SATO afstandssensor LT408 R07327030

Precision label registration starts with a sensor that reacts in under 1 millisecond. The SATO LT408 transmissive gap sensor uses an infrared LED emitter/receiver pair to detect gaps, black marks, notches, and holes across a wide range of label media. It is the exact replacement part for SATO industrial printers including CL4NX, CL6NX, S84-EX, S86-EX, and M84Pro series, ensuring every print lands exactly where it should.

Overview

Built for SATO's LT408 series, this sensor assembly integrates directly into the printer's media path. It outputs a clean digital signal when the infrared beam is interrupted or passes through a gap, giving the printer's controller an immediate reference point for label start position. The sensor operates on a typical 5V DC supply and connects via SATO's proprietary multi-pin connector, with an integrated cable length of approximately 150–300 mm for easy routing inside the chassis.

What stands out

• Ultra-fast response time under 1 ms for high-speed printing
• Supports gap, black mark, notch, and hole detection modes
• Compatible with multiple SATO industrial printer families
• Durable ABS housing withstands daily production environments
• Simple screw-mount installation for quick replacement
