HLR-1920

The HLR-1920 was the harsh-environment member of the ALR-1920 family. It was discontinued on 1 May 2020, together with the ALR-1920, the ALR-1920-SDI and the ALR-1920-120, because the main component chip reached end of life.

The replacement is the HLT-1920 — a version of the ALT-1920 with enhanced components and conformal coating for harsher environments. It is in production now.

The four part numbers withdrawn in that notice were:

  • 4172700XX-3 — CONTROLLER, ALR-1920, RoHS
  • 4172701XX-3 — HLR-1920 CONTROLLER, HARSH ENVIRONMENT
  • 4172800XX-3 — CONTROLLER, ALR-1920-SDI, RoHS
  • 4173100XX-3 — CONTROLLER, ALR-1920-120, 120Hz, RoHS
