Standard HG-SR series motors do not include an integrated oil seal. For setups mounted to oil-bath gearboxes or subjected to splashing oils, opt for the HG-SR102J variant to prevent winding degradation.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #2b6cb0; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1.5rem;\"\u003eThe high-frequency signals from the 22-bit serial encoder are sensitive to electrostatic discharge and EMI.
