Omron SHL-Q55 Limit Switch
Omron SHL-Q55 is a general-load limit switch with a panel-mount plunger using a 7.8 mm diameter stainless-steel plunger. It has an SPDT contact form, operates at 50/60 Hz, and carries IP67 protection. Maximum contact resistance is 15 mΩ, while mechanical durability is ten million operations minimum. The SHL-Q55 Stainless Panel Plunger belongs to the SHL Series within the Omron Panel Plunger Switch Range from Omron Control Products. Insulation resistance is 100 MΩ minimum at 500 VDC. Its panel-mount format, stainless-steel plunger, SPDT switching, general-load classification, and IP67 protection define this SHL version.

The Omron SHL-Q55 Limit Switch uses a panel-mount plunger with a 7.8 mm diameter stainless-steel plunger and an SPDT contact form. It is classified for general load and operates at 50/60 Hz. Maximum contact resistance is 15 mΩ, while insulation resistance is 100 MΩ minimum at 500 VDC. Electrical durability is specified at 500,000 operations minimum and mechanical durability at ten million operations minimum. IP67 protection is listed. The operating temperature range is -10 to 80°C, with relative humidity from 35 to 95%. Pollution degree 3 is specified according to EN60947-5-1.
Destructive shock resistance is 1,000 m/s² maximum and malfunction shock resistance is 300 m/s² maximum. The supplied row does not provide a separate current or voltage load rating, operation mechanism, connection type, operating speed, or operation frequency, so those details are not borrowed from nearby SHL models. The strongest source-supported specification cluster is SHL Series, panel-mount plunger, 7.8 mm stainless-steel plunger, SPDT contacts, general-load classification, 15 mΩ contact resistance, 100 MΩ insulation resistance, IP67 protection, and the listed electrical and mechanical durability. These terms keep the page focused on the actual SHL-Q55 configuration without adding unlisted applications or actuator behavior.
