To accomplish this, Bendix recommended that an audio transformer in series with a 2k[OHM] resistor be used to provide a simulated wheel speed sensor network.
The audio transformer used for the wheel speed sensors is the Jensen JT-11-BMCF shown in Figure 20.
Audio Transformers and the EC-60 Wheel Speed Sensor Testing
In comparison, you can pick up an audio transformer, which will also do a good job of isolating you electrically while still allowing you to pass a signal.
Typically, audio transformers take an unbalanced signal, but you can also find higher-end boxes designed to take XLR or line-level 1/4" inputs and pass the signal on to the rest of your equipment properly.
With this problem solved, I stepped into the room in back of the Carola mainframe to see how the eight-foot-high RCA audio transformer
As a franchise distributor of MoxiE Inductor Corporation, New Yorker Electronics now supplies its full line of Chip Inductors, RJ45 Connectors, Power Inductors, LAN Transformers, Power Transformers, EMI/RFI Products, Inverter Transformers, Chokes, Current Sensors, Air Coils, plus audio magnetic products and audio transformers
, and more.
Power and audio transformers may contain internal winding-to-winding screens, a copper eddy-current band, or a complete metal-box shield, all of which contribute to EMC performance.
Audio transformers must pass a relatively wide band of frequencies with low distortion.
Amgis also offers a assortment of other toroidal products, including audio transformers
