ONN-M4-50 Tri-color Custom LOGO LED Signal Tower Light 2-Year Warranty for CNC Equipment
Product Overview
The ONN-M4-50 is a purpose-built 3-tier signal tower light designed for Original Equipment Manufacturers (OEMs) and system integrators requiring reliable, no-compromise machine status indication in a compact Φ50mm footprint. With its traditional Red-Yellow-Green configuration, this unit provides intuitive visual communication of operational states—Green for running, Yellow for standby/warning, Red for fault/alarm. The optional >85dB buzzer adds audible confirmation, ensuring operator awareness in high-ambient-noise environments.
Quick Detail
Standardized Color Coding: Red (Fault/Alarm) / Yellow (Warning/Standby) / Green (Running/Normal)
Configurable Functions: Choose from 6 operating modes—Steady, Steady+Buzzer, Red Flash, Red Flash+Buzzer, All Flash, All Flash+Buzzer
Flexible Input: Available in DC12V, DC24V (with PNP/NPN support), or AC100-240V
Three Mounting Solutions: Foldable type for confined spaces, Pole & Plate for overhead visibility, L-Bracket for wall or side mounting
Durable Build: IP53-rated housing suitable for industrial workshop conditions
Simple Ordering: The ONN-M4 ordering code structure ensures accurate specification—select your mounting type, voltage, function, and connection type with ease

Competitive Advantages
OEM-Friendly: Compact 50mm diameter fits easily on space-constrained equipment without blocking operator sightlines or access panels
Streamlined Specification: The structured ordering code eliminates ambiguity—each character maps to a physical attribute, ensuring accurate fulfillment
Reduced Engineering Overhead: Universal voltage and signal compatibility mean one model supports multiple control system types
Field-Ready Installation: Screw or bracket fixation options accommodate various mounting surfaces with standard hardware
Low Power Consumption: 1.4W per color minimizes energy costs and heat generation inside enclosures
Proven Reliability: Traditional fixed-layer design with fewer moving parts translates to higher mean time between failures (MTBF)
