XB is a new size to complete the B Series
connector range
LEMO B Series connectors are now available
with a new connector size.
The XB Series can accommodate 12 or 22
electrical contacts. This connector is an
intermediate connector size between the well
known 1B and 2B Series. The market need
for a compact connector resulted in this new
high contact density product.
Features
endurance: over 5000 mating cycles
temperature range: -55°C to + 250°C
protection index: IP 50 (when mated)
360° screening for full EMC shielding
high packing density for space savings
