The LED components behind reliable equipment

Standard flat SMD LEDs for PLC indicators, control cabinet status lights, and safety annunciators. These applications require high operating temperature ratings, long service life, and consistent color appearance across panels manufactured months apart — all addressed by single-factory CMH sourcing.

850nm and 940nm infrared emitters for proximity detection, object sensing, and remote control receivers. High radiant intensity with narrow emission cone for directional sensing applications. 940nm wavelength is optimized for silicon photodetector response and minimizes interference from ambient lighting.

Ultra-low-profile side-emitting LEDs are placed along the edge of a membrane overlay or industrial keyboard to create even, diffused backlighting across the entire surface. Consistent wavelength binning ensures uniform color across large panels and between replacement units.

Side-emitting LEDs with a narrow 30° beam angle couple efficiently into light pipe apertures, routing light from a PCB-mounted source to a panel indicator up to 50mm away. This approach eliminates the need for surface-mounted indicators on the front panel and simplifies sealing for IP-rated enclosures.

Two independent LED dies in a single package enable multi-status signalling without doubling the board footprint. Common configurations include OK/Fault (green/red) and Active/Standby (green/amber). Ideal for power supplies, network switches, and alarm annunciator panels where space is constrained.

Dome-lens LEDs deliver high-visibility status indication on equipment front panels and rack-mount chassis. Wide viewing angles ensure readability across the room, and consistent binning means uniform appearance across multi-unit installations — critical for telecom, test, and industrial racks.

Ultra-compact 0402 and 0603 flat SMD LEDs for on-board status monitoring. These components are mounted directly on PCBs to provide visual feedback for power, fault, link, and activity states. Low-profile design minimizes board real estate while delivering reliable visibility through chassis apertures or light pipes.
