Jungheinrich Forklift Relay 51139400 — 0.2kg Electromagnetic Switching Relay for Electric Forklifts
This forklift relay part number 51139400 is a Vonclay OEM electromagnetic switching relay designed for Jungheinrich ECE, ERE, ETM, and ETV series electric forklifts. At 0.2kg with a compact plastic housing, this relay controls high-current switching circuits for forklift electrical systems — including traction motor contactors, hydraulic pump solenoids, and auxiliary power circuits. The electromagnetic coil actuates silver-alloy contacts for reliable switching with minimal contact resistance, while the plastic housing provides electrical insulation and protection from dust and moisture in industrial material handling environments. Suitable for building material, manufacturing, construction, and energy/mining applications where Jungheinrich forklifts are deployed.
Installing this relay requires matching the terminal configuration and coil voltage (verify 24V or 48V based on your forklift model) to the existing relay. The 0.2kg weight and compact footprint allow direct plug-in replacement without chassis modification. After installation, verify the relay clicks audibly when energized and that the switched circuit operates correctly. OEM ordinary and OEM packaging available.
