Equipment and systems covered by this certificate are as follows

The Encoder Type 2REX is a small cylindrical unit (68mm in diameter with length dependent on model) containing low voltage electronic components.  The enclosure is manufactured from either aluminium, stainless steel or acid-proof stainless steel.  The enclosure comprises of cylindrical flamepaths between the End Cap & Cover Tube and Cover Tube & Housing.  The rotating shaft 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 has one threaded cable entry fitted with either a certified M20x1.5, M25x1.5, 1/2"NPT or 3/4"NPT cable gland or an M15 integral cable gland.  Both internal and external earthing is provided.


1. Minimize the risk from electrostatic discharge - clean only with a damp cloth.

2. Temperature at the cable gland or branching point could exceed 70°C or 80°C respectively - suitably rated cable must be utilized.

3. It is a condition of certification that the flamepaths have to comply with the manufacturers drawings and can only be repaired by the manufacturer.

4. The fasteners used to secure enclosure body to end shields have a minimum yield stress of 450 Mpa.

5. For models without integral cable gland use only suitably certified Ex db IIC Gb and Ex tb IIIC Db cable glands, thread adaptors and blanking elements.

6. It is a condition of certification that precautions must be taken to avoid dust from forming layers on the encoder.
