Power Supply: Options include 5 V DC and 5 to 30 V DC with reverse polarity protection.
Output Types: NPN, NPN open collector, push-pull, line driver, and RS-422.
Max Output Frequency: 15 kHz.
Accuracy: ±0.35° typical, ±0.60° max.
Operating Temperature: -20°C to +100°C (-4°F to +212°F).
Enclosure Rating: IP 54 when properly installed.

Mechanical Specifications:

Bore Diameter: 6, 6.35, 8, or 10 mm.
Shock Resistance: 50 G, 11 ms.
Vibration Resistance: 20 G, 10 to 2000 Hz.
Material: Magnet holder made of EN-AW 2011 aluminum, cover made of PA66 glass fiber reinforced.
Weight: Approximately 100 g (3.5 oz).

Connections: The encoder features cable outputs with specific color coding for different channels and power connections.

Ordering Code: The document includes a detailed ordering code system to specify the desired configuration of the encoder, including options for cover, resolution, zero pulse, power supply, electronic interface, bore diameter, enclosure rating, and output type.

Compliance: The encoder complies with electromagnetic compatibility standards IEC 61000-6-2 and IEC 61000-6-4.
