Specifications#

General Specifications#

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:

The filter holder can't be removed.

Electrical Requirements#

Camera Power#

• Power supply via Power over Ethernet (PoE): Power must comply with the IEEE 802.3af specification.
• Power supply via I/O connector: The operating voltage is 12–24 VDC. As a minimum, 10.8 VDC must be supplied. To avoid damaging the camera, a maximum of 30 VDC must not be exceeded.

Opto-Coupled I/O Input Line#

• 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#

• 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#

Operation as Input#

• 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#

• 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.

Circuit Diagrams#

Cable Requirements#

Ethernet Cable#

• Use a high-quality Ethernet cable. Use of shielded Cat 5e or better cables with S/STP shielding is recommended.
• Use either a straight-through (patch) or a cross-over Ethernet cable.
• Proximity to strong magnetic fields should be avoided.
• Basler recommends using Ethernet cables from the Basler cable portfolio.

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 a twisted pair wire cable.
• 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.
• If you are supplying power to the camera via Power over Ethernet, the I/O cable will not be used to supply power. However, you can still use the cable to connect to the I/O lines.
• Basler recommends using I/O cables from the Basler cable portfolio:
  • GPIO cable, 10 m (yellow cable): For use with the GPIO lines of your camera. Also provides camera power. To avoid interferences due to crosstalk, the opto-coupled I/O lines are not connected.
  • Opto-I/O cable, 10 m (blue cable): For use with the opto-coupled I/O lines of your camera. To avoid interferences due to crosstalk, the GPIO lines are not connected. Does not provide camera power. Therefore, when using this cable, you must provide power via Power over Ethernet (PoE).
  • Opto-GPIO Y-cable, 2 x 10 m (yellow-blue cable): Allows you to use the GPIO lines and the opto-coupled I/O lines simultaneously without interferences due to crosstalk. There are two separate wires to split both I/O types. Also provides camera power.
  • Power-I/O cable, 10 m (gray cable): For use with the opto-coupled I/O lines of your camera. Unlike the opto-I/O cable (blue cable, see above), this cable allows you to provide camera power. However, because all lines are connected, crosstalk between the GPIO lines and the opto-coupled I/O lines may occur.
  • Power-I/O PLC+ cable, 10 m (gray cable): For use with the opto-coupled I/O lines of Basler cameras connected to a programmable logic controller (PLC). It adapts the signal level for zero voltage from PLC level (\<8.4 VDC) to TTL level (\<1.4 VDC).

Physical Interface#

Camera Connectors#

Ethernet Connector#

• 100/1000 Mbit/s Ethernet connection to the camera
• If power is not supplied via I/O connector: Power over Ethernet (PoE)
• 8-pin RJ-45 jack
• Recommended mating connector: 8-pin RJ-45 plug (snap-in or with locking screws)
• When using locking screws, note the horizontal orientation of the screws.

I/O Connector#

• If power is not supplied via Power over Ethernet (PoE): Power supply
• Hirose micro receptacle (part number HR10A-7R-6PB)
• Recommended mating connector: Hirose micro plug (part number HR10A-7P-6S)
