Overview
The GO Switch Model 71 has the smallest diameters (3/8”) of any round leverless limit switch, and is used extensively in factory automation applications.
Mechanically, Model 71 has no external moving parts, no springs or cams, and no reed element, so there is nothing to wear or fail. Its contact chamber is potted and sealed from moisture or contaminants and is completely protected in a one-piece stainless steel housing, including the sensing face. Unlike magnetic reed switches, it is not susceptible to contact teasing, chatter, bounce, or welding.
Electrically, Model 71 delivers the most flexibility in the industry. Its environmentally sealed dry contacts are rated 4amp/120VAC, 3amp/24VDC, and 0.5 amp/125VDC and is suitable for both high and low electrical loads. The 71 can be wired AC or DC, N/O or N/C, consumes no power to operate, and has no current leakage or voltage drop.
Environmentally, Model 71 leads the industry with UL and CSA certification for use in flameproof, explosion proof, non-incendive, intrinsically safe, and general-purpose applications. In addition, Model 71 is suitable for extreme temperatures (-50°C to 204°C), extreme pressures (up to 10,000psi), and extreme depths (down to 7010 meters).
