Description
The National Instruments CB-37FH Terminal Block, part number 778673-01, is an unshielded connector block designed for horizontal DIN-Rail mounting and is compatible with NI DAQ devices that have 37-pin D-SUB connectors. It features a 37-pin female D-SUB to 37-pin female screw terminal connection, providing a secure screw terminal connectivity for wire gauges ranging from 12 to 30 AWG.
For ease of installation or removal, the CB-37FH is equipped with a spring-latch mechanism that can be operated using a simple flathead screwdriver. This terminal block is capable of handling a maximum voltage of 60 VDC and can pass a current of up to 2.5 amperes, with a voltage limit of 42.4 V. Although not intended for applications requiring strict EMC compliance, its EMC performance can be improved by housing it within a shielded enclosure.
The CB-37FH is designed to endure the rigors of harsh industrial environments, making it a robust choice for various signal connection needs in such settings.
