Leybold 20099046 Preamplifier / Ion Collector & Faraday Cup Collector

The Leybold Phoenix series and several other mainstream helium mass-spectrometer leak detectors share a highly common signal-collection architecture inside the mass-spec cell — the Faraday cup collector plate dimensions, the preamplifier interface pins, and the mounting geometry largely follow the same standard. That is why Leybold OEM part 20099046 works across models and brands. For a maintenance team, it means you no longer need a dedicated spare for every machine: a single part covers multiple detectors of different brands on your floor.

Fitment confirmation

The assembly is an integrated 'preamplifier board + Faraday cup ion collector' unit. Terminals use standard OEM pins for a firm, rattle-free connection; the collector plate matches the Leybold Phoenix mass-spec cell and the multi-brand models listed above. If your model is not in the table, send us the equipment model and a photo of the old part and we will confirm compatibility before you order.
