Arc Suppression Diode A diode is connected in parallel with the coil. This diode limits the “reverse EMF spike” generated when the coil deenergizes to 0.7 volts. The diode cathode is connected to the positive side of the coil and the anode is connected to the negative side. Date Code All switches are marked with either a unique serial number or a date code. Date codes are in accordance with MILSTD-1285 Paragraph 5.2.5 and consist of four digits. The first two digits define the year and the last two digits define the week of the year (YYWW). Thus, 1032 identifies switches that passed through final inspection during the 32nd week of 2010. Failsafe A failsafe switch reverts to the default or failsafe position when actuating voltage is removed. This is realized by a return spring within the drive mechanism. This type of switch requires the continuous application of operating voltage to select and hold any position. (Multi-position switches are normally open with no voltage applied). Indicator Indicators tell the system which position the switch is in. Other names for indicators are telemetry contacts or tellback circuit. Indicators are usually a set of internally mounted DC contacts linked to the actuator. They can be wired to digital input lines, status lights, or interlocks. Unless otherwise specified, the maximum indicator contact rating is 30 Vdc, 50 mA, or 1.5 Watts into a resistive load. Performance Parameters vs Frequency Generally speaking, the RF performance of coaxial switches is frequency dependent. With increasing frequency, VSWR and insertion loss increase while isolation decreases. All data sheets specify these three parameters as “worst case” at the highest operating frequency. If the switch is to be used over a narrow frequency band, better performance can be achieved. Actuator Current vs Temperature The resistance of the actuator coil varies as a function of temperature. There is an inverse relationship between the operating temperature of the switch and the actuator drive current. For switches operating at 28 VDC, the approximate actuator drive current at temperature, T, can be calculated using the equation: IT = IA [1 + .00385 (T-20)] Where: IT = Actuator current at temperature, T IA = Room temperature actuator current – see data sheet T = Temperature of interest in °C Magnetic Sensitivity An electro-mechanical switch can be sensitive to ferrous materials and external magnetic fields. Neighboring ferrous materials should be permitted no closer than 0.5 inches and adjacent external magnetic fields should be limited to a flux density of less than 5 Gauss. Isolation Isolation is the measure of the power level at the output connector of an unconnected RF channel as referenced to the power at the input connector. It is specified in dB below the input power level. Switching Time Switching time is the total interval beginning with the arrival of the leading edge of the command pulse at the switch DC input and ending with the completion of the switch transfer, including contact bounce. It consists of three parts: (1) inductive delay in the coil, (2) transfer time of the physical movement of the contacts, and (3) the bounce time of the RF contacts. TTL Switch Driver Option As a special option, switch drivers can be provided for both failsafe and latching switches, which are compatible with industry-standard low-power Schottky TTL circuits. © 2013 TELEDYNE RELAYS (800) 284-7007 • www.teledynecoax.com CCRS-53S/CRS-53S Page 7 CCRS-53S\CRS-53S\082013\Q3 Series CCRS-53S/CRS-53S Miniature DC–26.5 GHz Failsafe 2P3T Coaxial Switch COAX SWITCHES FAILSAFE CCRS-53S/CRS-53S PART NUMBER LIST PART NO. * PART NO. 1 CCRS-53SXC 43 CRS-53SX0-MS 2 CCRS-53SXC-D 44 CRS-53SX0-S 3 CCRS-53SXC-DM 45 CRS-53SX0-T 4 CCRS-53SXC-DMS 46 CRS-53SX0-TM 5 CCRS-53SXC-DS 47 CRS-53SX0-TMS 6 CCRS-53SXC-M 48 CRS-53SX0-TS 7 CCRS-53SXC-MS 8 CCRS-53SXC-S 9 CCRS-53SXC-T 10 CCRS-53SXC-TM 11 CCRS-53SXC-TMS 12 CCRS-53SXC-TS 13 CCRS-53SX0 14 CCRS-53SX0-D 15 CCRS-53SX0-DM 16 CCRS-53SX0-DMS 17 CCRS-53SX0-DS 18 CCRS-53SX0-M 19 CCRS-53SX0-MS 20 CCRS-53SX0-S 21 CCRS-53SX0-T 22 CCRS-53SX0-TM 23 CCRS-53SX0-TMS 24 CCRS-53SX0-TS 25 CRS-53SXC 26 CRS-53SXC-D 27 CRS-53SXC-DM 28 CRS-53SXC-DMS 29 CRS-53SXC-DS 30 CRS-53SXC-M 31 CRS-53SXC-MS 32 CRS-53SXC-S 33 CRS-53SXC-T 34 CRS-53SXC-TM 35 CRS-53SXC-TMS 36 CRS-53SXC-TS 37 CRS-53SX0 38 CRS-53SX0-D 39 CRS-53SX0-DM 40 CRS-53SX0-DMS 41 CRS-53SX0-DS 42 CRS-53SX0-M X = 1 (28Vdc), 2 (15Vdc), 3 (12Vdc) and 4 (24Vdc) CCRS-53S/CRS-53S Page 8 SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE © 2013 TELEDYNE COAX SWITCHES CCRS-53S\CRS-53S\082013\Q3
