Before you put money into dimensional metrology machine inspection, decide what the purchase will actually do. The 500-193-30 New Mitutoyo 300mm/12" Absolute Digital Digimatic Vernier Caliper is a handheld instrument for measuring a part directly. The Yaskawa Minertia UGTMEM-06MMT51 for Mitutoyo BHN506 Coordinate Measuring Machine is a replacement servo motor for a coordinate measuring machine. They sit on opposite sides of the same workflow: one puts a measurement in your hand, the other keeps a CMM axis moving.
Quick verdict
If you need to measure a workpiece, the digital caliper is the purchase to make. If you are repairing or maintaining a Mitutoyo BHN506 coordinate measuring machine, the Yaskawa Minertia motor is the relevant part. You are not choosing between two versions of the same tool; you are choosing the item that matches your task.
Side-by-side comparison
| | 500-193-30 Digital Caliper | Yaskawa UGTMEM-06MMT51 Motor |
| Listed price | USD 89.10 | USD 1,998.00 |
| Product type | Digital caliper with 0-12 in / 300 mm range | Used CMM servo motor for Mitutoyo BHN506 |
| Condition | New | Used |
| Measurement capability | Direct part measurement with LCD and data output | Not a measuring tool; drives a CMM axis |
| Key operating detail | Absolute encoder, no origin reset needed | High-torque, low-inertia DC servo design |
Where each product wins
- For direct inspection: The Mitutoyo caliper wins because it is a complete measuring instrument with ±0.02 mm (±0.001 in) precision.
- For CMM repair: The Yaskawa Minertia motor wins because it is designed for precise positioning and smooth, vibration-free travel on a BHN506.
Product notes
#### 500-193-30 New Mitutoyo 300mm/12" Absolute Digital Digimatic Vernier Caliper
This is a new digital caliper with a 0-to-12-inch (300 mm) range and a precision of ±0.02 mm (±0.001 in). The absolute encoder means you can start measuring without resetting the origin, and the LCD helps you read values quickly. Metric-inch conversion, smooth slide operation, stainless-steel construction, and a data output port for SPC documentation round out the tool. That makes it a practical choice for inspection and quality-control work. The limitation is scope: as a handheld caliper, it measures a part directly, but it cannot drive a CMM axis or replace a motion component. At $89.10, it is the less expensive item in this comparison.
#### Yaskawa Minertia UGTMEM-06MMT51 for Mitutoyo BHN506 Coordinate Measuring Machine
This is a used Yaskawa Minertia UGTMEM-06MMT51 DC servo motor for the Mitutoyo BHN506 coordinate measuring machine. It is built as a high-torque, low-inertia axis-drive motor for rapid dynamic response and precise positioning, with smooth travel along CMM guide ways. If your BHN506 needs a replacement in its motion system, this is the kind of part to buy. The main limitation is the used condition: you are purchasing a service part with prior use, not a new component. Choose this when the job is CMM repair rather than handheld measurement.
Final choice by use case
Choose the 500-193-30 caliper when your work involves taking direct length measurements. Choose the Yaskawa Minertia motor when you need to keep a Mitutoyo BHN506 coordinate measuring machine moving. The right purchase is the one that matches the immediate task: caliper for the bench, motor for the CMM.
