1250 Suggested Mounting Methods
Model 1250 is typically mounted by the threaded stud on either end or by the black body using a set screw.  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
