SUFACE MOUNTING TYPE

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.
