Mitsubishi provide servo motors with varying levels of IP rating. In most cases an addition to the part number is required to give a high IP rating to the motor shaft. This document details the differences.
The IP rating for any item of hardware indicates the level of Ingress protection (IP). The chart below explains the differences.
The standard HF-KP/HF-MP/HC-LP/HC-RP/HC-UP servo motors are rated IP65 (excluding the
shaft). The standard HF-SP/HF-JP servo motors are rated IP67 (excluding the shaft).
IMPORTANT NOTE: to make the servo motor shaft IP67, add the letter J to the part number.
