Product catalog summary
Product Overview: The document provides technical specifications for the 1-Ear Clamp with mechanical interlock, specifically for Product Groups 105 and 155. These clamps are designed for fast and simple installation with visible deformation indicating proper closure. The dimple feature increases clamping force, and burr-free strip edges reduce the risk of damage to clamped parts.
Material Specifications:
  • PG 105: Galvanized or zinc-plated steel band.
  • PG 155: Stainless Steel, Material no. 1.4301/UNS S30400.
  • Corrosion resistance: PG 105 ≥ 144 hours, PG 155 ≥ 1000 hours according to DIN EN ISO 9227.
Size and Series Information: The clamps are available in a size range of 10.5 – 116.0 mm with a width x thickness of 7.0 x 0.6/0.8 mm. Some sizes require a minimum order quantity, and PG 105 is available only on request.
Mechanical Interlock and Installation: The mechanical interlock ensures secure closure, reducing corrosion compared to spot-welding. The maximum diameter reduction is proportional to the open ear width, calculated using the formula: Max. diameter reduction = Ear width (s) / π. Proper sealing requires correct closure of clamp ears during installation.
Installation Data:
  • Size 10.5 – 17.0 mm: Max closing force 1200 N.
  • Size 18.5 – 116.0 mm: Max closing force 2000 N.
  • Recommended tools: HMK 01/S01, HO ME 2000, CP 01.
Assembly Recommendations: Use a constant tool jaw force for closure, known as "force priority closure," to ensure uniform stress and compensate for component tolerance variations. Avoid secondary crimping force.
Order Information: Detailed size ranges and item numbers are provided for ordering, with band width and thickness specified as 7.0 mm and 0.6 mm, respectively.
Contact Information: The document lists contact details for Oetiker's headquarters in Switzerland and various international offices, including Austria, Canada, China, Czech Republic, France, Germany, Hong Kong, Hungary, India, Japan, Netherlands, Spain, South Korea, United Kingdom, and USA.

Ear Clamps with mechanical interlock-3

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...
