D-SERIES

FEATURES:

• 6mm travel
• Connection = push-in connections .75…2.5mm²
• Lamp socket BA9S (bayonet base)

Schlegel’s Dux modular D series contact blocks are color coded for easy visual reference. The contact block modules fit together and then they snap into the module holder. They have cage clamp terminals for connection. Schlegel’s D contacts can be combined for up to three sections by stacking them together. The first plane can hold up to three modules whereas the second and third planes accept two each. Modular contacts allow more “standard” customization for the customer’s requirements. Each block has finger proof terminals for safety. The D series is popular in Europe whereas the M series is more commonly used in the USA. The M series has a broader range and is more readily available from Csii’s stock on hand.
