CHD Series

Amphenol Industrial CHD Series Heavy Duty Connectors provides an interconnect solution that is designed for high power applications in harsh environment conditions and are available in 1pin and 2pin shunt. The right-angled receptacle is made to fit perfectly in EV inner space constraint conditions and is deigned to bring down the cable bending issues.

These heavy duty power connectors offer waterproof IP grade and salt spray performance over 500 hours that allows the CHD series to challenge tough application environments. The CHD range is completed by shunt plug and receptacle, ideal for safety applications for vehicles with Manual Service Disconnect functionality. The CHD series connectors can operate within the temperature range from -40°C to 125°C with an voltage rating of 1500V DC. These heavy duty connectors with the minimum durability of 50cycles are useful in EV chargers, power distribution unit, on-board chargers and inverters.

Frequently Asked Questions

HVIL, or High Voltage Interlock, is a safety feature of hybrid and all-electric vehicles that protects people during the assembly, repair, maintenance and use of a vehicle. The HVIL system is designed to protect anyone who may come into contact with high-voltage components throughout the lifecycle of an electric vehicle.

HVIL acts as a type of circuit breaker that sends a warning or error message to the driver if a high-voltage connection becomes loose, disconnected or damaged while the vehicle is in operation. HVIL also helps to protect the driver and occupants of a vehicle in the event of an accident. It is possible to order Amphenol Tuchel Industrial's EV connectors with or without HVIL.

Mechanical coding of connectors is a method of ensuring that connectors can only be connected to each other in a specific way. This is particularly important in applications where there are several connectors with different functions or connections in order to avoid mix-ups or incorrect connections.

The advantages of mechanical coding are manifold. It reduces the risk of misconnections, minimizes the likelihood of damage to equipment due to incorrect connections and improves overall system reliability. At Amphenol Tuchel Industrial, the EV connectors (except the MSD series) are mechanically keyed.
