Detailed Answer
Mining remote control dust/water protection: IP67 (Lideral LD series standard, fully dustproof + 1m/30min immersion), key for humid underground environments. Some mining models IP68 (Xingjia optional, continuous immersion). Underground has many sprinkling/dust-suppression scenarios; IP67 is the baseline; check actual protection at acceptance.
| Baseline | IP67 |
| Underground | Sprinkling environment |
| Optional | IP68 |
Note:Underground remote controls with protection below IP67 cannot be used.
