LM Series: Compact LED Pilot Lights for Space-Efficient Panel Design

LM Series

In industrial automation and control panel design, space efficiency and clear visual indication are equally important. Control panels are becoming more compact, yet they must still deliver reliable performance and clear status signaling.

The LM Series LED Module Pilot Lights from ESSEN are designed to meet these demands, offering a compact footprint, durable construction, and dependable illumination for modern industrial applications.

Why Choose LM Series LED Pilot Lights?

The LM Series is engineered to deliver bright, consistent illumination while occupying minimal panel space. Whether you’re designing industrial machinery, automation systems, or electrical distribution panels, these pilot lights provide multiple advantages.

Key Benefits of LM Series

  • Space-Saving Design
    Compact construction fits a standard 22.5 mm panel cut-out, making it ideal for dense panel layouts.
  • Rugged & Durable
    Shock-proof and vibration-resistant, suitable for demanding industrial environments.
  • Long Life & Energy Efficient
    Built with solid-state LED technology, consuming low current (typically 10mA to 15mA) while ensuring extended service life.
  • High Environmental Protection
    Rated IP65 at the front and IP20 at the rear, offering protection against dust and water ingress.

Wide Voltage & Multi-Voltage Support

One of the standout features of the LM Series is its ability to operate reliably under voltage fluctuations of ±20%, making it ideal for areas with unstable power supply.

Available Voltage Options

AC Supply Options

  • 24V, 48V, 110V, 220V
  • Direct connection up to 415V AC

DC Supply Options

  • 12V, 24V, 48V, 110V, 220V

Multi-Voltage Models
