MITSUBISHI OSA24R-C10 Absolute Encoder 1000000 pulses

Buy online your MITSUBISHI OSA24R-C10 Absolute Encoder reference OSA24R-C10 (MITSUBISHI A48 Encoder) from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

This MITSUBISHI absolute feedback unit from the OSA family is used on the rear of many MITSUBISHI HF Series servo motors to provide precise axis position to the CNC. It is a high-resolution absolute encoder (-A48) suited for machine-tool axes where stable closed-loop control, reliable homing and quick recovery after power cycles are required. Commonly sourced as a replacement unit for faulty feedback on CNC lathes, machining centers and automated production equipment using Mitsubishi servo packages.

The OSA24R-C10 supplies the drive with absolute position data derived from a fine scale, allowing the axis to resume without mechanical re-referencing after shutdown when the system is configured for absolute mode. With 1,000,000 pulses per revolution, it supports tight positioning and smooth low-speed motion, which is critical for contouring and threading operations. This model is typically found on HF Series motors where the physical mounting, coupling and connector match the OSA24R-C10 specification.

The unit replaces defective or noise-prone encoders installed at the motor rear, addressing symptoms such as unstable following error, drifting position, or repeated zero return alarms. When paired correctly with the motor and drive, it acts as a straightforward drop-in replacement that restores axis feedback integrity without control rework. The model code often appears as OSA24RC10 B55045, which helps confirm exact fit during maintenance planning.

Country of manufacture is Japan, consistent with Mitsubishi factory standards for durability and signal stability in industrial environments. Depending on availability, products are commonly dispatched from our Florida warehouse, with practical packaging suited for sensitive feedback devices.

Reference: OSA24R-C10

Manufacturer: MITSUBISHI

Product type: MITSUBISHI Encoder A48

Main function: Absolute position feedback for CNC servo axes on Mitsubishi motor installations

Applications: Rear-mounted on many MITSUBISHI HF Series motors used on CNC machine-tools and automated equipment

Key technical data: Absolute encoder from the MITSUBISHI OSA range, nominal resolution of 1,000,000 pulses per revolution, typical model marking OSA24RC10 B55045, rear motor mounting configuration, designed for Mitsubishi servo systems, manufactured in Japan, available for field replacement with functional warranty

In day-to-day maintenance, this model is selected when an axis begins to fault on homing, when position repeatability degrades, or after contamination or coupling wear at the motor end. Keeping a spare part on the shelf shortens machine downtime during encoder-related failures. For retrofit or rebuild work, technicians confirm the code on the existing unit and verify the mechanical interface and connector orientation before ordering.

Each unit is tested by skilled engineers on appropriate CNC test benches or simulators to verify position feedback integrity and channel reliability prior to shipment. Secure packaging helps protect the sensing head and connector during transport. A functional warranty is provided to support maintenance teams during installation checks.

This model can serve as an emergency spare for legacy Mitsubishi servo installations where the original feedback device is an obsolete part. Cnc-shopping USA supports sourcing, repair service and potential exchange service options when available, helping keep older CNC assets running without a full drive or motor replacement.

Frequently asked questions about OSA24R-C10:

How do I confirm compatibility with my Mitsubishi HF motor?
Match the code on your existing encoder with OSA24R-C10 and check the mechanical coupling, mounting pattern and connector orientation on the motor rear. If these points align, it is typically a direct field replacement.

Is this an absolute or incremental device?
It is an absolute encoder from the Mitsubishi OSA family. It provides absolute position data to the drive or controller when the system is set up for absolute mode.

What does 1,000,000 pulses per revolution indicate?
It reflects the effective resolution of the feedback scale, supporting fine position control and smooth motion, which is important for contouring and finish quality on CNC axes.

Does it come with the motor-side cable or coupling?
This listing is for the encoder unit. Most installations reuse the existing cable, bracket and coupling if they are in good condition. Inspect these items during replacement and renew if wear is present.

Can this replace a different OSA model?
Replacement should follow the exact model code printed on the original unit. Using a different OSA variant may lead to interface or mounting mismatches unless confirmed by the machine builder or drive documentation.
