Omron SHL-Q55-01 Limit Switch
Omron SHL-Q55-01 is a microload limit switch with a 7.8 mm stainless-steel panel-mount plunger and SPDT contact arrangement. IP67 protection, 15 mΩ maximum contact resistance, 100 MΩ minimum insulation resistance, and ten million minimum mechanical operations are specified. Electrical durability is listed at 500,000 operations minimum, while the operating range extends from -10 to 80°C. The SHL-Q55-01 belongs to the SHL Series within the microload panel plunger switch range from Omron switching components. Its panel-mount stainless plunger is the main actuator feature.

The Omron SHL-Q55-01 Limit Switch uses a 7.8 mm stainless-steel panel-mount plunger with SPDT contacts for microload switching. The source specifies operation at 50/60 Hz, IP67 protection, 15 mΩ maximum contact resistance, and 100 MΩ minimum insulation resistance at 500 VDC. The operating temperature range is -10 to 80°C with relative humidity from 35 to 95%, and pollution degree 3 according to EN60947-5-1 is listed. Its panel-mount plunger distinguishes it mechanically from hinge- and short-lever versions in the SHL Series.
Mechanical durability is specified at ten million operations minimum, while electrical durability reaches 500,000 operations minimum. Destructive shock resistance is 1,000 m/s² and malfunction shock resistance is 300 m/s². The combination of stainless-steel panel plunger, SPDT contacts, microload designation, and IP67 protection defines this configuration without adding unsupported load values. For a related SHL model using a hinge roller lever and SPDT microload switching instead of a panel plunger, see the SHL-W2155-01 model.
