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.

📌 4-20 mA is an active four-wire output (supply and signal fully separate): P1 = +24 V, P2 = 4-20 mA output +, P3 = signal - 4-20 mA output -, P4 = 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.

| P4 | 0 Vdc signal minus / supply minus | PLC analogue input - and supply 0 V |

📌 Note: the negative (-) analogue input of the controller may only go to the sensor 0 V (P4), never to machine 0 V or earth. Dual output: P3 = 0-10 V (forward), P2 = 10-0 V (reverse), sharing P4 as negative / supply ground.

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 |

| Profibus-DP 195 | Profibus A / B | Profibus B / A | 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.
The diagrams only map pins; a full wiring sequence from scratch, including the four-wire and shield-ground order, is in wiring method illustrated.

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.
Q: Are the pin numbers in the wiring diagrams read from the front or the solder side
Use the pin number, not the position on the drawing. On circular connectors the front and solder views are mirrored, and that is where most wiring errors start; check continuity with a meter when unsure.
Q: Can I wire by colour instead of by pin number
No. The colours belong to the factory cable; once it has been replaced or cut they mean nothing. Wire to the pin table, and note that the same pin number does not carry the same function across series.
