GL6L-N1212

The SICK GL6L-N1212 is a compact, versatile through-beam photoelectric sensor. This sensor system consists of two separate units: a transmitter (emitter) and a receiver. It offers highly reliable detection by generating a continuous beam of light between the two units; an object is detected when it interrupts this beam.

Key Features & Specifications:

Feature Specification
Sensor Type Through-Beam Photoelectric Sensor
Sensing Principle The transmitter emits a focused beam of light which is captured by the receiver. Detection occurs when an object obstructs the beam.
Light Source Modulated Infrared Light (IR) - Invisible to the human eye, providing high immunity to ambient light interference.
Sensing Range Up to 2.5 meters (The effective operating distance between the transmitter and receiver).
Aperture Angle Very narrow, providing a precise beam for accurate detection.
Output Type PNP Normally Open (NO) (Sourcing output).
Output Function Dark-On. The output switches ON when the beam is interrupted (when the receiver does not detect the light).
Housing Material Plastic (PBT) - Offers good chemical resistance.
Housing Size Compact, rectangular form factor.
Connection Type Pre-wired Cable, 2 m (PUR jacket). The specific variant (e.g., straight) should be confirmed from the exact order code.
Supply Voltage 10...30 V DC
Current Consumption Transmitter: Max. 40 mA / Receiver: Max. 35 mA
Switching Frequency 2.5 kHz (2,500 switching operations per second) - Very fast response.
LED Indicators Transmitter: Green LED indicates power.
Receiver: Green LED for power, Red LED for signal strength (aids in alignment) and switching status.
Protection Rating IP67 - Dust-tight and protected against temporary immersion in water.
Alignment Aid Red LED on the receiver provides visual feedback for precise alignment during setup.
