The RGH25F series readheads have been designed to the relevant EMC standards (BS EN 61000
BS EN 55011), but must be correctly integrated to achieve EMC compliance. In particular, attention to
shielding and earthing arrangements is essential.
NOTE: Class 1M LED product. LED radiation. Do not view directly with optical instruments.
The interface will be fully active <300 ms after power is applied.
The interface and readhead are protected from reverse voltage
and over voltage of up to 12 V.
NOTE: Current consumption figures refer to
unterminated interfaces.
For digital outputs a further 25 mA per channel pair (eg A+, A-)
will be drawn when terminated with 120 Ω.
For analogue outputs a further 20 mA will be drawn when
terminated with 120 Ω.
200 m Vpp maximum @ frequency up to 500 kHz maximum
Renishaw encoder systems must be powered from a 5 V dc
supply complying with the requirements for SELV of standard
EN (IEC) 60950.
