Model 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.

Typical Body Mount Dimensions

MODEL HOLE DIAMETER () * DEPTH
1250, et al 1.248"    (31.70) .80"    (20.0)

Typical Threaded Contact Mount

1250 (inch)  3/8 - 16 UNC .70"   (17.8)
1250-M (metric)  M10 X 1.5 .70"   (17.8)
*Inch (mm) Tolerance     +.001" (+.025)
     -.000" (-.000)





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
