Quick Selection Table: Stroke, Accuracy, Output and Protection on One Page

Selecting a magnetostrictive displacement sensor is most tedious when parameters are flipped among a dozen series. This article compresses the Germanjet full-range core parameters into one quick-reference table: stroke, accuracy, output signal, protection class and positioning in one sentence. Pressure rating, cylinder-cap interface and resolution are written by series from — do not put Series 16’s 530 bar, Series 17’s 600 bar and Series 19 in-cylinder 300/600 bar on the same row. Lock the direction from the table first, then open the corresponding product page for detailed specifications.

Magnetostrictive displacement sensor selection quick-reference table — Full-range magnetostrictive displacement sensor selection at a glance

Cylinder-integrated (inside the hydraulic cylinder) at a glance

Series	Range	Accuracy / resolution	Output	Protection / pressure / interface	Positioning
Series 16	50–7600 mm	16-bit D/A 0.0015% (min. 1 μm)	160 voltage / 161 current / 162 SSI	IP67; 350 working / 530 bar peak; cap Ø18G7	Flat electronics housing, cylinder-integrated
Series 17	100–4000 mm	Analogue resolution infinite (controller A/D); non-linearity <±0.02% FS (min. ±90 μm)	Voltage / current / Start-Stop	IP65/IP67; 350 / 600 bar; cap M18×1.5	Electronics housing separable from the pressure tube
19H	75–475 mm	16-bit D/A	Analog / digital / fieldbus	IP67; 300 working / 600 bar peak	Cylinder-integrated, all stainless steel
16R/16T	75–2200 mm	16-bit D/A	Dual / triple independent outputs	IP67; 350 / 530 bar; Ø18G7	Dual / triple redundancy, safety-critical
16E	75–7600 mm	16-bit D/A	Single / redundant output	IP68; peak as Series 16, 530 bar	Harsh environment, salt-spray resistant
17EX	50–4000 mm	Same analogue wording as Series 17	Multiple protocols (including fieldbus)	IP67, intrinsically safe; 350 / 600 bar; M18×1.5	Zone 0/1/2 hazardous areas

Piston-rod bore lower limit is ≥12.7 mm (Ø10 rod) on all of the above. Ø13 mm is the Series 17 cylinder-cap through-hole, not the piston-rod bore.

External (rod / rail) at a glance

Series	Range	Accuracy / resolution	Output	Protection	Positioning
Series 12	50–2500 mm	120 infinite resolution; 121 is the 16-bit D/A	Analogue voltage/current + Start-Stop	IP65/IP67, not pressure-containing	Wall-thickness-control servo cylinder end cap, DIN 43650
Series 18	50–4000 mm+	Analogue resolution infinite; non-linearity <±0.02% FS (min. ±90 μm)	Analog + Start-Stop	IP65/IP67, not pressure-containing	External rod / rail; four-pin voltage type: see wiring red lines
19P	125–4050 mm	16-bit D/A	Analog / digital / fieldbus	IP67	External rod, aluminium profile housing
19D	75–475 mm	16-bit D/A	Analog / digital / fieldbus	IP67	Split-type, electronics housing mounted remotely
19F	2500–7600 mm	Analogue 16-bit D/A	Analog / digital / fieldbus	IP67; front dead zone 50/130 mm	Flexible tube, non-ferromagnetic guide tube

Mobile hydraulics at a glance

Series	Range	Accuracy / resolution	Output	Protection	Positioning
Series 13	50–2500 mm	Per ordered model	Voltage / analog / CANopen	IP68→IP69K	Mobile machinery, 25 g vibration
13C	50–2500 mm	Per ordered model	0.1-4.9 V voltage	IP68→IP69K	Compact, low power, voltage output
13R	75–450 mm	Per ordered model	Dual-channel redundant output	IP68→IP69K	Redundant output, safety-critical

Fieldbus types at a glance (Series 19 digital interfaces)

Series	Protocol	Features	Interface
191	Analog	16-bit D/A, dual-magnet minimum 76 mm	D60 6-pin M12
192	SSI	Absolute position, 8-32 bit	D70 7-pin
194	CANopen	DS-301, 20-1000 kbit/s	D60 6-pin
195	Profibus	DP, up to 12 Mbit/s	D53 dual M12
197	EtherCAT	DC synchronisation, 100 Mbit/s	D56 daisy-chain
198	EtherCAT	Single M12 8-pin integrated	M12 8-pin
199	PROFINET	RT/IRT, encoder Profile 4.1	D56+M8

Lock the series in three steps

Step 1: decide the mounting method — cylinder-integrated choose 16/17/19H, external rod choose 12/18/19P/19D, extra-long stroke choose 19F, mobile machinery choose Series 13. Step 2: decide the output — Series 16 can be 160/161 analogue or SSI; analogue is also 191 or Series 12/18 codes, fieldbus 194/195/197/199 by PLC protocol, safety redundancy 16R/16T/13R. Step 3: check pressure rating and interface by series — Series 16 is 350/530 bar + Ø18G7, Series 17 is 350/600 bar + M18×1.5, 19H is 300/600 bar.
