The uniform quality and availability of the Series 304 make it the ideal wire for general applications requiring moderate abrasion and moisture resistance, wide temperature capabilities and economy.
Each conductor is covered with a color coded glass braid. This braid is impregnated to enhance abrasion resistance and reduce fraying. The insulated single conductors are laid parallel and covered with another layer of woven glass. A final impregnation is then applied to the glass.
Series 502 is an economical wire that has PVC for the primary and duplex insulation.
The primary and duplex insulation is PVC. It yields a construction that is inexpensive and performs continuously at temperatures up to 220 °F (105 °C).
Series 502 is often used in conduit and wiring trays where its flexibility allows for easy installation. It can be easily stripped using hand tools or mechanical methods.
The SERIES 507 is the most economical fluoroplastic insulated wire. Individual conductors are coated with a layer of color coded FEP. The insulated conductors are then parallel duplexed with an additional layer of color coded FEP. The finished construction has a continuous temperature rating of 400°F (204°C). Abrasion, moisture and chemical resistance exceed most other insulations. This construction is widely used when pulling long lengths of wire through conduit. FEP’s low friction coefficient and abrasion resistance are suited for these applications.
The SERIES 509 was developed specially for use with microprocessor-based systems. The conductors are insulated with color coded FEP. They are then twisted with a copper drain wire. An aluminized polyester tape is wrapped around the conductors and drain wire and then FEP is applied. The finished construction can withstand temperatures in excess of 400°F (204°C). Twisted conductors minimize electromagnetic interference (EMI) and the shield tape eliminates most problems associated with AC “noise” in the sensing circuit.
