SENSOR 4008610350 M5X0.5 L 25/30mm SN 0.8mm NO 4-008-61-0350 Spare Parts for Homag

When a Homag machine stops indexing or starts reporting position faults at one station, the sensor at that point is the first thing to pull. A worn or dead sensor at 0.8 mm sensing distance will not trigger the normally open output, so the control sees no target and the cycle faults out.

It is an inductive sensor with an M5x0.5 thread, made in a length of 25 mm or 30 mm, and it fits Homag woodworking machines. To confirm the fit, read the part number off the old body: 4008610350 or 4-008-61-0350. Measure the threaded length and confirm the output is normally open before you order.

Check the thread in the mounting bracket first, then check that the 0.8 mm gap to the target can be set with the sensor seated. The M5x0.5 thread lets you set that gap by turning the body, then lock it. Too much gap and the NO output never closes, so the machine reads a missing target.

Send the part number, the thread size and the length you need with your enquiry, and state whether the machine needs the 25 mm or 30 mm body. SHUNHONGYU supplies various woodworking machine parts, so put the machine model and the old sensor number in the message and ask what is available.

What the specification fixes, and what it leaves to the machine:

• Thread fit at the bracket — An M5x0.5 thread seats the sensor in the existing Homag bracket, so you keep the original mounting point and do not drill a new hole.
• Body length choice — The body comes in 25 mm or 30 mm, so measure the old sensor to pick the length that clears the bracket and reaches the target.
• Switching gap — A sensing distance of 0.8 mm sets how close the target must run, so check the gap with a feeler before you lock the sensor down.
• Output behaviour — The normally open output closes only when a target is within the sensing distance, which tells the control the part is present.
• Wear point at the face — The sensing face sits closest to the moving target, so inspect it for scuffing or metal chips whenever the machine faults on position.
• Installation by rotation — Turning the M5x0.5 body sets the gap to the target, then the lock nut holds it, so setup is a thread adjustment, not a shim job.
• Spare stock decision — Keep the 4008610350 and 4-008-61-0350 number on the shelf label, so the right sensor is pulled when a station stops.

What changes on the shop floor when the right part goes back in:

• Fits the bracket you already have. The M5x0.5 thread matches the Homag mounting point, so a failed sensor comes out and the replacement goes in without drilling, tapping or adapting the bracket on the machine.
• Gap setting stays simple. With 0.8 mm sensing distance and a threaded body, you turn the sensor to the target and lock it, so setup is a repeatable thread adjustment rather than guesswork with shims.
• Correct signal to the control. A normally open output closes on target presence, so the control sees a clean present or absent signal instead of a doubtful reading that faults the cycle.
• Length matched to the job. Because the body comes in 25 mm or 30 mm, you can order the length that clears the bracket and still reaches the target, rather than forcing a body that sits too deep.
• Faster fault finding. When one station stops indexing, the 0.8 mm gap and the NO output give you two things to check first, so the machine is back in the cycle sooner.
• Fewer wrong-part orders. Quoting both 4008610350 and 4-008-61-0350 with the length on the enquiry means the sensor that arrives matches the one you pulled out.
