optical head OP-305 with RS-232 signal level

The optical head OP-305 is an interface for a bidirectional data exchange between a meter such as power meter, gas meter, heat meter, water meter etc. and a peripheral device via infrared optical waves. The optical reading head is manufactured in accordance with the standard IEC 62056-21 (IEC 1107) and is compatible with all consumption meters that support this European standard.

Our optical head OP-305 has on one end a four-wire cable with serial DB-9 male connector, which can be connected to a peripheral device or Handheld. There is a fix mounted magnetic ring on the other end of the optical reading head, which will be docked on your counter. The output of the optical probe OP-305 is based on serial connection standard RS-232.

Please note that additional, specific software is necessary to exchange data between the consumption meter and your peripheral device.

Of course, we can customize the optical interface OP-305 to your individual needs.
