Product Description
Characteristics
Receiver Type | Narrowband tuned radio frequency receiver with automatic gain control, reception frequency: 77.5 kHz, bandwidth approx. 40 Hz |
Type of Antenna | Build in ferrite antenna |
Control Elements | In case of stationary installation it is advisable to position the receiver in an optimal way. The case should be aligned at a right angle to the direction of the transmitter (Frankfurt). In normal applications it should be mounted with distance to solid steel and to TVs or computer monitors. When mounting the receiver near to metal the received signal may be deaden (attenuation), but the field-distortion causes an easier alignment of the antenna because of the ''nearly-360°-character'' In this case a function test is necessary. |
Pulse Outputs | Demodulated time marks for further processing TTL level (when 5V supplied): Vdd - 1V (high) typ. 0.1V (low) Pulse width: 60...130msec (DCF-binary ''0'') 160...230msec (DCF-binary ''1'') |
Electrical Connectors | 4-wire cable The cable can be configured in all lenghts |
Operating Voltage | 3.5 V ... 5 V |
Form Factor | Unbreakable plastic case |
Current Draw | 1.2V...5.5V @ 10mA (both LEDs bright) @ 1mA in power down mode |
Physical Dimensions | 60mm x 50mm x 20mm (length x width x height) |
