The Leuze A7-V1-DS-O-T Tower Light Optical Element (Order Code: 50135458) is a high-performance optical signaling module belonging to the premier A7 Series (Advanced Series) developed by Leuze electronic (Germany). Designed to provide distinct, highly visible machine status alerts from considerable distances across the factory floor, this modular element ensures that equipment operators and maintenance crews can immediately interpret production stages and react promptly to process fluctuations.

The optical element incorporates high-efficiency industrial LEDs that emit a bright orange (amber) light in continuous illumination mode (Continuous Light). Featuring a carefully designed internal refraction lens pattern, it produces a uniform 360° radiation angle without creating harsh glare, ensuring superior optical contrast even under intense factory overhead lighting. In standardized industrial color coding, steady orange illumination represents an early warning or preparatory condition—alerting personnel to cycle pauses, impending material runouts, or scheduled inspection interventions.

Engineered with a standardized Ø70 mm cylindrical diameter and a length of 50 mm, the housing is manufactured from impact-resistant, UV-stabilized engineering thermoplastic capable of resisting industrial cutting oils and chemical splashes. The element utilizes Leuze's ergonomic Bayonet fastening system, allowing operators to stack, rearrange, or replace calotte lenses in seconds with a simple twist without requiring hand tools. The internal electrical contact pins are keyed to safeguard against accidental pin inversion (Protected against accidental interchanges), and the module is actuated via standard 24 V DC (PNP / VCC logic) with an energy-efficient current draw of maximum 50 mA.

A standout reliability feature is the exceptional LED service life exceeding 100,000 operating hours (over 11 years of continuous 24/7 service without bulb replacements), virtually eliminating maintenance interventions and unwanted machine downtime. Certified to IP66 environmental ingress protection according to EN 60529, the element is completely dust-tight and impervious to powerful water jets, ensuring dependable performance within ambient temperatures from -10°C to +60°C. Fully compliant with international CE and CSA directives, the Leuze A7-V1-DS-O-T is the premier visual signaling standard for CNC machining centers, plastic injection presses, automated robotics, food packaging machinery, and automated intralogistics conveyor systems.
