The Leuze GS04B/P.1-80-M8.3 (Part Number: 50146167) is a high-precision optical fork photoelectric sensor from Leuze electronic's advanced Series 04B (Germany). By integrating transmitter and receiver optics directly opposite each other inside a rigid diecast zinc U-shaped frame with an 80 mm mouth width and 55 mm mouth depth, this sensor eliminates tedious optical alignment routines associated with conventional throughbeam pairs.

KEY PRODUCT FEATURES AND OPERATIONAL ADVANTAGES:
1. Wide 80 mm Mouth Width & 55 mm Depth:
The spacious 80 mm fork opening and 55 mm deep throat allow workpieces, part carriers, or rotating indexing wheels to pass freely through the active beam path without risk of mechanical collisions.
2. High Micro-Optical Precision – Detects Objects Down to Ø 0.3 mm:
Utilizing a focused 660 nm pulsed red LED light source paired with premium glass optical windows. It reliably detects small objects, thin wires, and sheet edges down to 0.3 mm in diameter, boasting an exceptional 0.02 mm (20 µm) repeatability and an ultra-narrow switching hysteresis of 100 µm.
3. Ultra-Fast 5,000 Hz (5 kHz) Switching Frequency & 0.1 ms Response:
Operating at an ultra-fast 5 kHz switching rate with a 0.1 ms (100 µs) response time, it easily handles high-throughput automated counting, sorting, and position synchronizing on high-speed production lines without missing a pulse.
4. 270° Potentiometer for Sensitivity & Light/Dark Switching:
Equipped with a 270° rotary potentiometer for fine sensitivity calibration tailored to target opacity, while also providing user-selectable Light-switching or Dark-switching operation.
5. Rugged Diecast Zinc Housing with Glass Lens Cover:
Constructed with a heavy-duty diecast zinc housing finished in RAL 9005 black powder coat, shielded with a scratch-resistant glass optical window. Rated IP67 for water and dust ingress protection, ensuring outstanding shock and vibration resistance in harsh factory environments.
6. Standard Industrial M8 3-Pin Connector (-M8.3):
Features an integrated 3-pin M8 male connector (A-coded) on the housing, eliminating cable stress damage and enabling rapid plug-and-play installation during routine maintenance.
