DF-150

Product catalog summary

Overview: The DF-150 is a rotary electric encoder designed for harsh environments, utilizing Netzer Precision's proprietary technology. It offers a low profile, high resolution, and precision, withstanding extreme temperatures, shock, moisture, EMI, RFI, and magnetic fields.

Mechanical Specifications: The encoder features a hollow, floating shaft with no bearings, allowing for a low weight of 307 grams. It has a rotor inertia of 427,882 gr·mm² and dimensions of 150 mm outer diameter, 110 mm inner diameter, and 13 mm height. The material used is aluminum, with a nominal air gap of 0.6 mm.

Electrical Specifications: The encoder operates on a 5V ± 5% supply voltage, with a maximum cable length of 1,500 mm. It supports digital interfaces with analog Sine/Cosine output signals, and digital outputs are processed internally or externally.

Environmental Specifications: The DF-150 can operate in temperatures ranging from -40°C to +85°C and can be stored between -50°C and +100°C. It has a relative humidity tolerance of 98% non-condensing, shock endurance of 100 g for 11 ms, and vibration endurance of 20 g from 10 to 2000 Hz. The protection rating is IP 40.

Performance: The encoder offers an angular resolution of 18-20 bits, with a maximum tested static error of ±0.010° and extended accuracy static error of ±0.006°. It supports a maximum operational speed of 1,500 rpm and unlimited rotation measurement range.

Interface and Communication: The encoder uses Synchronous Serial Interface (SSI) and BiSS-C Interface for digital data transmission. It supports a clock frequency of 0.5 to 2.0 MHz and a position update rate of up to 30 kHz. The current consumption is 180 mA.

Cable and Connection: The encoder uses a 30 AWG twisted pair cable with a braided shield and a silicon rubber jacket. The cable is rated for temperatures from -60 to +150°C.

Additional Features: Advanced calibration and monitoring options are available through the Electric Encoder Explorer software. The encoder also offers optional Build In Test (BIT) functionality.
