Quick Answers
A:Which X-ray tubes is it compatible with?
The NK-RM202 works with X-ray tubes up to 150 kV, with a standard 60 mm focal-spot-to-mounting-surface distance. Send us your tube model and we’ll confirm compatibility within 24 hours.
B:Manual or electric — which should I choose?
If you adjust the field size occasionally and want a lower-cost, low-maintenance option, the manual NK-RM202 is ideal. For frequent, remote adjustments, ask us about our electric collimator models.
C:Do you support OEM / customization?
Yes. As the factory, we support OEM branding and can adapt connectors and mounting to your equipment. Contact us with your requirements.
D:What’s the lead time?
Standard models are in stock and typically ship within 3–7 working days after payment. Worldwide delivery available.
