Equipment and systems covered by this certificate are as follows


The Incremental Encoder type 2REXI is a small cylindrical unit (68 mm in diameter, length about 85 mm depending on middle section), containing low voltage electronic components. The four piece construction is manufactured from aluminium, stainless steel or acid-proof stainless steel. The Encoder can be marked IP 64, IP65, IP66 or IP67 depending on actual configuration. (IP X7 for max. 1 meter submersion).The middle section is designed for 1/2 “ NPT or M20 thread for the cable entry device.

Technical data

Supply voltage: 4.5 to 30 VDC / max 100 mA

Permitted range of the ambient temperature: - 40 °C to +70 °C 


The reference pressure has been measured to 5.0 bar. The encoder has been type tested with a static pressure of 4 times the measured reference pressure – i.e. 4 x 5 bar = 20 bar. In accordance with IEC 60079-1 clause 16.2, routine testing in the production to can be omitted.




The encoder is delivered without cable entry device. The user must fix a suitable Ex certified cable entry device to fulfilling IEC 60079-1 (Ex d) requirements.
