AUTONICS-PR18-8DN Inductive Proximity Sensor Switch For Woodworking Machine

Product Description

The AUTONICS-PR18-8DN is an inductive proximity switch for woodworking machines, detecting metal targets without contact. It senses within 8mm, so you can confirm clearance to cams, bolts, or blades. The PR18-8DN body fits standard mounting brackets; check your machine's sensor mount and target distance before ordering. Buyers confirm fit by matching the model number and measuring the gap to the metal target. It is a spare for machines that use non-contact detection to trigger stops, guards, or feed controls.

When a limit switch on a woodworking machine wears out, the machine may stop indexing or fail to trigger a guard. The PR18-8DN replaces a contact-based approach switch with non-contact detection, removing the wear point that causes repeat failures. This matters on machines where metal cams or bolts pass the sensor many times per shift.

The AUTONICS-PR18-8DN is an inductive proximity switch, also called an approach sensor, for woodworking machine spares. It detects metal objects without physical contact, with a sensing range of 8mm. The model number PR18-8DN identifies the body and sensing face. To confirm fit, compare your existing sensor's model number and mounting thread, and check that the target passes within 8mm.

Mount the sensor so the metal target passes within the 8mm sensing range, and keep the face clear of chips and dust. Non-contact detection means no lever or roller to wear, so the switch does not change behavior as parts move. Check the gap with a feeler gauge or by jogging the machine before running production.

Supply is through DHL, FedEx, UPS, or other carriers. No customisation or packaging details are stated. When enquiring, send the machine make and model, the existing sensor's model number and photo, the mounting thread, and the target distance. That lets the supplier confirm the PR18-8DN matches your application before shipping.

Product Features

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

• Non-contact metal detection — The sensor detects metal targets without touching them, so there is no lever or roller to wear out.
• 8mm sensing range — A metal target passing within 8mm triggers the switch, giving you a fixed gap to set on the machine.
• AUTONICS model PR18-8DN — The model number PR18-8DN identifies the sensor body and sensing face for ordering the correct spare.
• Woodworking machine spare — This switch is a spare part for woodworking machines, replacing a worn approach switch on the machine.
• Inductive sensing principle — Inductive sensing responds only to metal, so wood chips and dust do not trigger false signals during cutting.
• High sensitivity — The sensor responds to metal targets within its 8mm range, helping maintain repeatable detection on fast cycling machines.
• Precision detection — Detection at a fixed 8mm gap supports consistent triggering where the machine needs a precise position signal.
• No contact wear point — Because nothing touches the target, the switch has no mechanical wear point to adjust or replace.
• Simple bracket mounting — The PR18-8DN mounts in a standard sensor bracket; check your machine's bracket and thread before ordering.

Product Advantages

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

• Fewer repeat failures. Non-contact detection removes the lever and roller that wear on mechanical switches, so the switch does not fail from repeated contact with metal targets.
• Stable trigger point. With an 8mm sensing range, the target gap stays fixed, so the machine triggers at the same position every cycle instead of drifting as parts wear.
• Chips do not trigger it. Inductive sensing responds to metal, not wood dust, so sawdust and chips passing the face do not cause false stops during production.
• Easy to confirm fit. The model number PR18-8DN and 8mm range give you two checks against your existing sensor before you order a replacement.
• Less maintenance time. No contact wear means no periodic adjustment of a lever or roller, freeing maintenance time for other machine checks.
• One spare covers the job. The PR18-8DN is a single switch for approach detection; keep one on the shelf for the machine that uses this model.
• Clear enquiry path. Send your machine model, existing sensor model, and target distance, and the supplier can confirm the PR18-8DN before shipping.
• It fits the machine you already run. The AUTONICS-PR18-8DN is made for Woodworking Machine, so it returns to the same shaft, bracket or spindle without re-machining the mounting.

Frequently Asked Questions

Will this sensor replace my existing approach switch?

Yes, if your existing switch is model PR18-8DN and your metal target passes within 8mm. Compare the model number on the old sensor and measure the gap before ordering.

Does it detect wood or only metal?

It detects metal only. Inductive proximity switches respond to metal targets, so wood chips and dust do not trigger the sensor during cutting.

What is the sensing distance?

The sensing range is 8mm. Set the gap between the sensor face and the metal target within that range, and check it with a feeler gauge or by jogging the machine.

How do I mount the PR18-8DN?

Mount it in a bracket so the sensing face points at the metal target and the gap is within 8mm. Check your machine's bracket and thread against the sensor body before fitting.

Can I use it on any woodworking machine?

It fits machines that use an 8mm inductive proximity switch and have a metal target passing the mounting point. Confirm the machine model and existing sensor model with the supplier.

What should I send with my enquiry?

Send the machine make and model, the existing sensor's model number and a photo, the mounting thread, and the target distance. That lets the supplier confirm the PR18-8DN matches your application.

How is it shipped?

Shipment is by DHL, FedEx, UPS, or other carriers. Ask the supplier for the shipping method and cost when you enquire.

Is the PR18-8DN a genuine AUTONICS part?

The brand is AUTONICS and the model is PR18-8DN. Ask the supplier to confirm the brand marking on the sensor before you order.
