Question
What should be checked for beam positioning feedthrough?
Detailed Technical Explanation
Beam positioning feedthrough requests need clarification before quotation: confirm whether the buyer means a cable feedthrough, vacuum feedthrough, optical beam alignment part or a machine positioning sensor, then compare mounting, sealing, wiring and environment.
For real industrial purchasing, the safest method is to compare the old part, the electrical input, the mechanical fit and the application before treating two models as interchangeable.
