Principles, selection, installation, wiring, accuracy and troubleshooting — plus typical applications in injection molding, hydraulics, wind power and steel.
162 and 192 share one table: longer cable, lower maximum rate; minimum clock spacing 48 μs. Occasional huge numbers — drop the clock first. Patterned jumps — check Gray versus binary.
On 4-20 mA the start of stroke is still about 4 mA; a broken loop falls near 0. On 0-10 V, 0 V cannot tell zero from an open cable. Check the lamp, then measure at the sensor — do not swap the rod first.
Advantages and disadvantages of 4-20 mA, 0-10 V, SSI, Start-Stop, CANopen, Profibus DP, EtherCAT and PROFINET. Look at the controller ports first, then stroke.
Industrial Ethernet includes PROFINET (199) and EtherCAT (197/198). Choose by the PLC master, not by which name sounds newer.
Serial fieldbuses include 194 CANopen and 195 Profibus DP. CAN’s physical layer is not RS-485. Compare the trade-offs, then follow the master.
Series 16 SSI is 162; Series 19 SSI is 192. Bit length, D70, baud vs cable and 48 μs clock spacing are the same; mounting and pressure are not.
16T is one magnet acting on three independent waveguides and electronics — not three sensors. Do not mix it with 16R dual-channel. Pressure stays 350 / 530 bar.
16E keeps the Series 16 cap Ø18G7 and 350/530 bar. What is upgraded is the IP68 fully enclosed housing — not a different pressure rating.
The Series 19 analogue programmer 1700 951 018 changes zero and end on the sensor. PLC two-point (Slope / Datum) is a different layer. Do not turn both at once.
Look at the lamps first: green on / red off is OK; both on means no magnet (including leaving the valid stroke). Then measure voltage or check the magnet — do not strip the head first.
Pick the connector family by output: Series 12 DIN 43650, 162/192 SSI D70 seven-pin, 191/194 often D60 six-pin, EtherCAT and mobile hydraulic often M12. Wrong pin count means no comms or a burned analogue head.
Electrical outputs by series: Series 16 is 160 voltage / 161 current / 162 SSI; Series 18 is 180–185; Series 19 is 190–199. 162 is Series 16 SSI; 192 is Series 19 SSI — do not mix them.
