Photoelectric Proximity Sensor GTE6-N4211 SICK 300 mm NPN IP67
Overview:
The GTE6-N4211 from SICK is a photoelectric proximity sensor (energetic diffuse type) belonging to the G6 series. It features a PinPoint red LED and offers a sensing range of up to 300 mm, NPN output, fast response time of less than 1.25 ms, and IP67 protection. With its ultra-compact design (12 × 31.5 × 21 mm) and 5-turn mechanical potentiometer for sensitivity adjustment, the sensor is well suited for packaging machines, conveyors, robotics, and high-speed automation lines.
Product Overview of the Photoelectric Proximity Sensor GTE6-N4211
The GTE6-N4211 is a photoelectric proximity sensor operating on the energetic diffuse principle. It detects objects by measuring the amount of reflected light from the PinPoint red LED (650 nm) returning to the receiver. The PinPoint technology produces a highly focused light spot (Ø 7 mm at 90 mm), enabling precise detection of small objects even in confined installation spaces.
As part of SICK’s G6 Mini series, the sensor stands out with its compact dimensions, standard M8 4-pin connector, and precise 5-turn mechanical spindle for sensitivity adjustment. It is engineered for reliable performance in harsh industrial environments, thanks to its IP67 rating and comprehensive circuit protection (A+B+D).
Key Features:
- Sensing range: up to 10–300 mm (90% remission); standard: 15–250 mm
- Output: NPN, max. output current ≤ 100 mA (≤ 50 mA when UB > 24 V)
- Supply voltage: 10–30 VDC, no-load current consumption 30 mA
- Protection rating: IP67
