Sangel Systemtechnik

What Sangel Systemtechnik does

Sangel Systemtechnik GmbH, now operating as HELU Connectivity Solutions Bielefeld GmbH, is a Bielefeld-based German industrial manufacturer that designs and supplies LED industrial luminaires, custom cable assemblies, and integrated system modules for use in harsh manufacturing environments. Founded in 1996 and employing 51-100 people, the company serves machine tool manufacturers (CNC milling machines, lathes), industrial production plants, drive system integrators, and OEM equipment manufacturers. Products are engineered for environments exposed to metal chips, sparks, oil, coolants, lubricants, vibration, and dust — failure modes that disqualify general-purpose LED fixtures.

The core product portfolio spans surface-mounted and recessed LED machine lights across multiple form factors (KL, SL, FLS, EBLT, ELN, ELN PRO, LR40, LR40 PRO), workplace luminaires (APLN), and combined illumination-signaling RGBW variants. Industrial-grade features include IP40 to IP67 protection ratings, ESG variants resistant to chip and spark impact, UGR19 ergonomic glare ratings, M8/M12 connector standards, and a proprietary 2-chamber DL system that delivers simultaneous internal machine illumination and external status signaling. Cable assemblies cover drive-system applications connecting servo converters and motors across manufacturer standards, with capabilities spanning LWL/fiber optic and BUS communication configurations. System modules integrate cable and lighting subassemblies to reduce procurement complexity for end customers.

The business model is hardware sales-driven across four streams: LED industrial luminaires, cable assemblies, system modules, and custom OEM solutions. Distribution is conducted through a German direct sales force, the global HELUKABEL Group sales network (since 2022), an OEM partnership program, and the HELUKABEL online product catalog. Pricing is quote-based, reflecting custom configurations and volume considerations; no public list pricing is disclosed. The company was integrated into the HELUKABEL Group in 2022 and rebranded to HELU Connectivity Solutions Bielefeld GmbH in 2024, retaining operational independence while gaining distribution scale and brand coherence under the parent umbrella.

Core offering

Sangel Systemtechnik (operating as HELU Connectivity Solutions Bielefeld GmbH) designs, manufactures, and supplies industrial LED luminaires for machine tools and workstations, custom and pre-fabricated cable assemblies for drive systems, and integrated system modules combining lighting and cable solutions for harsh industrial environments.

Product overview

Sangel Systemtechnik (now HELU Connectivity Solutions Bielefeld GmbH) offers a unified portfolio of industrial products organized into three core business areas: LED Industrial Luminaires, Cable Assemblies, and System Modules. The LED luminaires span multiple product families (KL, SL, FLS, EBLT, ELN, ELN PRO, LR40, LR40 PRO, APLN) as surface-mounted, recessed, workplace, and signal variants. RGB signal lighting variants (LR40-RGBW, SL-RGBW, ELN-RGBW, ELN-RGB, DL, APL-RGBW) extend the core luminaire lines with combined illumination and status signaling capabilities. Custom LED solutions (Sonderlösungen) address individual requirements. Cable assemblies include both pre-fabricated and custom configurations for drive systems and other industrial applications. System modules provide integrated solutions. The product portfolio is unified through shared industrial-grade quality standards, common voltage requirements (24V for most luminaires, 230V for workplace luminaires), and connector standards (M8, M12).
