Why is there no price on this page?Price, stock and lead time for this exact reference change with quantity, delivery destination and the supplier stock reviewed at that moment (US, Germany, Türkiye, Dubai), so a fixed list price would be misleading. Send the part number and quantity and you get a written quotation — first reply in 0–4 hours.

Filed under Hamamatsu, R928 is an industrial component. Additional attributes captured from the manufacturer record include type Side-on, tube diameter 28 mm, photosensitive surface shape Rectangular, photosensitive surface size 8 x 24 mm, spectral response short 185 nm, spectral response long 900 nm and spectral response peak 400 nm. The record further documents photocathode type Multialkali, window material UV glass, dynode structure Circular-cage, number of dynode stages 9, anode to cathode voltage maximum rating 1250 V and average anode current maximum rating 0.1 mA. Also captured for this reference are anode to cathode applied voltage 1000 V, cathode luminous sensitivity min 140 uA/lm, cathode luminous sensitivity typ 250 uA/lm, blue sensitivity index cs 5 58 typ 8 and red sensitivity ratio r 68 typ 0.3. In addition the manufacturer file lists luminous radiant sensitivity typ 74 mA/W, anode luminous sensitivity min 400 A/lm, anode luminous sensitivity typ 2500 A/lm, anode radiant sensitivity typ 7.4 x 10 5 A/W and gain typ 1.0 x 10 7. The same source record continues with dark current after 30 minutes typ 3 nA and dark current after 30 minutes max 50 nA. This description is assembled only from verified attributes held in manufacturer source records, which is why no marketing claim appears beside them.
