M12 Inductive Proximity Sensor PNP N.C — 8mm / 10mm Non-flush | KRONZ

M12 Inductive Proximity Sensor -- PNP Normally Closed (N.C) Series
8 mm / 10 mm non-flush detection * 10-30 V DC * IP67 * 4-pin M12 connector

One-line positioning: The fail-safe choice for European PLCs and export-bound equipment. PNP current-sourcing output combined with normally-closed logic -- the output stays at 24 V during normal operation, and any wire break, supply loss, or sensor fault kills the output and triggers the alarm.

Models on this page: IN8-M12PC68-M0A/D, IN8-M12PC50-M0A/D, IN10-M12PC68-M0A/D, IN10-M12PC50-M0A/D

Product Overview

What this series solves

Normally-open sensors hide their faults. If the cable is cut, the connector is loose, or the supply drops, the PLC sees exactly the same state as "no metal present" -- and the line keeps running. The failure is silent until something crashes or a batch goes bad.

PNP normally-closed sensors invert that logic: the output sources 24 V during normal operation, and any abnormal condition causes the output to disappear. The PLC detects "voltage lost" and triggers a stop and an alarm. This is the fail-safe principle, delivered on the source (PNP) side for European PLCs and export equipment.

How PNP N.C works

PNP output is current sourcing. The internal PNP transistor has its emitter tied to L+. The N.C variant inverts the logic of N.O:

No metal target -> transistor on -> output pin sources ~L+ (24 V), load is energized -> PLC input reads "1"
Metal enters the range -> transistor off -> output pin goes high-impedance, load de-energizes -> PLC input reads "0"

The load is wired between OUT (black, Pin 4) and L− (blue, Pin 3) -- the same wiring position as PNP N.O. Only the internal logic differs. When you retrofit a PNP N.O station with PNP N.C, the cabinet wiring stays as it is.

When to choose PNP N.C

Your situation	Choose it?
You need fail-safe -- wire break must trigger an alarm	✅
PLC input module is source / common-minus (Beckhoff and other European PLCs)	✅
Equipment is exported to Europe or North America with safety logic	✅
Used as a safety gate, guard interlock, or in-position check	✅
You only need a simple "target arrived" check, no safety logic	❌ pick PNP N.O for simplicity
PLC is sink / common-plus (Mitsubishi, Omron, Japanese PLCs)	❌ pick NPN N.C

IN8 vs IN10 -- how to pick between the two distances

IN8 series -- 8 mm detection range, 500 Hz switching -- faster response
IN10 series -- 10 mm detection range, 400 Hz switching -- more installation margin

Both share the M12 × 1 mm cylindrical thread and non-flush (unshielded) installation. Same datasheet, same mounting logic.

Key Features

1. Normally-closed logic -- faults surface, not hide

During normal operation the output sources 24 V. Cable break, M12 connector loose, 24 V supply lost, sensor itself failed -- any of these kills the output and the PLC captures it instantly. Turns "silent failure" into "loud alarm."

2. PNP current-sourcing, direct to European PLCs

The output plugs straight into the source input, Beckhoff, or Schneider modules -- no interposing relay, no level shifter. Drop-in for export-bound equipment.

3. Designed for safety interlocks and in-position checks

Safety gate closed -> metal flag enters the range -> output opens -> machine allowed to start. Gate opens -> output returns -> safety circuit acts. Same idea for confirming that a workpiece is still in the fixture (drop-out triggers the alarm).

4. Same wiring as PNP N.O -- zero rewiring when you upgrade

The load is wired between OUT and L−, exactly as on PNP N.O. Upgrading from N.O to N.C requires no wiring change -- only invert the input logic in the PLC program. Retrofit projects are particularly easy.

5. Two detection ranges on one page

Choose 8 mm at 500 Hz for high-speed applications, or 10 mm at 400 Hz when the target has more play.

6. Non-flush (unshielded) -- longer range from the same M12 footprint

The unshielded structure lets the magnetic field spread sideways, giving a longer rated range than the flush variant. The trade-off is the free metal space around the sensing face -- see Configuration Details.

7. IP67 + −25…70 °C

IP67 per IEC 60529: dust-tight and protected against temporary immersion. Operating temperature covers −25 °C cold storage to +70 °C cabinet-side mounting.

8. Nickel-plated brass + PBT sensing face

Nickel-plated brass housing for impact and corrosion resistance. Blue PBT sensing face, wear-resistant and insensitive to metal swarf. Two hex nuts (17 mm across flats) resist long-term vibration loosening.

9. Field-replaceable M12 connector + triple electrical protection

4-pin M12 A-coded male connector (IEC 61076-2-101) for quick cordset replacement on the floor. Built-in short-circuit, reverse-polarity and power-up pulse protection -- the sensor survives commissioning mistakes.

Safety-circuit application example

Safety gate CLOSED -> metal flag enters range -> N.C output OPENS -> machine may start
Safety gate OPEN -> metal flag leaves range -> N.C output CLOSES -> machine stops
Cable cut / 24 V lost / sensor fault
-> output disappears -> instant stop and alarm (fail-safe)

90° right-angle connector height	34	20
Mounting thread	M12 × 1 mm	M12 × 1 mm
Nut across flats	17	17

Mounting requirements (non-flush)

Free metal space around the sensing face. Non-flush sensors let the magnetic field expand sideways. Without sufficient clearance, the effective range collapses. Recommended free space ≥ 3 × Sn (≈ 24 mm for the 8 mm body, ≈ 30 mm for the 10 mm body). Side-by-side sensors also need adequate spacing to prevent mutual interference.
If you must flush-mount. This series is unshielded. Switch to a flush (shielded) variant if side clearance is impossible.
Tightening torque. Suggested maximum 15 N*m to avoid housing deformation.
Safety-point placement. Mount interlocks where they cannot be easily struck. Consider a protective bracket. Route the cable away from power conductors.

Typical applications

Industry	Use case
Safety guarding	Safety-gate / guard-door interlock, light-curtain bypass confirmation
Industrial automation	Workpiece in-position check (drop-out triggers alarm), fixture-clamp confirmation
Packaging machinery	Guard in-place, foil / carton missing detection
Material handling	Pallet in-position, stack-height over-limit detection
Machine tools	Guard interlock, tool in-position detection
Export equipment	European / American PLC integration with fail-safe logic
