3 × 4 12keys braille keypad kubantu batabona B667

Ibisobanuro bigufi:

Iyi klawi ifite ikimenyetso cya braille muri buri buto kubantu bakeneye umuntu udasanzwe,

Urufunguzo n'imbere byubatswe kuva chrome isize zinc alloy (Zamak) ifite imbaraga nyinshi zo guhangana n'ingaruka no kwangiza kandi nayo ifunzwe kuri IP67.

Twitwaje ibikoresho bigezweho byo gukora neza, ibikoresho byihuta byihuta, ibikoresho byo guteramo plastike neza, umurongo uteranya byikora hamwe nibikoresho byo kugenzura / kugerageza.

Ibicuruzwa

Kumenyekanisha ibicuruzwa

Iyi klawi hamwe no kurimbuka nkana, kwangiza-kwangiza, kurwanya ruswa, kutangiza ikirere cyane cyane mubihe by’ikirere gikabije, amazi y’amazi / umwanda, ibikorwa bikorerwa ahantu habi.
Mwandikisho yabugenewe yihariye yujuje ibyifuzo byinshi bijyanye nigishushanyo, imikorere, kuramba hamwe nurwego rwo hejuru rwo kurinda.

Ibiranga

1.Key ikadiri ikoresha ubuziranenge bwa zinc.
2. Utubuto twakozwe muburyo bwiza bwa zinc alloy, hamwe nubushobozi bukomeye bwo kurwanya irimbuka.
3. Hamwe na silicone isanzwe ikora reberi -kurwanya uruhu, kurwanya ruswa, kurwanya gusaza.
4. Kabiri PCB ukoresheje urutoki rwa zahabu, kurwanya okiside.
5.Ibara rya buto: Chrome nziza cyangwa isahani ya chrome.
6.Komeza ibara ry'ibara ukurikije ibyo umukiriya asabwa.
7.Ubundi buryo busanzwe.

Gusaba

Nibikorwa cyane cyane sisitemu yo kugenzura, terefone yinganda, imashini igurisha, sisitemu yumutekano nibindi bigo rusange.
