LX-101-Z: Panasonic NPN Color Mark Sensor

LX-101-Z from Panasonic is a high-speed Color Mark Sensor built for registration-mark detection on packaging, printing, and labeling lines. It combines fast teaching with stable 10 ± 3 mm sensing to cut misprints and reduce waste on Indian shop floors—precisely why engineers standardize on LX-101-Z.

The Panasonic NPN Color Mark Sensor LX-101-Z pairs a precise optics stack with tri-color emitters (RGB LEDs at 640/525/470 nm) to read subtle contrast and hue changes at a fixed distance. At the heart is an NPN open-collector output on a plug-in connector for quick panel swaps, while the 4-digit red LED display and dual teaching modes (2-level or full-auto in Mark mode; 1-level in Color mode) speed up commissioning. You get a tight spot size of 1 × 5 mm at 10 mm, ultra-fast response—45 µs (Mark) and 150 µs (Color)—and selectable Light-ON/Dark-ON or Consistent-ON/Inconsistent-ON logic to match PLC programs without rewiring. Designed for reliability, it runs on 12–24 V DC with low power consumption (~750 mW), integrates short-circuit protection, and carries IP67 (IEC) sealing with wide ambient ratings (−10 to +55 °C, 35–85% RH) for wash-down and humid lines. Mechanical resilience is proven with vibration up to 20 G and shock ~50 G; electrical robustness includes 1 kV AC withstand. For long runs, cabling can be extended to 100 m with ≥0.3 mm² conductors, and the built-in variable timers (1–500 ms ON/OFF delay) suppress PLC input chatter at high speeds. In short, these specs make the LX-101-Z a trustworthy, line-rate-ready sensor for real-world industrial duty.

In application, start by mounting the LX-101-Z ~10 mm from the web so the 1 × 5 mm beam fully covers the registration mark; use background/mark teaching to lock the target color and reduce false triggers from glossy film. On fast form-fill-seal and labelers, the 45 µs Mark-mode response supports tight print registration, while the 1–500 ms delay timer filters micro-jitter from vibrating guides. For cartons and pouches with varying inks, switch to Color mode (consistent/inconsistent logic) to validate correct artwork before sealing. Keep ambient light under ~3,000 lx at the receiver, route the 12–24 V DC line away from high-noise drives, and take advantage of IP67 sealing for wipe-downs—practical habits that maximize uptime with the Panasonic NPN Color Mark Sensor.

LX-101-Z buyers often search LX-101-Z price LX-101-Z datasheet LX-101-Z manual. As a quick guide: pricing varies by quantity and cable/connector option; the datasheet details optics, timing charts, and wiring for the NPN output; the manual covers teaching sequences, timer setup, and troubleshooting for ink/film combinations. If you see the variant spelled “LX 101 Z,” it refers to the same Panasonic NPN Color Mark Sensor. For procurement and engineering review, reference the exact model string LX-101-Z.
