OEM 1-Channel Fiber Optic Signal Conditioner PCB Module
FOTEMP1-OEM-MNT
-
The FOTEMP1-OEM-MNT is a small form factor PCB interface module designed for low cost insertion of high precision GaAs-based fiber optic temperature sensor technology into OEM applications where common electrical temperature sensors and thermocouples cannot be used. The OEM interface product is compatible with all TS series fiber optic temperature probes. The sensors are entirely non-metallic and electrically passive, providing immunity to EMI, RFI, MR, microwaves and radiation is required.

High Voltage Op Amplifiers ≥12V
-
High supply voltage op amps are used in systems that demand the widest dynamic range with the best signal-to-noise ratio. Engineers turn to Analog Devices for high voltage amplifiers that deliver industry-leading performance. Increasingly, new high voltage amplifiers also offer features to improve system performance, cost, and robustness while easing the complexity of system design. New features include integrated input overvoltage protection (OVP), on-chip electromagnetic interference (EMI) filtering, higher electrostatic discharge (ESD) immunity, and greater resistance to latch-up in both powered and unpowered operations.

Mezzanine System
5033
System
ECM P/N 5033 provides eight channels of RS485 / RS422 I/O. The 110 ohm termination for each channel is enabled or disabled in software. Disabling termination saves power by eliminating unneeded or redundant termination. Speeds of up to 20 Mega bits per second are possible, but this design also features a 250K bits per second slower edge rate mode. The 250K bit mode is valuable when EMI is more of a concern and throughput is not important. All channels power up as inputs with the outputs disabled.

Faraday Cages
-
LBA's EMFaraCage® faraday cages are EMI and RFI shielding boxes and RF test enclosures that bring convenience to device testing. Faraday cages are ideal for isolating critical systems in high field RF environments or wherever RF ingress or egress must be minimized. Security, production testing, biomedical research and semiconductor testing are only a few of the many areas where EMFaraCage® faraday shielded enclosures are employed. EMFaraCage® faraday cage enclosure systems are fully featured to support a wide variety of test missions. The standard faraday cages include effective power, dataline and RF signal isolation in large test volumes. EMFaraCage® faraday cages are much more affordable than shielded room solutions and offer the convenience of portability.
