Magnetostrictive Displacement Sensor: Wiring Diagrams for All Series
Germanjet magnetostrictive displacement sensor wiring guide — pin definitions and wiring for the whole range (Series 12 / 13 / 16 / 17 / 18 / 19 and the 7-pin D70 plug), covering analogue voltage/current, Start/Stop, SSI, CANopen, CANbus, Profibus-DP and EtherCAT/Profinet. Every magnetostrictive displacement sensor wiring diagram is drawn sensor connector → cable → controller terminal, with the not-connected (NC) pins marked, so a site engineer can see at a glance how to wire a displacement sensor without miswiring it. Always wire to the product label and the order code.
⚠️ Wiring golden rules — read first. A wrong connection destroys the sensor and is not covered by warranty.
- Never reverse supply and signal. Do not connect +24 Vdc to a signal output (P2/P3 or Output1/Output2) and do not connect 0 V to a signal pin. The sensor is destroyed immediately and the damage is outside warranty. Correct: +24 V to the supply pin, 0 V to the supply ground pin, signal to the signal pin.
- Supply range: the supply must be 20.4 – 28.8 Vdc (nominal +24 Vdc), low ripple and adequate power (allow ≥40 mA per sensor).
- Use four-core (or more) twisted-pair screened cable, conductor cross-section ≥ 0.2 mm². Our analogue output is four-wire (supply and signal fully separate). Never tie the signal minus to the supply 0 V as in a three-wire scheme — the reading becomes unstable and accuracy drops.
- The negative (-) analogue input of the controller may only go to the sensor 0 V (P4). Do not connect it directly to machine 0 V or to earth.
- Screen earthed at one end only: the cable screen goes to the connector shell and is earthed at the controller end, left open at the sensor end, to avoid a ground loop.
- Confirm the output type before wiring (voltage / current / SSI / CAN / fieldbus). Pin functions differ between output types — always check the table below.
Series 18 magnetostrictive displacement sensor wiring (external, universal · analogue / start-stop)
Non-contact magnetostrictive measurement in an extruded aluminium housing, IP67, for general external mounting on machinery. Analogue voltage/current and Start/Stop digital outputs are available in the standard 4-pin oil-proof plug (DIN 43650), with optional 5-pin M12 A-coded, D60 6-pin M16 and S32/S15 8-pin connectors — check the order code.
▸ Analogue voltage output 0-10 V / 10-0 V (DIN 43650)
| Pin | Function | To controller |
|---|---|---|
| P1 | +24 Vdc supply + | PLC supply +24 V |

| P3 | 0-10 V output + | PLC analogue input + (forward direction) |
| P4 | 0 Vdc signal minus / supply minus | PLC analogue input - and supply 0 V |

📌 Dual output: P3 = 0-10 V (forward travel output +), P2 = 10-0 V (reverse travel output +), both sharing P4 (0 V) as negative / supply ground. One channel is usually enough: take P3 → AI+ for forward, P2 → AI+ for reverse, and wire P4 to AI- and to supply 0 V.

P3 and P4 are not linked inside the sensor — all four conductors are used. At the PLC, P3 goes to analogue input AI- and P4 to supply 0 V; both must be wired, neither may float.

Series 16 magnetostrictive displacement sensor wiring (in-cylinder 16H / 16C)
For in-cylinder mounting (16H hydraulic in-cylinder / 16C miniature in-cylinder), with analogue and SSI outputs. Analogue uses the D60 (6-pin M16) connector; SSI synchronous serial output uses D70 (7-pin M16) or S32 (8-pin M16), or the R02/H02/T02/W02 direct cable options.

For single-channel output only P1/P2/P5/P6 need wiring (P3/P4 may stay open); for dual output wire all of them. Order codes: 001 = 0-10 V, 011 = 10-0 V, 101 = 4-20 mA, 111 = 20-4 mA.

