Self-extinguishing cable sealant

In electrical equipment that generates heat, cable bundles must be durably protected against high temperatures. With Terostat 3631 FR, Henkel has developed a flame retardant and easily applied butyl sealant which is especially suitable for applications where low flammability is essential.

Unlike conventional butyl-based sealants, Terostat 3631 FR easily withstands continuous exposure to temperatures up to 105°C and also has self-extinguishing properties in the event of a fire. As a result, Terostat 3631 FR is suited for use as a longitudinal water-repellent sealant for cable bundles in electric ovens, microwaves, heating systems or tumble dryers.

In addition to high-grade thermal protection, a further advantage offered by the sealant is its easy handling and excellent resistance to water and moisture. As a soft-moldable compound, Terostat 3631 FR is simply applied manually to seal off the cable bundle. This eliminates the fiddly work required in many cases to thread cables through grommets. Moreover, when applied hot, the sealant can also be processed automatically.

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

IDEC Releases New Line of High Efficiency Power Supplies
