TDT40 Heavy Duty Encoder with Integrated Tachogenerator – FAQ

1. What is the TDT40?
   The TDT40 is a heavy-duty encoder with an integrated tachogenerator designed for industrial applications. It is available in various models (e.g., TDT410, TDT411, TDT420, TDT421) and provides both position feedback and speed measurement for reliable motor control and automation.

2. What are its key mechanical specifications?

   • Body Diameter (Flange): 63.5 mm (square flange design)
   • Shaft Diameter: Options of 9.52 mm or 10 mm (stainless steel)
   • Shaft Loading: 200 N axial and 200 N radial
   • Shaft Rotation Speed:
     • Up to 4,000 RPM for short cycle operation
     • 2,000 RPM continuous (with hollow shaft proof variant)
   • Starting Torque at 25°C: 0.040 Nm (standard) or 0.070 Nm (with hollow shaft proof)
   • Moment of Inertia: 50 g·cm²
   • Bearings Life: Minimum 5 × 10? revolutions
   • Weight: Approximately 0.45 kg

3. What is the encoder’s resolution and output voltage?

   • Resolution: Up to 2,700 pulses per revolution (PPR)
   • Output Voltage: 20 V per 1000 RPM
     This allows for precise position and speed measurements in demanding industrial environments.

4. Which output interfaces are supported?
   The TDT40 supports multiple interfaces including:

   • LD, LD2, PP2
   • NPN, PNP
     A synchronous index output is provided on channel A by default, with an option for an A+B configuration on demand.

5. What are the electrical specifications?

   • Output Frequency: Up to 100 kHz
   • Supply Current (No Load): Up to 150 mA
   • Protection: Short-circuit protection is provided for LD2 and PP2 outputs, and the unit is protected against inversion of polarity (except for 5 V DC systems).

6. What materials are used in its construction?

   • Flange: Constructed from thermally stabilized, anticorodal aluminum
   • Housing: Made of aluminum that is passivated and painted with an inhibiting treatment (up to 180°C)
   • Shaft: Stainless steel
     These materials ensure durability, resistance to corrosion, and robust performance in harsh environments.

7. What are the environmental specifications?

   • Operating Temperature Range: –10°C to +70°C
   • Storage Temperature Range: –30°C to +80°C
   • Relative Humidity: Up to 98% RH (non-condensing)
   • Vibration Resistance: 10 g (from 10 Hz up to 2,000 Hz)
   • Shock Resistance: 20 g for 11 ms
     These ratings guarantee reliable operation even in challenging industrial conditions.
