SMH Euro DIN connectors, also known as forklift charging connector, are robust, industrial-grade circular power/connectivity connectors used for battery, charging, and heavy-current applications. They follow DIN-style form factors with standardized mating dimensions for reliable connections in harsh environments. Ratings are 80A/160A/320A optional, wiring size vary from 25mm² to 95mm².

Applications
- Battery chargers and connections for forklifts, industrial vehicles, and material handling equipment.
- Heavy-current power distribution in industrial settings.
- Charging interfaces for e-mobility and stationary battery systems.
- Harsh-environment power coupling where secure, high-current connections are required.
Auxiliary pins on Euro DIN connectors provide control, signaling, sensing, and protective functions separate from the main power pins. Common functions include:
- Battery present / plug detect — signals that the connector is mated.
- Enable / inhibit (charge enable) — allows charger or vehicle control to enable/disable charging.
- Contactor/relay control — drives external contactors or receives contactor status.
- Pre-charge / bleed resistor control — used for pre-charging capacitors before full main-power connection.
- Voltage sense / polarity detect — low-current sense of battery or pack voltage for safety/logic.
- Temperature sensor (NTC) — monitors battery or connector temperature for thermal protection.
- Interlock / safety interlock — prevents operation unless a safety condition is met (door open, latch engaged).
- Ground/earth sense — verifies protective earth continuity.
- Communication (CAN, LIN, SMBus, UART) — data link for charger/vehicle/pack communication and diagnostics.
- Remote fault / status signals — indicate faults, charging complete, or state-of-charge.
- Keying / coding pins — mechanical/electrical keying to prevent mismating or select configurations.
- Pilot/pulse (PWM) — used in EV charging schemes to convey current limits or handshake signals.
