- FEATURES
- With three states (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 gets 512 (29) codes, gains 38
times in former!
- Bottom sealed standard to ensure free of flux immersion during wave soldering.
- All materials are UL 94V-0 grade fire retardant plastics.
- Gold plated contact to ensure low contact resistance and tin plated terminal to prevent
contamination during soldering.
- Twin contact designed to ensure stable contact.
- Ideal for coding of tele-communication, transceiving, remote control and burglar alarm
systems which use integrated circuits with tri-state coding system.
