“Best value for mid-range rotary axes.”
- Senior Motion Control Specialist comment
22-bit encoder gives very smooth low-speed motion.
- No jitter at 1 RPM or less
Electromagnetic brake saves machine cost.
- No external brake needed for vertical loads
IP67 rating survives washdown and dust.
- Ideal for food and packaging lines
Two MS connectors make wiring fast.
- Less chance of pin damage during setup

Does the electromagnetic brake hold the load when power is off?
- Yes, the brake engages automatically when power is cut.
- Holding torque matches the motor’s rated torque (9.5 Nm).
- Use it for vertical axes or safety stops.
Can I use this motor without the 22-bit absolute encoder?
- No, the encoder is built-in and cannot be removed.
- It works with Mitsubishi absolute drives (MR-J4, MR-J5).
- You can run it in incremental mode if needed.
What is the difference between MS-type connectors and standard ones?
- MS connectors are military-spec, very rugged.
- They lock tightly and resist vibration.
- Standard connectors may loosen over time.
Which drive is best for HG-SR202BJ?
- Use MR-J4-200A or MR-J5-200A servo amplifier.
- Match drive power (2kW or higher).
- Older MR-J3-200A works with adapter cable.
What is the warranty and shipping policy?
- 12-month warranty covers defects.
- We ship within 12-24 hours after payment.
- Carriers: FedEx, UPS, DHL with full tracking.

Check your load inertia carefully.
- Medium inertia works for most rotary tables.
- For very heavy loads, choose high inertia series.
Test the brake before final assembly.
- Apply 24V DC to release brake manually.
- Brake engages when voltage drops below 2V.
Use shielded cables for encoder.
- Long runs over 20m need ferrite cores.
- Noise can cause position errors.
Mount flange on flat, rigid surface.
- 176mm bolt pattern is standard.
- Use all 4 mounting bolts for IP67 seal.
Order MS connector cables with motor.
- Generic cables may not seal properly.
- Genuine Mitsubishi cables guarantee IP67.
