Petercem Sensors

What Petercem Sensors does

Petercem Sensors is a France-based designer and manufacturer of current and voltage measurement sensors engineered for severe operating environments. The company produces a portfolio of current sensors (CS, ES, HRS-I, HRS-T, NCS, NCS-T, RFCS series) and voltage sensors/detectors (VS, VD, VenuS PVE/PVS series), covering measurement ranges of 20A to 40,000A and up to 5,000V. Its products incorporate proprietary 100% resined construction and galvanic isolation to resist shocks, vibration, electromagnetic disturbances, and temperature extremes from -55°C to +105°C. An in-house testing laboratory performs electrical, mechanical, magnetic, and environmental qualification testing. The company holds ISO 9001, IRIS, UL, and cULus certifications and complies with EN 50155 and EN 45545 railway standards.

Petercem serves three primary verticals — Energy (wind power, solar, storage, UPS, power quality), Mobility (railway infrastructure, rolling stock, marine, industrial vehicles), and Industry (variable speed drives, rectifiers, special machines). Named customers include ALSTOM and SNCF in rail and VESTAS in wind energy, with products qualified into specific OEM platforms such as SNCF NAT trains and VESTAS V164 offshore turbines. The company operates from its headquarters in Saint-Bonnet-de-Mure and a logistics platform in Veyrins Thuellin, France, and is a member of the MAFELEC TEAM group alongside sister companies spanning switches, signaling, and electronic systems across Europe and Asia.

The business model is enterprise field sales of quote-based, project-specific hardware with optional custom adaptation; pricing is not publicly listed and a minimum invoice of 200 EUR HT applies. Distribution is direct via in-house commercial and technical teams, supplemented by trade-show participation and cross-marketing under the MAFELEC TEAM umbrella. The company is privately held under MAFELEC TEAM ownership (since 2021), having previously been part of ABB (acquired 2017), and is led by President Gilles Heinrich.
