Product catalog summary
Overview: The document is a technical data sheet for Oetiker's 1-Ear Clamp with mechanical interlock, covering Product Groups 105 and 155. It provides specifications, installation guidelines, and ordering information for these clamps.
Specifications: The clamps are available in two material types: PG 105 (galvanized or zinc-plated steel) and PG 155 (stainless steel, Material no. 1.4301/UNS S30400). Corrosion resistance is rated at ≥144 hours for PG 105 and ≥1000 hours for PG 155 according to DIN EN ISO 9227. The size range is from 10.5 to 116.0 mm with a band width of 7.0 mm and thickness options of 0.6 or 0.8 mm.
Mechanical Interlock: The clamp features a mechanical interlock that secures closure without spot-welding, reducing corrosion. The maximum diameter reduction is proportional to the open ear width, calculated using the formula: Max. diameter reduction = Ear width (s) / π.
Installation Guidelines: Proper installation requires tools designed or endorsed by Oetiker. The closing force varies by size, with a maximum of 1200 N for sizes 10.5 – 17.0 mm and 2000 N for sizes 18.5 – 116.0 mm. The clamp ear should be closed with a constant tool jaw force, known as "force priority closure," to ensure uniform stress and compensate for component tolerance variations.
Order Information: The document lists various size ranges and corresponding item numbers for ordering. The clamps are available in specific size increments, and some sizes require a minimum order quantity.
Contact Information: The document provides contact details for Oetiker's headquarters in Switzerland and various international offices, including locations in Austria, Canada, China, France, Germany, and more.

1-Ear Clamp with mechanical interlock  PG 105 & 155 Assembly recommendations The clamp ear should be closed with a constant tool jaw force, this practice is referred to as “force priority closure”. This assembly method ensures that a uniform and repeatable stress is applied to the application with a constant tensile force on the mechanical interlock. Employing this methodology when closing 105 & 155 series clamps will compensate for any component tolerance variations, and ensure that the clamp applies a constant radial force to the application. Fluctuations in component tolerances are absorbed...
