Explosion-proof Incremental Encoder I/0Q80EXS
- Manufacturer: ELCIS Encoder
- Category: Encoder, Incremental Encoder, ATEX Explosionproof Incremental Encoder, SENSORS
The ELCIS 0Q80EXS (I/0Q80EXS) is an explosion-proof incremental encoder with a □80 square flange and a Ø10 h7 shaft, with a capacity of 1 to 10,000 pulses per revolution. It is designed for working environments with explosive atmospheres of gas «G» and dust «D», excluding firedamp mines, and is ISSeP certified according to CENELEC standards, with markings II 2 G Ex d IIC T6 Gb and D Ex tb IIIC T85°C Db IP6X (T5: T100°C) according to EN60079-0, EN60079-1 and EN60079-31, within the ISSeP07ATEX018X certificate notified by CESI02ATEX138Q. Its output electronics include NPN, PNP, push-pull, 26LS31 and 88C30 drivers, TTL, discriminator, and 1 Vpp sinusoidal output, available in unidirectional, bidirectional, and zero-channel versions. The output cable is permanently connected.

Technical Frequently Asked Questions
What is the difference between the T5 and T6 versions?
In T6 (standard) the maximum surface temperature of the housing is 85 °C and the ambient temperature is -20 to +40 °C; in T5, it's 100 °C surface and -20 to +60 °C ambient. The unbreakable disc (option Y) is only available in T6.
How do you connect the cable in an explosive atmosphere?
The encoder uses a cable rated for at least 100°C, permanently connected. The connection must be made to an Ex junction box or outside of a potentially explosive atmosphere; the cable end connector is only permitted outside of explosive atmospheres. Special conditions for safe use (symbol X): mounting screws must be of grade 8.8 or higher.
Can it be used in mines with firedamp?
No. It is built for use in all locations except firedamp mines.
