Sunlight-Resistant Through-Beam Sensor for Robotics Project

[TodoHumanoid]

Hello everyone,

I am writing to you for some help on the choice of a suitable through-beam sensor for our latest robotics project. In the past, we always used the Autonics BJ15M-TDT-C sensor. However, we face a challenge this time as it seems the robot will be working in direct sunlight. Thereby the IR photoelectric sensor might be not an appropriate sensing method. I'm on the lookout for a robust replacement that can handle these specific requirements:I'm on the lookout for a robust replacement that can handle these specific requirements:

Compact Size: The device should be as miniature as Autonics sensor measurements, about 20 mm x 35 mm.

Durability: They must be able to withstand impacts and vibrations up to a maximum of 50G for short periods of time.

Output Type: Consequently, I propose NPN output with the highest voltage of 5V.

Power Requirements: Vars input can handle DC of 12V or less and even up to 24V is possible for DC.

Sunlight Compatibility: Would be highly suitable for direct sunlight.

Response Time: 0.93-10-9.

Detection Type: Aiming at the beam of light is preferred, but any retro-reflective trail that can be found in the area will do also. The limitation of the range doesn’t have to be more than 1m.

Object Detection: Needs to be able to spot a translucent orange cylinder item.

I also look forward if you provide any remarks or ideas. This is for our FRC team, and we are really looking forward to getting the best possible sensor for the job. Thanks in advance!

I share the same issues with the sensors that are bright holes in front of cameras. undefined

Banner Engineering Q20 Series:

Size: A very tiny size, only 20mm x 32mm big.

Durability: Among others, built to resist high levels of vibration and shock.

Output: This component has NPN output below 5V.

Power: It can work with a DC input of up to 24V.

Sunlight Performance: Designed specifically for outdoor use, it is effective in all kinds of daylight.

Response Time: Responses are fast and mostly under 1ms.

Type: It is distributed through the beam.

Detection: Is suited for objects like the foamy ones, the opaque type.

Omron E3Z-T61 Series:

Size: Modestly larger but this would still mean it is small.

Durability: Designed to be able to withstand heavy loads and vibrations in industrial areas.

Output: NPN output compatible.

Power: Work with DC input from 12 to 24V.

Sunlight Performance: It has built-in function to keep the device away from interference that carries over from ambient light.

Response Time: Less than 1 millisecond response time.

Type: Among the various options, through-beam and retro-reflective options are also provided.

Detection: Available for opaque objects mostly.

Either of these options should be able to do your jobs well and work well in direct sunlight. Here is to hoping this helps and good luck with the FRC project of yours!
