What is the maximum detection range of the SICK GL2S-P5311?

The GL2S-P5311 detects objects up to 3 m away when used with its included reflector. The minimum switching range is 0.02 m, giving you a detection window from 2 cm to 3 m.

Can I use this sensor in wet or dusty environments?

Yes, the GL2S-P5311 has IP67 protection and resists dust and water immersion, making it suitable for demanding industrial conditions including wash-down zones. Its compact sealed housing protects the optics in harsh environments.

Is the GL2S-P5311 fast enough for counting applications?

The sensor supports an 800 Hz switching frequency, which enables reliable counting and positioning tasks in automated assembly and conveying systems. This fast response time handles high-speed part tracking without missed detections.

What comes in the box with this photoelectric sensor?

The GL2S-P5311 includes a reflector and a 10 m connection cable for quick installation and setup. No additional accessories are required for basic operation.

How small is this sensor and will it fit in tight spaces?

The GL2S-P5311 has a compact form factor measuring 7.7 mm by 21.8 mm by 13.5 mm and weighs only 2 g. Its small size makes it ideal for installations where space is limited.

What light wavelength does the GL2S-P5311 use for detection?

The sensor uses a 640 nm red visible light beam, which provides easy alignment and reliable detection in industrial automation applications. The visible red light makes setup and troubleshooting straightforward.

Retro-reflective vs. direct-beam photoelectric sensors:

The SICK GL2S-P5311 is a retro-reflective sensor that bounces light off a reflector to detect objects up to 3 m away. Choose this design over direct-beam sensors when you need longer range in compact spaces, easier alignment with visible red light, or detection without line-of-sight between emitter and receiver.

For packaging lines with gaps or obstacles between sensor and target, the reflector-based design allows detection from the same side of the conveyor.
In wash-down or dusty areas, IP67 protection and the included reflector mean reliable setup without frequent recalibration.
For counting fast-moving parts, the 800 Hz switching frequency captures position changes on high-throughput production lines.
In tight cell layouts, the 7.7 mm body width fits into narrow mounting slots where bulkier sensors cannot.
When quick installation matters, the package includes both reflector and 10 m cable to reduce site preparation time.
