August 28, 2013 (FPRC) -- Electro Standards Laboratories, Cranston, RI, has recently added 2 additional BNC Remotely Controllable A/B Switches to their product line up. This group of switches now includes Models 7202, 7302, and 7402. The switches are identical except for the impedance requirement which is 50-, 75-, and 93-Ohm respectively.

Each switch allows the quick connection to any one of two BNC interface devices via the Common port. The port connectors include (3) BNC female connectors labeled A, B and COMMON. The center pin and shell of each BNC connector is switched. The switches feature a front panel pushbutton for manual control and an RS232 Serial port for remote control. The remote control system includes (1) DB9 female Remote connector on the rear panel that accepts ASCII RS232 Serial Data commands for switch position and control. The units retain last switch position in the event of a power loss and continue to pass data. Use of network switches eliminates the need to plug and unplug cables from equipment.

These switches are ideal for sharing laboratory test equipment having a BNC coaxial cable interface. On the company Website, each switch has an individual product page with a full-color detailed application diagram. A specification sheet is also available by simply clicking the Detailed Specs icon on the product page. Electro Standards Laboratories offers custom length 50 -, 75- and 93-Ohm BNC coaxial cables for switch installation.

The power supply that is provided with the switches is a UL approved 100VAC/240VAC, 50Hz/60Hz wall mount module that supplies 12 VDC, 500mA to the unit. This power supply has a 2-prong, US, non-polarized plug. Electro Standards also offers an optional Wide Range Power Module, Catalog Number 517277. This unit is CE, RoHS, and UL listed and is configured as a table mount. The module offers 100VAC/240VAC, 50Hz/60Hz. It features an IEC 60320 C14 inlet. With this optional power module, the 7202, 7302, and 7402 series of BNC A/B switches is ideally suited for international applications.
These switches are designed in a desktop configuration. The switch dimensions are 5.25 W x 7.25 D x 2.0 H (13.3 x 18.4 x 5.1 cm). Each switch weighs approximately 2.0 lbs. (0.91 Kg). The switches are available for export worldwide.
