These sensors, which function as two-unit through-beam systems, combine a sender and receiver in a single housing. The distance between the sender and receiver is determined by the shape of the housing and is referred to as the fork width.

Further advantages:

• large selection of fork widths and depths
• differing detection technologies, adapted for your application
• no alignment of transmitter and receiver necessary

Typical applications are:

• “transparent on transparent” label detection
• presence of small parts
• printed marks on transparent foils

WFL Laser Fork sensors

• Very high resolution
• Simple setting using 2-point Teach-in
• Rugged aluminium housing
• High switching frequency for accurate positioning
• Precise and thin laser spot

WF Optical Fork Sensors

• For applications with high switching frequencies
• User-friendly keyboard (teach-in or +/- adjustment)
• Fork widths between 2 mm and 225 mm
• Fork depths from 40 mm to 95 mm

UF3 Ultrasonic Fork Sensors

For transparent labels and more!

• Function independent of colour, transparency or printing (e.g. metallic foils, RFID labels)
• Unique on the market: the smallest metal housing
• Savings on materials (min. distance between labels = 2 mm)
• Ultrasonic technology suitable for all labels and substrates
• Most accurate positioning due to stable response time

Examples of areas of use:

• “transparent on transparent” label detection
• double-sheet detection (1 or 2 sheets)
• detection of adhesive tape
