FS6I/0B-050-59-1F IMO Fork Sensor 50mm Sen., Adj., M8 Plug Exit

Why Choose the IMO FS6I/0B-050-59-1F Fork Sensor?

The IMO FS6I/0B-050-59-1F is a high-speed photoelectric fork sensor designed for accurate detection of small objects, edges and moving materials in industrial automation systems. Its fork-shaped construction integrates the emitter and receiver into one rigid housing, maintaining precise optical alignment and simplifying installation compared with separate through-beam sensors.

This FS6 Series model provides a 50 mm fork width and 59 mm detection depth, with modulated infrared emission and detection of objects as small as 0.2 mm. Sensitivity can be adjusted directly using the integrated +/- push-buttons, while light-on or dark-on switching can also be selected by button.

Operating from 12/24 V DC, the FS6I/0B-050-59-1F provides selectable NPN/PNP digital output, a fast 10 kHz switching frequency and an M8 4-pin plug connection. Its painted aluminium and polyamide/glass construction and IP65 protection make it particularly suitable for high-speed positioning, counting, web monitoring and small-object detection on automated machinery.

High-Speed Precision Detection for Automated Machinery

Fork sensors combine an optical emitter and receiver within a single U-shaped housing, creating a precisely aligned sensing beam across the fork opening. When an object passes through this optical path, the sensor changes its output state. This arrangement eliminates the alignment work associated with separate through-beam photoelectric sensors and provides repeatable detection on fast-moving machinery.

With its 50 mm opening, 0.2 mm minimum detectable object size and 10 kHz switching frequency, the IMO FS6I/0B-050-59-1F is particularly useful for detecting small or rapidly moving parts. Adjustable sensitivity and selectable light-on/dark-on operation further simplify commissioning for different materials and machine-control requirements.

Typical Applications

• High-speed object detection and counting.
• Edge and position detection on automated machinery.
• Packaging and labelling equipment.
• Web, sheet and continuous-material monitoring.
• Small-component detection on assembly machinery.
• Conveyor product detection.
• Feed and positioning systems.
• Printing, converting and processing machinery.
• Industrial automation requiring precise through-beam detection.
