Pinouts (M12 & Terminal)
This page provides complete pinout details for the OV10i smart camera's connectors, including the 17-pin M12 Power & I/O interface and the M12 X-coded Ethernet port.
M12 A-Coded 17-Pin: Power & I/O Connector
The OV10i uses a male M12 17-pin connector for power, digital I/O, and reset functionality.
Pin Layout
| Pin | Signal Name | Function |
|---|---|---|
| 5, 6 | Power GND | 0V return path |
| 7 | DIO GND | Ground return for digital I/O |
| 8 | Digital Input 0 | NPN logic input |
| 9 | Digital Input 1 | NPN logic input |
| 10 | Digital Output 0 | NPN open collector |
| 11 | Digital Output 1 | NPN open collector |
| 12 | RS232 RX (optional) | Not used in standard configuration |
| 13, 14 | Power VIN (+24 VDC) | Primary power supply input |
| 15 | Reset Input | Pull low to reboot |
| 16 | Trigger Input | NPN trigger or dry contact |
| Others | Reserved / NC | Not electrically connected |
Pins 5, 6, 13, and 14 are required for powering the device.
M12 X-Coded Ethernet Connector
This 8-pin connector supports Gigabit Ethernet.
| Pin | Signal | Function |
|---|---|---|
| 1 | TD+ | Transmit Data (+) |
| 2 | RD+ | Receive Data (+) |
| 3 | TD- | Transmit Data (-) |
| 4 | RD- | Receive Data (-) |
| 5-8 | Bi-Directional | Gigabit pairs |
Use an X-coded M12 Ethernet cable for connectivity.
Wire Color Reference (M12 17-Pin)
| Pin | Signal | Wire Color | Function |
|---|---|---|---|
| 5 | GND | Pink (PK) | Power Ground |
| 6 | GND | Yellow (YE) | Power Ground |
| 7 | DIO GND | Black (BK) | Digital I/O Ground |
| 8 | DI0 | Gray (GY) | Digital Input 0 - NPN Active Low |
| 9 | DI1 | Red (RD) | Digital Input 1 - NPN Active Low |
| 10 | DO0 | Violet (VT) | Digital Output 0 - NPN Sinking |
| 11 | DO1 | Orange (OG) | Digital Output 1 - NPN Sinking |
| 13 | Vin+ | Light Blue (LTBU) | Power Input Positive (19-24V) |
| 14 | Vin+ | Black/White (BKWH) | Power Input Positive (19-24V) |
| 15 | Reset | Brown/White (BNWH) | System Reset - NPN Active Low |
| 16 | Trigger | Red/White (RDWH) | Trigger Input - NPN Active Low |
| 1,2,3,4,12,17 | Reserved | - | Not connected |
Digital I/O Electrical Summary
| Type | Logic | Trigger Method | Current Limit |
|---|---|---|---|
| Trigger Input | NPN-compatible | Pull to GND | - |
| Digital Inputs | NPN-compatible | Pull to GND | - |
| Digital Outputs | NPN Open Collector | Pulls to GND when active | 100 mA per line |
Digital outputs (DO0 / DO1) are NPN open-collector, sinking only. They pull the line to GND when active and cannot source +24 V. An external pull-up or load to +24 V must be provided for proper operation.
Always tie DIO GND (Pin 7) to your system or PLC ground.
Power Wiring
Dual Power Input Design:
- Pin 13 & 14: Both connected to Vin+ (19-24V positive)
- Pin 5 & 6: Both connected to GND (power ground)
- Dual connections provide redundancy and ensure consistent voltage across components
If there is insufficient power, modify the wiring to ensure that the 24V power supply is connected to both Vin+ ports (pins 13 & 14), rather than only connecting it to a single terminal.
Best Practices
- Use M12 screw-lock cables rated for industrial use
- Verify wiring polarity before powering up
- Add ferrules or strain reliefs in control panels
- Never hot-swap the M12 Power/I/O connector
