# Color: light gray 

# Dimensions in mm L = (pole no. x pin spacing) + 1.5 mm2-pole female connectors – one latch only . Female connector, 721 Series, 0 ° conductor exit to connection direction Enjoy fault-free electrical installations with this female connector (item number 721-106/026-000). Ensure that the strip lengths are between 8 and 9 mm when connecting conductors to this female connector. This product features one conductor terminal and utilizes CAGE CLAMP®. Our CAGE CLAMP® connection pro vides a dependable and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping fer rules. Dimensions: (31.5 x 14.3 x 26.45) mm (width x height x depth). This female connector is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm². Tin is used for coating the contact surfaces. Page 1/9 Version 25.05.2026 Continued on next page
