Model 205
Two Conductors,
4 Amps
 

High-speed model available (205-H)
Low-torque/low-temp. models available (205-L)
Available with stainless steel ball bearing (205-SS)
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.

 Model 205 Suggested Mounting Methods
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.

Installation Notes:

  • the up arrow should not point below horizontal
  • do not solder to or bend connector tabs
  • avoid lateral forces and mechanical loads (overly stiff or tight wires)
  • do not rigid mount both ends of connector
  • limit mounting eccentricity (runout / wobble) to .005″ (.13mm)
  • provide overload protection within the circuit
  • avoid vibration and bumping motions
