Quality Engineered Products that Meet Ordinary Location Requirements

Extreme Temperatures

Rated for continuous operation in high temperatures up to 204°C (400°F). Especially useful in steam turbines as well as high heat boilers, dryers, steel processing, and aluminum die-casting. Extreme low temperatures as low as -60°C (76°F).

Cylinder Position Sensing

With their stainless steel housing and sensing faces, probe lengths up to 5", high temperature capabilities, and 3,000 psi pressure ratings, Stroke-to-Go® cylinder position sensors deliver the ultimate reliability and durability in cylinder position sensing.

Extended Sensing

The original "leverlesslimit switches," 10 and 80 Series GO Switches are the ideal replacements for traditional mechanical limit switches. Their sealed contacts, rugged enclosures, no-touch sensing, and snap action response make these switches the ultimate problem solvers for troublesome limit switch applications.

Precision Sensing

Rated for continuous operation in high temperatures up to 204C (400F). Especially useful in steam turbines as well as high heat boilers, dryers, steel processing, and aluminum die-casting. Extreme low temperatures as low as -60C (-76F).

General Purpose

Quality engineered products that meet ordinary location requirements. Suitable for use in multiple industries, such as automotive, marine, military vehicles, manufacturing, amusement parks, material handling, gaming and entertainment, and heavy equipment. Setting the standard for reliable performance.

Hazardous Area Certified

GO Switches are suitable for use in Flameproof/Explosion Proof, Non-Incendive, Intrinsically Safe hazardous areas with IECEx, ATEX, GOST, InMetro, UL, CSA, JIS, KOSHA, and NEPSI.

High Pressure

High pressure options to to 690 bar (10,000 psi). Typical application for hydraulic and pneumatic cylinders.

Submersible Sensors

Available with subsea connectors for continuous submersion. GO Switch SubSea leverless limit switches are submersible to depths of 7,010m/23,000ft and offer trouble-free position sensing in applications such as offshore oil platforms, lock and dam gates, ships and vessels, pin placement detection, wastewater rendering areas.
