Italsensor TK20 Encoder FAQ
-
What is the Italsensor TK20?
The Italsensor TK20 is a compact incremental encoder with a 44 mm body diameter and a 6 mm stainless steel shaft. It supports up to 3600 pulses per revolution (PPR) and offers power supply options of 5 V or 11/30 V. -
Which shaft dimensions and loads can it handle?
- Shaft Diameter: 6 mm (stainless steel)
- Axial Load: 5 N
- Radial Load: 5 N
-
What are the speed capabilities?
- Up to 10,000 RPM for short cycles
- 6,000 RPM continuous
-
How much torque is required to start rotation?
- Starting Torque at 25°C: 0.005 Nm (standard), 0.006 Nm (with protection shaft)
These values represent the minimal torque needed to overcome static friction and start shaft rotation.
- Starting Torque at 25°C: 0.005 Nm (standard), 0.006 Nm (with protection shaft)
-
What is the encoder’s moment of inertia and bearing life?
- Moment of Inertia: 6 g·cm²
- Bearings Life: At least 5 × 10? revolutions
-
How heavy is the TK20 encoder?
The encoder weighs approximately 0.23 kg, making it easy to handle and integrate into compact systems. -
What electrical performance can I expect?
- Maximum Resolution: 3600 PPR
- Output Frequency: Up to 150 kHz
- Synchronous Index Output: Default on channel A (optional on B – A&B)
- Supply Current (No Load): Up to 100 mA
-
What protection features are included?
- Short Circuit Protection: Available only for LD2 and PP2 outputs
- Polarity Inversion Protection: Provided, except for the 5 V DC supply version
-
Which materials are used in its construction?
- Flange: Aluminium S11
- Housing: Aluminium S11
- Shaft: Stainless steel
-
What are the operating and storage temperature ranges?
- Operating Temperature: -10°C to +70°C
- Storage Temperature: -30°C to +80°C
Combined with a maximum relative humidity of up to 98% (non-condensing), the TK20 can function in typical industrial environments.
- How does it handle vibration and shock?
- Vibrations: 10 g at frequencies from 10 to 2,000 Hz
- Shock Resistance: 20 g for 11 ms
These ratings ensure the TK20 can withstand common mechanical stresses found in industrial applications.
- Where can I find more technical information or support?
For additional details, consult the manufacturer’s datasheet and user manual, or reach out to Italsensor’s technical support or authorized distributors. They can provide in-depth information and guidance on installation, configuration, and integration.
