PIZZATO NF B110BB-SMK Roller Plunger for HOMAG Holzma Weeke Machine 4008320259

Product Description

The PIZZATO NF B110BB-SMK is a modular prewired roller plunger limit switch for HOMAG Holzma Weeke machines, carrying Homag part numbers 4-008-32-0259 and 4008320259. It has a technopolymer housing with 20 mm fixing points. To confirm fit, check your machine's parts manual for those Homag numbers and compare the 20 mm fixing points and M12 connector position on the old switch.

When the roller plunger on a Homag Holzma Weeke machine stops triggering reliably, the machine may fail to index, clamp, or complete its cycle. This switch is the drop-in replacement for that failure point. It is a modular prewired limit switch with a roller plunger, built for Homag machine spare parts use.

The NF B110BB-SMK uses a technopolymer housing with 20 mm fixing points. It is an original, new switch. It fits Homag Holzma Weeke machines where Homag part number 4-008-32-0259 or 4008320259 is called for. To confirm the fit, match those numbers in your machine manual and check the 20 mm fixing points and M12 connector location against the switch you are replacing.

Mounting is straightforward: the 20 mm fixing points align with the existing holes, and the M12 connector enters from the bottom. That bottom entry keeps the cable run tidy and avoids strain at the plug.

Supply is for woodworking machine spares, including Biesse, Homag, SCM, CNC tooling, edgebander, and CNC panel beam saw parts. No packing or customisation details are stated. When you enquire, send the Homag part number 4-008-32-0259 or 4008320259, the machine model, and a photo of the old switch showing the 20 mm fixing points and M12 connector.

Product Features

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

• Roller plunger actuation — The roller plunger design lets the switch trigger as a moving machine part passes over it, suiting repetitive Homag Holzma Weeke cycles.
• 20 mm fixing points — Two 20 mm fixing points in the technopolymer housing line up with the existing mounting holes on the machine bracket.
• Technopolymer housing — The technopolymer housing holds the switch body and the 20 mm fixing points, giving a stable mount on the machine frame.
• Bottom-entry M12 connector — The M12 connector enters from the bottom of the switch, keeping the cable run low and away from the roller plunger path.
• Homag part number match — Homag part numbers 4-008-32-0259 and 4008320259 identify this switch for Homag Holzma Weeke spare parts ordering.
• Original new condition — Supplied as an original, new switch, so the roller plunger and housing arrive ready to mount on the machine.
• Roller check before mounting — Before you tighten the 20 mm fixing points, check that the roller plunger rolls freely and returns to its rest position.
• M12 connector alignment — With the M12 connector entering from the bottom, route the cable so the plug seats fully and does not pull on the housing.

Product Advantages

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

• Replaces the worn trigger point directly. When the roller plunger no longer trips the circuit, this switch gives you the same Homag part number 4-008-32-0259 to order, so you avoid adapting a different switch to the bracket.
• Mounts on the existing 20 mm pattern. The 20 mm fixing points match the bracket holes, so you bolt the switch down without drilling new holes. That keeps the machine frame untouched and the switch position repeatable.
• Keeps the cable entry low. The M12 connector enters from the bottom, so the cable drops away from the roller plunger. That reduces the chance of the plug being knocked or strained during machine cycles.
• Housing stands up to the shop floor. A technopolymer housing with 20 mm fixing points gives a solid base for the switch body. It holds the roller plunger in line with the moving part so the trigger point stays consistent.
• Order by the numbers on the old switch. The Homag part numbers 4-008-32-0259 and 4008320259 let you match the switch to the machine manual before you order, cutting the chance of a wrong part on the bench.

Frequently Asked Questions

Which machines does this switch fit?

It fits Homag Holzma Weeke machines that call for Homag part number 4-008-32-0259 or 4008320259. Check your machine's parts manual for those numbers and compare the 20 mm fixing points and M12 connector with the old switch.

How do I confirm the fit before ordering?

Match the Homag part number on the old switch or in the manual to 4-008-32-0259 or 4008320259. Then check the 20 mm fixing points and the bottom-entry M12 connector against the switch you are removing.

What is the fixing point spacing?

The housing has 20 mm fixing points. Measure the hole spacing on your bracket and compare it to 20 mm before you order, since the switch mounts on that pattern.

What connector does it use?

It uses an M12 connector that enters from the bottom of the switch. Route the cable so the plug seats fully and the cable does not pull on the housing during machine movement.

Is the roller plunger replaceable on its own?

Only the complete switch is described here, as an original, new unit with a roller plunger. No separate roller plunger part is stated, so plan to fit the complete switch.

What should I check before mounting it?

Check that the roller plunger rolls freely and returns to rest, and that the 20 mm fixing points line up with the bracket holes. Also confirm the M12 connector enters from the bottom as on the old switch.

What do I need to send with my enquiry?

Send the Homag part number 4-008-32-0259 or 4008320259, your machine model, and a photo of the old switch showing the 20 mm fixing points and M12 connector. That lets the supplier check the switch against your machine.

Do you supply other woodworking machine spares?

Yes. The range covers Biesse machine parts, Homag machine parts, SCM machine parts, CNC woodworking tools, edgebander machine parts, and CNC panel beam saw parts, so you can ask about several machines in one enquiry.
