Fibre-optic cable assemblies made to order
In launching a unit dedicated to the design, repair and assembly of fibre-optic cable assemblies, you might think Townsend Coates is simply following the crowd.
Bonding heads speed soldering operations
A new family of air-actuated heads is specially designed to address pulsed heated hot bar reflow soldering applications.
This constant force spring provides a cost effective and reliable, full 360-degree-screen termination that requires no special tooling to install on to the backshell and is easy to rework.
Both single and double braids may be used with the 91 series adapters to produce a DC contact resistance of less than 1mohm.
All adapter cable entry sizes, in both straight and angled forms, are covered with five spring sizes.
A particularly useful feature is that the spring may be re-opened and re-used in the field to allow for repair or service of the connector without scrapping any part of the shielding system.
The electrical and mechanical characteristics of this termination are unaffected by shock and vibration throughout an operating temperature between -65 and +150C and the spring termination may be safely used in corrosive atmospheres.
Comprehensive, independent witnessed test reports are available covering thermal cycling to MIL-STD-202E Method 107G, vibration testing to MIL-STD-176-1 and shock testing to MIL-STD-1344A Condition G.
The Polamco 91 Series has been specified and used worldwide by many leading companies for a wide variety of applications, ranging from armoured vehicles, communications, marine electronics and land based systems.
Acal TC is now the main UK stockist for Polamco backshells for MIL-DTL-D38999.
