InteliSENS® SLRmini-i4 W

Speed & Length Measurement

The SLRmini-i4 W has a wide-angle lens for the measuring less reflective and curved surface products in “roll to roll” or “cut to length” processes, such as wire, cable, hose, tube and pipe.

Non-contact, high accuracy measurement is ideal for drive control and for when length measurement is critical for product quality.
The SLRmini-i4 W is bi-directional, with ‘zero speed’ capability and automatic direction detection.
The SLmini-i4 W connects easily to all standard control systems.

Very small and easy to install
No moving parts, increased reliability and MTBF
No slip, no wear, no marking of the product being measured
Full integration with PLC, or use standalone.
Industry 4.0 data communications
Pulse outputs that simulate and replace an encoder
Permanent calibration, minimal maintenance
Measures forward and reverse line movement, and zero speed (no motion).
