have no technical impact upon the equipment and as such no further assessment is necessary.

Issue 2:

Change of addresss from "Tranevang 1, 3450 Alleroed, Denmark" to "Huginsvej 8, DK-3400, Hilleroed, Denmark".

An additional material for the label has been added and a new PCB layout option for the terminal block PCB.

Rationalisation and improvement of Conditions of Certification.

Clarification of equipment description.

Issue 3:

Reduction of wall thickness for through shaft, addition of NPT threaded option and minor changes to drawings.

Issue 4:

Inclusion of new type of rotary seal.

Inclusion of an optical transmitter version of the encoder.

Update of IEC 60079-1 from Ed. 6 to Ed. 7.

Update of IEC 60079-31 from Ed. 1 to Ed.2.

Minor drawing changes not compromising the IECEx certification.