Series 19 magnetostrictive displacement sensor wiring (intelligent digital · D60 six-pin M16 connector)
Series 19 is the intelligent digital family, offering analogue, Start/Stop, CANbus, Profibus-DP and EtherCAT/Profinet interfaces. Analogue and Start/Stop versions mostly use the D60 six-pin M16 connector (or the R02/H02/T02 direct cable); fieldbus versions (CANbus, Profibus-DP, EtherCAT, Profinet) in practice use a dedicated M12/M8 combination connector — see “Fieldbus connector notes” below. The D60 wire-colour table applies to the D60 version of analogue, start-stop and fieldbus units.

📌 Standard D60 wire colours (looking at the sensor pins): P1 black = Output1, P2 white = DC Gnd, P3 yellow = Output2, P4 green = DC Gnd, P5 red = +24 Vdc, P6 blue = 0 Vdc. The screen goes to the shell and is earthed at the controller end. On a single analogue channel, P3/P4 (Output2 and its ground) may be left open — marked “optional” in the diagram; with dual output all pins must be wired.
| Interface model | Output1 (P1 black) | Output2 (P3 yellow) | Supply |
|---|---|---|---|
| Analogue voltage/current 190 / 191 | Output1 (0-10 V / 4-20 mA) | Output2 (10-0 V / 20-4 mA) | P5 red +24 V / P6 blue 0 V |

| EtherCAT 197 / 198 | EtherCAT signal | EtherCAT signal | P5 red +24 V / P6 blue 0 V |
Series 19 fieldbus connector notes (M12 / M8)
Compiled from the Accessories pages of the Germanjet 2024 Catalog. Fieldbus versions normally split “bus in/out” and “24 V supply” across two connectors: one M12 for the bus, one M8 for power. Choose by the connector code in the order code; the actual pin assignment on the delivery label always takes precedence.
| Interface | Order code example | Bus Input | Bus Output | 24 V Power |
|---|---|---|---|---|
| CANbus | 194 D54 / S94 / D34 | 5p M12 A female | 5p M12 A male (D54 / S94) | 4p M8 female (D54) |
| Profibus-DP | 195 D53 / S13 / D63 | 5p M12 B female / 6p D60 female | 5p M12 B male / 6p D60 male | 4p / 3p M8 female (D53 / S13) |
| EtherCAT | 197 Series | 4p M12 D male | 4p M12 D male | 4p M8 female |
| Profinet | 199 D56 / D58 | 4p M12 D male | 4p M12 D male | 4p M8 female (D56) / 4p M12 A female (D58) |
📌 Wiring notes: on a fieldbus version, first check how many connectors the sensor body carries. If there is only one D60 six-pin, wire to the D60 table above. If it is an M12 + M8 combination, the M12 takes the bus and the M8 takes +24 V / 0 V. Profibus uses M12 B-coded, CANbus uses M12 A-coded, EtherCAT/Profinet use M12 D-coded — never mix them up.
7-pin D70 plug magnetostrictive displacement sensor wiring (SSI synchronous serial 192 etc.)
Some models (such as SSI 192) use a 7-pin D70 male plug. Pin 7 is “not connected / NC” — it is left open at the factory and does not need wiring on site. The remaining six pins carry the differential clock/data pair and the supply, with fixed wire colours as below.

📌 Wiring notes: P1 black = Data-, P2 white = Data+, P3 yellow = Clock+, P4 green = Clock-, P5 red = +24 V, P6 blue = 0 V; P7 is not connected — leave it open (the grey dashed NC pin in the diagram). The screen goes to the shell and is earthed at the controller end.

Frequently Asked Questions
Q: Which table do I use for my sensor?
Match the series and the connector first: 18 external, 17 / 16 in-cylinder, 13 mobile, 12 servo cylinder, 19 digital (D60 / M12), 7-pin D70 for SSI. The wrong series table means wrong pins.
Q: Can I join signal minus to the supply 0 V?
No. Analogue outputs are four-wire: the supply pair and the signal pair are fully separate. Joining them creates a ground loop and shifts the reading.
