SICK Retroreflective Photoelectric Sensor, Rectangular Sensor

Sick Series G6 Photoelectric Sensor, IP67, 100mA Maximum Current - GL6-P1111

This photoelectric sensor is a Compact retro‑reflective detector designed for industrial automation tasks. It emits a visible red pin‑point beam to detect objects via a reflector and operates from low‑voltage DC supply, offering sealed protection for use in harsh environments. The rectangular, panel‑mount form with two indicator LEDs provides clear status information for integration into control systems.

Features & Benefits

• 10V to 30V DC supply enables broad low‑voltage integration
  PNP output supports sourcing logic and easy interfacing
  Response time 650μs allows high‑speed detection
  IP67 sealing protects against dust and temporary immersion
  Pin‑point 650nm LED produces a small, precise light spot
  3‑wire 3‑pin cable simplifies wiring with standard connections

Applications

• Suitable for object presence detection on conveyor lines
  Ideal for part counting in Compact assembly stations
  used with reflectors for long‑range material gating
  Can be used for sensor feedback in pick‑and‑place systems
  Suitable for light barrier tasks in packaging machinery

What kind of beam characteristics does it use for detection?

It employs a visible red pin‑point LED with a Wavelength of 650nm and an approximate spot diameter of 8mm at 350mm to concentrate the sensing area.

How is the output protected against electrical faults?

The output provides reverse‑polarity protection on supply lines, input/output protection, and overcurrent/short‑circuit protection for resilient operation.

What environmental temperatures can it endure during operation?

It operates between −25°C and +55°C and can be stored between −40°C and +70°C, with temperature stability following adjustment of ±10°C.

What are the mechanical connection and construction details?

The enclosure is moulded from ABS/PC with a PMMA front screen, supplied with a fixed 2m PVC cable, and mounts using M3 fastenings.

What switching behaviours and frequencies does it support?

It provides selectable light/dark switching with a switching frequency up to 1000Hz and a maximum output current of 100mA (limited to 50mA at supply voltages above 24V).
