ETD/ETA/ETS SERIES
TRI-STATE TYPE
PATENT NO.: 5065276(U.S.A.)
47618
4856189(U.S.A.)

 

FEATURES

  • With three state (1, open, 0) setting function, especially suitable for encoding/decoding of tri-state encoder/decoder integrated circuit to obtain more security codes than traditional two-state (1,0) operation. For instance, 9 bits with tri-state gets 19,683 (39) codes, while two-state has 512 (29) codes, gains 38 times more codes with a ECE tri-state DIP Switch.
  • Bottom sealed to ensure free of flux immersion during wave soldering.
  • All plastics are UL 94V-0 grade fire retardant.
  • Gold plated contact to ensure low contact resistance and tin plated terminals to prevent contamination during soldering.
  • Twin contacts designed to ensure stable contact.
  • Ideal for coding tele-communication, transceiving, remote control and burglar alarm systems which use integrated circuits with tri-state coding systems.
