Two Conductors 4 Amps Electrical Connectors
Model 205
Mercotac model 205 is ideal for two-wire applications, such as thermocouples, strain gages, eddy current test devices, and wind turbine blade sensors, due to its compact size, quality signal connection, low torque and low cost. Model 205 replaces the old model 590 for Leslie speakers and Hammond organs.

- High-speed model available (205-H)

“SS” designator indicates stainless steel ball-bearing (recommended for wet or corrosive environments)
“L” designator indicates low torque / low temp.
“LS” designator indicates low temp. & stainless steel ball-bearing
“H” designator indicates high RPM
“HS” designator indicates high RPM & stainless steel ball-bearing
Model 205 is typically mounted by the knurled metal receptacle, which is press-fit into the rotating member of the machine. When mounting horizontally, mount the Mercotac so the body of the connector rotates.
