Meter reading optical probe OP-500 with TTL voltage level (0 V to 3.3 V)

The optical probe OP-500 is an interface for a bidirectional data exchange between a meter such as power meter, gas meter, heat meter, water meter etc. and a microcontroller 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 probe OP-500 has on one end a four-wire cable without any connector, which can be connected to a peripheral device or a plug. 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-500 is based on serial connection standard with TTL voltage level (0V to 3.3V).

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-500 to your individual needs.
