31LN1
Storage indicator cathode-ray tube
Description
31LN1 is an Storage indicator cathode-ray tube for conversion of electrical signals into an image retained until the selected erasure mode removes it.
Full descriptionCollapse description
31LN1 purpose
The tube converts electrical signals into a visible image on a phosphor screen. Its operating mode is set by the heater, acceleration, focusing and beam-deflection circuits of the host equipment.
Construction and operation
The writing beam is focused electrostatically and deflected magnetically. The storage screen and erasure circuit distinguish this tube from an ordinary indicator CRT. Its glass envelope is baseless and includes external leads that must be matched to the host equipment.
Main characteristics
The key parameters are listed in Technical Details below. Selection requires comparison of the complete designation, screen, electrical ratings, lead arrangement, dimensions and mass of the exact execution.
Selection, installation and testing
A visually similar tube is not an approved substitute without a direct documentary reference. Inspect the screen, neck, leads and sealed joints before installation. Protect the glass envelope from impact and point loading; perform high-voltage tests under the host-equipment procedure.
Ordering 31LN1
Minimum order: 5 pieces. State the designation, quantity and required documents. Other executions are listed under Cathode-Ray Tubes; the general operating principle is described in the reference article.
