Telecom Markets

ing the angle of hip joint in exoskeletons.
With a body thickness of only 4.4 mm, the CP-1Hx is a contactless angle sensor designed for small space constraints. As a
special variant, the touchless version comprising a separate
magnet unit is available which can be used for measuring the
flap angle of a valve in a flowmeter. The product comes in two
shaft versions and its angular range can be chosen from 50
degrees up to 360 degrees.
Based in Zurich, Pewatron manufactures a broad range of sensors as well as DC brush motors, power supplies and electronic
components.

TT Electronics introduces two new ferrite-based magnetically shielded power inductors for industrial and telecom
applications requiring high frequency power conversion
and robust EMI filtering especially those using fast switching gallium nitride (GaN) semiconductors.
Both are surface mount device (SMD) inductors designed
for use in high frequency DC/DC converter configuration
popular in industrial markets. Their high inductance and
current values offer a switching frequency configuration
range of 100 kHz to 3 MHz making them suitable as a
buck converter or an EMI filter.
"These new SMD inductors offer greater operating temperature ranges in a smaller package than competitive
options," said Raj Singaraju, global product line director.
"Designers now have a clear advantage in addressing the
complex needs of high-power density applications common in today's industrial and telecom equipment markets."
The HM66M series is designed for high frequency power
conversion systems and EMI filter applications, and the
HM78M series for high density and high frequency DC/DC
converter applications. The HM66M is a shielded, miniature low-profile inductor that integrates a ferrite material
core for significant permeability and temperature advantages. Characterized by low losses at high frequencies,
they are ideally suited for power supplies and frequency
converters that operate with fast switching GaN power
semiconductors, said Singaraju.
