The possible options/performances of EEx 841 are limited by
the certificate (SP04ATEX3619X). The possible
options/performances are:
1. Line counts other than mentioned in the specification on
request. Only glass discs can be manufactured.
2. Temperature class: (Ta = ambient temperature)
T6, -20°C < Ta < +40°C, 4200rpm max
T5, -20°C < Ta < +60°C, 4200rpm max
T5, -20°C < Ta < +70°C, 1500rpm max
T5 means that the surface temperature of the encoder
never exceeds 100°C (running). Most Ex-classified motors
are working in class T3 (200°) which means that an
encoder with T5 can be used together with these motors.
3. Electronics with screw terminal connection and 3 or 6
channel output, all short-circuit protected via PTC
4. ADS, Advanced Diagnostic System is available on
request.
