Banner lists cutoff distances of 10, 15, 30, and 45 mm; the right model also depends on its output type, connection, electrical requirements, and mounting arrangement.
What the Q2F is designed to do
The Q2F is a flat-pack photoelectric sensor intended for restricted spaces around rails, brackets, fixtures, and embedded machine installations. Banner describes it as detecting objects at short distances while ignoring backgrounds, including in scenarios involving submillimeter targets and dark or low-reflectivity surfaces. These are manufacturer-described capabilities, not independent test results. Banner’s Q2F overview provides the product description.
In fixed-field sensing, the sensor is intended to detect a target within a set cutoff while ignoring objects beyond it. Banner’s sensing-mode comparison says this mode requires no configuration. The cutoff distance is one selection criterion, not a guarantee that every target will be detected in every installation; verify the exact model documentation and the target and background conditions for your machine. Banner’s sensing-mode comparison describes the operating mode.
Q2F cutoff distances and common specifications
Banner lists four Q2F cutoff distances: 10, 15, 30, and 45 mm. Choose a cutoff appropriate to the intended sensing position and the geometry around the target; then confirm the remaining model details rather than choosing by distance alone.
| Specification | Banner-listed Q2F detail |
|---|---|
| Cutoff distances | 10, 15, 30, and 45 mm |
| Emitter | Visible red LED |
| Response time | 850 μs |
| Enclosure rating | IP65 |
| Fixed-field configuration | Banner says no configuration is required |
The mode and general Q2F specifications above come from Banner’s comparison document; cutoff options are also listed in the product overview. Check the current documentation for the precise part number before designing around a specification.
Where a low-profile Q2F may help
Restricted or embedded mounting positions
The flat-pack form can be useful when space is limited near rails, brackets, fixtures, or inside a machine. The relevant question is whether the sensor can be mounted in the available envelope while aiming at the sensing area and connecting the selected cable or connector.
PCB inspection example
Banner describes fitting a Q2F beneath a printed circuit board in an automated optical inspection machine. In its example, the sensor indicates whether the area in front of an inspection camera is clear before the next board moves into position; the inspection may be looking for issues such as missing components or soldering errors. This is Banner’s application example, not an independently validated performance claim. See Banner’s Q2 family page.
How to choose the exact Q2F model
- Set the required cutoff. Select among the listed 10, 15, 30, or 45 mm options based on the target position and surrounding geometry. Confirm the chosen part’s exact cutoff specification.
- Match output type and logic. Check whether the machine input requires PNP or NPN, and verify the part’s light-operate specification. Do not assume the output from one Q2F model applies to another.
- Choose the connection. Confirm whether the installation needs an M8 or M12 connection, a particular pigtail length, or flying leads. Include cable routing and access in the physical fit check.
- Verify electrical and environmental fit. Check the exact model’s supply range, operating conditions, and enclosure requirements against the machine installation.
- Check mounting details and included hardware. Banner says the Q2F includes a mounting bracket with M2 and M3 mounting options. Confirm the bracket and hole arrangement for the exact part ordered.
Official model listings illustrate why the full part number matters: Q2FAP3FF30-Q5 is a 30 mm PNP model listed for 10–30 V DC with a 150 mm four-pin M12 pigtail quick-disconnect and 850 μs response time; Q2FAN3FF30-Q5 is an NPN example; and Q2FAN2FF10-2M demonstrates a flying-lead configuration. These examples show variation, not a complete specification for all Q2F models.
