M12 connectorsyog standardized ncig connectors dav siv nyob rau hauv industrial automation thiab sensor daim ntaub ntawv. Cov pins ntawm M12 connector yog txawv los ntawm ntau yam:
1. Pin Numbering
A-coded (feem ntau): Feem ntau muaj 4 lossis 5 tus pins, tab sis tuaj yeem mus txog 8. Pin numbering feem ntau yog clockwise thaum saib los ntawm pem hauv ntej ntawm tus txiv neej connector.
B-coded: Siv rau Profibus thiab lwm yam kev siv tshwj xeeb.
D-coded: Feem ntau 4 tus pins, siv rau kev sib txuas Ethernet.
X-coded: 8 pins, siv rau kev sib txuas cov ntaub ntawv ceev (txog 10 Gbps).
2. Xim Coding
- Txhua tus pin tej zaum yuav muaj cov xim tshwj xeeb uas cuam tshuam nrog nws, tshwj xeeb tshaj yog nyob rau hauv pre-wired cables, los pab txheeb xyuas lub hom phiaj ntawm txhua lub xaim. Cov xim tuaj yeem sib txawv nyob ntawm cov chaw tsim khoom thiab cov qauv ua raws.
3. Keying
- M12 connectors siv sib txawv keying (mechanical coding) los tiv thaiv mismating. Lub keying yog txiav txim los ntawm coding ntawm connector (A, B, C, D, P, S, T, X).
4. Pin Layout
- Lub cev kev npaj ntawm tus pins yog lwm qhov sib txawv. Piv txwv li:
M12 A-coded 4-pin connectors muaj pins teem rau hauv ib lub voj voog.
M12 D-coded 4-pin connectors muaj pins teem rau hauv ib lub xwmfab.
5. Kev sau npe thiab kos npe
Ntau lub connectors muaj cov cim ntawm lub tsev lossis lub connector nws tus kheej qhia tus lej pin.
6. Daim ntawv thov-Specific Pinouts
Cov pinouts kuj tseem yuav txawv raws li daim ntawv thov. Piv txwv li:
Cov ntawv thov fais fab tuaj yeem muaj cov haujlwm tshwj xeeb rau lub zog thiab hauv av.
Cov ntawv thov cov ntaub ntawv (xws li Ethernet) muaj cov haujlwm pin rau kev xa cov ntaub ntawv thiab txais tos.
Piv txwv ntawm Pin Assignments (A-Coded 4-Pin Connector):
Pin 1: Xim av (Power/Signal)
Pin 2: Dawb (Signal / Transmit)
Pin 3: Blue (hauv av)
Pin 4: Dub (Signal/Receive)

Hauv daim duab no:
Pin 1 (xim av): Hwj chim lossis teeb liab
Pin 2 (Dawb): Teeb liab lossis xa tawm
Pin 3 (Blue): Hauv av
Pin 4 (Dub): Teeb liab lossis txais
Kev nkag siab txog qhov sib txawv no ua kom muaj kev sib raug zoo thiab txhim khu kev qha hauv ntau daim ntawv thov kev lag luam.
