XS3
CSM_XS3_DS_E_7_4
Small Round Water-resistive
Connectors
• Water-resistive, compact connector meets IP67 requirements.
• Conventional M8 screw-on models are available along with S8
snap-in models that connect and disconnect with one touch.
• Ideal for a wide variety of FA and OA applications.
• Connectors on both cable ends require no harness work.
• Some new M8 models with 3 or 5 poles.
• Oil-resistant Polyurethane Robot Cables added.
