Key Application Keywords

Jig positioning, cylinder end-position detection, conveyor line counting, machine tool limit monitoring, metal detection in narrow spaces, material handling position feedback, signal acquisition for automated machinery

Selection & Replacement Notes

Suffix definition: no suffix = 2m fixed cable; `/AS` = M8 3-pin straight connector; `/0,3M` = short lead
Domestic equivalent replacement: rectangular inductive proximity sensor with identical size, 2mm flush-shielded, PNP NO output
Installation note: flush mount; sensing face can be embedded into metal brackets without reduction of rated sensing distance.

Troubleshooting Guide

No output: first check 24V power supply and polarity; verify no reverse wiring

Unstable signal: check voltage drop, gap between sensor and metal target, nearby strong magnetic interference and mounting clearance

LED does not light up: missing power supply or internal short circuit

NPN Version with Identical Mechanical Outline (IS Series, 27.8×10.2×16, flush 2mm, 3-wire DC)

Remark: IS series is originally PNP dominant; NPN models carry suffix BOKG

IS5002: IS-3002-BOKG, NPN normally open, 2m PVC cable; fully interchangeable with IS5001 with identical mounting holes

IS5036: IS-3002-BOKG/AS, NPN NO, M8 3-pin straight connector (counterpart of IS5035)

IS5069: IS-3002-BOKG/0,3M/AS-610, 0.3m short cable + M8 connector (counterpart of IS5068)

Wiring: BN=L+, BU=0V, BK=NPN output; supply 10~30V DC. All other parameters (switching frequency, temperature range, IP67, protection) match IS5001 completely.

On-site Installation Guidelines

Tightening torque

PBT plastic housing; tightening torque must be below 0.5 N·m to prevent cracking; use thin flat washers to disperse clamping force.

Cable routing & wiring

Standard 2m PVC cable (3×0.14 mm²);

Brown = +24V, Blue = 0V, Black = PNP signal;

Avoid routing alongside power cables and servo motor wires to prevent EMI interference. Use shielded cable or signal filters for long-distance wiring.

Built-in short-circuit & reverse polarity protection; avoid hot-plugging under power.

Environmental suitability

IP67 rated; resistant to cutting fluid, cooling water and dust. Not suitable for continuous immersion or strong corrosive solvents (acetone, strong acid/alkali).

Ambient temperature range: -25～+80 ℃; add heat insulation if installed near heating blocks or injection mould slides.

Gap adjustment

Recommended working gap: 0.5～1.2 mm (leave safety margin). Do not operate continuously at the maximum 2mm gap; vibration will cause signal dropout.

Yellow LED lights up when metal is detected; use the LED for quick commissioning.

Switching frequency limit

Rated frequency: 800 Hz (max 800 pulses per second). For field application, limit the frequency to ≤400 Hz. Not recommended for high-speed pulse counting or high-frequency vibration detection.

Important Limitation

This is a standard position sensor, NOT a safety-rated device. Do not connect it to safety circuits, safety gates or emergency stop protection loops.

Only detects ferrous/non-ferrous metals; no response to plastic, film or wood.

Comparison Table: IS5001 Ultra-Thin Rectangular vs Standard Cylindrical Proximity Sensors

Item	IS5001 IS-3002-BPKG Ultra-Thin Rectangular	Standard M8/M12 Cylindrical Inductive Sensor (e.g. ifm IE5001)
Dimensions	27.8×10.2×16 mm, ultra-flat	Cylindrical M8/M12/M18; requires radial installation space
Mounting	Flush shielded; fits narrow slots, cylinder side faces and gripper gaps	Flush / non-flush options; threaded body requires radial clearance
Sensing distance	Fixed 2 mm	M8:1.5~2 mm; M12:4 mm; M18:8 mm; multiple range options
Switching frequency	800 Hz	M8 typically 2000 Hz; M12 approx 1000 Hz; wider high-frequency options
Fixing method	Side-mounted with screws	Threaded screw-in + lock nut; faster installation
Advantages	Ultra-thin body, ideal for space-critical locations; flush mounting prevents collision damage	Wide model range, flexible sensing distances, universal spare parts, fast commissioning, broad price options
Disadvantages	Long body despite thin thickness; short 2mm sensing range; higher price than M8 types	Radial protrusion; prone to collision on slim cylinders and compact grippers
Typical Applications	Slim cylinders, finger grippers, narrow-slot jigs, small tool magazine positions	General limit detection, conveyor counting, machinery with ample mounting space
Protection	IP67	Mostly IP67
Output	PNP NO (NPN version IS5002 available with same outline)	PNP/NPN, NO/NC; full output options
Side Metal Immunity	Flush-shielded (can be embedded in metal brackets); keep ≥5mm clearance from side metal	Flush types can be embedded; non-flush types require large metal clearance
