How to Re-attach an Industrial Sensor Cover

When removing the top of the sensor housing to replace batteries, re-seat a seal, or disconnect the power switch, carefully unscrew the screws.

Once you finish with maintenance, use a torque wrench or screwdriver with the following specifications for securing the screws to the top of the housing. Tighten screws using a Phillips head bit set to 0.9 Nm / 7.9 in-lbs. Tighten the screws in a star pattern to not put undue pressure on one side of the seal, or pop the seal out one side.

  • Do not overtighten the housing screws.
