RF Architectural Shielding Products
-
EMI (Electromagnetic Interference) is often used interchangeably with RFI (Radio Frequency Interference). However, EMI can be any frequency of electromagnetic noise, whereas RFI is a relatively narrow range of electromagnetic noise on the EM spectrum. EMI Shielding can be used to mitigate electric and magnetic radiation across various spaces. Radio Frequency (RF) Shielding can be used to mitigate RFI with specifically designed enclosures that can block RFI. As well, RF Shielding can include application of RF Shielding paints, fabrics, and other materials.

Shielding Effectiveness/ Conductivity Test
EM-2107A | 30 MHz – 1.5 GHz
-
The EM-2107A is a standard test fixture for evaluation of the electromagnetic shielding effectiveness of planar material. The fixture is an enlarged section of coaxial transmission line and complies fully with the requirements of ASTM test method D4935-1. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred. The EM-2107A is provided with a reference standard test specimen, a dynamic range specimen. Dynamic range of greater than 80dB is achievable, although the cables and other test system components usually establishes the limiting factors.

High Voltage Switching Systems
HXV Series
-
HXV products are high voltage systems intened for Hi-pot / IR or High voltage switching. They can be configured to drive from 32 to 128 switch points per chassis and can be configured as multiplexer (1xN) or Matrix (NxM) configurations. Stand HXV chassis are used for signals up to 5000 VAC rms ( 7400 V peak ) and can carry up to 5 amps of current. Custom systems can be built up to 25KV. Most of the modules used in these systems are 1xN multiplexers or 2x4 matrix modules that can be combined to form larger multiplexers or matrices. Connector options for standard HXV include 5 way banaba jacks / binding posts, Shrouded Banana Jacks or SHV ( High voltage BNC) if you need to use a high voltage cable with a grounded shield for safety applications. Control options include 10/100BaseT Ethernet LAN, RS232, GPIB or optional manual control. Standard HXV systems use high voltage reed relays. Custom HXV systems up to 25KV use application specific relays and connectors from a variety of vendors based on required specifications.

MAX31855 K-Type Thermocouple Arduino Shield
SEN-30004-K03
-
Four channel MAX31855 digital thermocouple Arduino Shield. Two versions of this shield are avaliable for each thermocouple type: either 'Ch 0-3' (CS pins use Uno/Mega IO pins 7-10) or 'Ch 4-7' (CS pins use Uno/Mega IO pins 3-6), with the only difference being which set of zero-ohm resistors are populated on the board. This allows use of other SPI devices that may be 'hard coded' to specific digital pins on the Arduino, or simply stacking one of each type together to get a total of eight thermocouple channels on one Arduino. The MAX31855K supports a measured temperature range of -270C-1372C with known thermal characteristics and output resolution of 0.25C. Included thermocouple connectors are type-specific to provide proper material continuity as close to the IC as possible. The SEN-30004 is interfaced via 3 or 4-wire SPI and a high-speed level shifter is included to allow the board to plug directly into an Arduino Uno or Mega
