Renishaw encoder systems have been designed to the relevant EMC standards, but must be correctly
integrated to achieve EMC compliance. In particular, attention to shielding arrangements is essential.

T103x with Ti0000 <100 mA
T103x with Ti0004 – Ti20KD or TD4000 – TD0040 <200 mA
NOTE: Current consumption figures refer to unterminated
systems.
For digital outputs a further 25 mA per channel pair
(eg A+, A−) will be drawn when terminated with 120R.
For analogue outputs a further 20 mA in total will be
drawn when terminated with 120R.
Power from a 5 V dc supply complying with the
requirements for SELV of standard IEC BS EN 60950-1.

Type Magnetic actuators; with dimple triggers Q limit, without dimple triggers P limit
(see 'RKLC20-S scale installation drawing')
Trigger point The limit output is nominally asserted when the readhead limit switch sensor passes
the limit magnet leading edge, but can trigger up to 3 mm before that edge
