Output
HTL
= HTL output with excitation 24 VDC, output 24 V
TTL
= TTL output with excitation 5 VDC, output TTL/RS422
TTL24V
= TTL output with excitation 24 VDC, output TTL/10 mA
Reference pulse/ end position signal/ status signal
Z0
= A/B w/o reference pulse / Z1 = A/B with reference pulse Z
Z2
= A/B with end position signal / *Z3 = A/B with reference pulse
and status signal
(Option Z3 only for non-diferential output, single ended)
Cable length (in m, standard 2 m)
Connection
S
= Cable output, open end
P
= Connector D-sub, 9 pin, at the cable end
