FAQs
The FER1D2821SW uses a thread-coupled bayonet mating interface within the Souriau VGE1-FER1 family. Install by aligning the plug to the receptacle, engage with a quarter-turn to lock, and secure with the appropriate connector accessory if needed. Ensure the seal is intact for IP67 protection and crimp all #16 contacts per the defined procedure to maintain current rating and reliability.
Key specs include 37 contacts of Crimp #16, IP67 protection, aluminium shell size 28, and a 55.3 mm main dimension with 500 mating cycles. The connector is a straight plug with thread coupling and operates from -40 °C to 100 °C, making it suitable for harsh industrial environments.
Yes. It is fire and smoke certified, UL94 V0 rated, RoHS and REACH compliant, and IP67 rated, which supports use in regulated industries and environments with exposure to dust, moisture, and flame exposure.
Applications include automation and robotics harnesses, power distribution panels, and equipment where space is constrained yet reliable connectivity and environmental protection are essential. The 37-contact configuration supports dense interconnects in control cabinets and field devices.
With up to 500 mating cycles, the connector supports high-reliability deployment. For maintenance, inspect seals and contacts at regular intervals, replace any worn components, and use the compatible Souriau VGE1-FER1 accessories to preserve IP67 integrity during reassembly.
