DKS 4: Incremental Encoder By adopting highly successful Mini- Disc technology, the DKS 4 is extremely robust and can resist high levels of shock and vibration. Besides has the DKS 4 a very high protection class IP 64. D ATA S H E E T Specify your individual mm dia. Encoder. Number of lines 1 to 2,48 Incremental Encoder TThe DKS 4 Incremental Encoder offers exceptional quality for its price and its range of application. Its housing is a solid zinc die-casting and is extremely compact in its design, having an external diameter of only mm. As a consequence, valuable space can be spared when installed. Options available: Interfaces Open Collector NPN, TTL/RS 422, HTL/push-pull. Face mount flange with solid shaft Ø 8 x 13 mm, Output cable. m can be used radially or axially Thanks to product flexibility there are numerous applications, for example in: machine tools textile machines wood processing machines packaging machines
