Spectral Response#

Sony IMX249LQJ-C Spectral Response

The spectral response curve excludes lens characteristics, light source characteristics, and IR cut filter characteristics.

IR Cut Filter#

Color cameras are equipped with an IR cut filter. The filter is mounted in a filter holder inside the lens mount.

The IR cut filter has the following spectral characteristics:

Wavelength [nm] Transmittance
450–610 Tmin > 90 %
450–620 Tavg > 93 %
645 ± 10 T = 50 %
700–1070 Tmax < 4 %
690–1070 Tavg < 1 %

The filter holder can't be removed.

Electrical Requirements#

WARNING – Electric Shock Hazard

Unapproved power supplies may cause electric shock. Serious injury or death may occur.

  • You must use power supplies that meet the Safety Extra Low Voltage (SELV) and Limited Power Source (LPS) requirements.
  • If you use a powered hub or powered switch, they must meet the SELV and LPS requirements.
WARNING – Fire Hazard

Unapproved power supplies may cause fire and burns.

  • You must use power supplies that meet the Limited Power Source (LPS) requirements.
  • If you use a powered hub or powered switch, they must meet the LPS requirements.
NOTICE – Incorrect voltage can damage the camera.

You must supply camera and I/O power within the safe operating voltage ranges specified below.

Do not use negative voltage for an I/O line.

Camera Power#

You must supply camera power that complies with the Universal Serial Bus 3.0 specification.

The camera's nominal operating voltage is 5 VDC, effective on the camera's connector.

Opto-Coupled I/O Input Line#

Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–24 VDC Safe operating range.
0–1.4 VDC Indicates a logical 0 (with inverter disabled).
>1.4–2.2 VDC Region where the logic level transition occurs; the logical state is not defined in this region.
>2.2 VDC Indicates a logical 1 (with inverter disabled).
  • Minimum current: 5 mA
  • Current draw: 5–15 mA
  • If the camera is connected to a PLC device, Basler recommends using a cable that adjusts the voltage level of the PLC to that of the camera.

Opto-Coupled I/O Output Line#

Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
3.3–24 VDC Safe operating range.
<3.3 VDC Unreliable I/O output.
  • Leakage current: <60 µA. Actual leakage depends on operating temperature and production spread of electronic components.
  • Maximum load current: 50 mA
  • Minimum load current: Not specified. Consider the following:
    • Leakage current will have a stronger effect when load currents are low.
    • Propagation delay of the output increases as load currents decrease.
    • Higher-impedance circuits tend to be more susceptible to EMI.
    • Higher currents cause higher voltage drops in long cables.

General Purpose I/O Lines#

NOTICE: Applying incorrect electrical signals to the camera's GPIO line can severely damage the camera.

Before you connect any external circuitry to the GPIO line, use the Line Mode feature to configure the line for input or output.

Make sure to apply appropriate input or output signal voltages as specified below.

Operation as Input#
Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
0–5 VDC Safe operating range. The minimum external pull-up voltage is 3.3 VDC.
0–0.8 VDC Indicates a logical 0 (with inverter disabled).
>0.8–2.0 VDC Region where the logic level transition occurs; the logical state is not defined in this region.
>2.0 VDC Indicates a logical 1 (with inverter disabled).
  • Current draw (high-level): <100 μA
  • Sink current: Your application must be able to accept 2 mA sink current from the GPIO input line without exceeding 0.8 VDC.
Operation as Output#
Voltage Description
30 VDC Absolute maximum. This voltage must never be exceeded. Doing so may damage the camera and voids the warranty.
3.3–24 VDC Safe operating range.
<3.3 VDC Unreliable I/O output.
  • Internal pull-up resistor: ≈2 kΩ, with open collector. Many applications will have to provide an additional pull-up resistor.
  • Residual voltage ("on" state): ≈0.4 VDC at 50 mA and 25 °C (77 °F) housing temperature. Actual residual voltage depends on operating temperature, load current, and production spread of electronic components.
  • Leakage current: <60 µA. Actual leakage depends on operating temperature and production spread of electronic components.
  • Maximum load current: 50 mA
  • Minimum load current: Not specified. Consider the following:
    • Leakage current will have a stronger effect when load currents are low.
    • Propagation delay of the output increases as load currents decrease.
    • Higher-impedance circuits tend to be more susceptible to EMI.
    • Higher currents cause higher voltage drops in long cables.

For more information about the I/O lines, see the I/O Control section.

Circuit Diagrams#

Cable Requirements#

USB 3.0 Cable#

  • Use a high-quality USB 3.0 cable with a Micro-B plug.
  • To avoid EMI, cables must be shielded, as specified in the USB 3.0 standard.
  • Basler recommends using USB 3.0 cables from the Basler cable portfolio.

For more information about recommended USB 3.0 cables, see the Recommended Accessories for Basler USB 3.0 Cameras document.

I/O Cable#

  • The I/O cable must be shielded.
  • The I/O cable must have a cross-section of at least 0.14 mm² (close to AWG26).
  • Use twisted pair wire cables.
  • Maximum recommended cable length: 10 m
  • Camera-side connector: Hirose micro plug (part number HR10A-7P-6S) or equivalent
  • Proximity to strong magnetic fields should be avoided.
  • Basler recommends using I/O cables from the Basler cable portfolio:
