SICK DFS60B-S4PK10000 Incremental Encoder - 10,000 Pulses, TTL/HTL. SICK DFS60B-S4PK10000 is a DFS60-series incremental encoder. SICK identifies this exact type as article 1036722. The exact data sheet specifies 10,000 pulses per revolution, an incremental TTL/HTL communication interface with TTL factory setting, six signal channels, output frequency up to 600 kHz and output load current up to 30 mA. It is intended for motion-feedback applications that require this exact encoder resolution and electrical interface.
