Product Overview

Needle Detector for Circular Knitting Machines (Item 6) is listed in our needle detectors group for circular knitting machine maintenance. Needle detector units, cables and holders that stop the machine when a broken or bent needle passes the sensor.

What This Part Does

A needle detector reads each needle as it passes a fixed point. A needle with a broken hook, a missing latch or a bent shank does not present the expected profile, and the machine is stopped before that needle drops a line of stitches down the whole roll.

Detectors are low voltage devices, commonly 6.3 V, 12 V or 24 V, and they are supplied with their own cables and holders because the sensing gap has to be held accurately.

Key Benefits

Stops a broken needle before it puts a running line down the fabric
Protects the sinkers and the cam box from a broken needle running on
Supplied with the cables and holders that set the sensing gap
Available for the common low voltage circuits

Application Scenarios

Single jersey and double jersey circular machines
Machines running fine gauge where a needle fault is hard to see
High speed machines where a fault costs many metres quickly

Who It Is For

Mills where a needle line fault means the whole roll is downgraded
Maintenance teams replacing failed detectors
Machine rebuilders restoring machine protection circuits

Problems It Solves

A running line down a full roll from one broken needle
Sinker and cam damage caused by a broken needle left in the cylinder
Detectors set at the wrong gap giving false stops or missing faults

Use Guide

Confirm the reference against the old part and the machine plate before ordering a full machine set.
Order one complete set per machine where the part is fitted in multiples, so wear is even across the fabric.
Clean the mounting position before fitting. Fly and old oil are the most common cause of a new part not seating.
Check the machine on a short run and measure the fabric before returning it to full production.
Record the reference against the machine so the next reorder does not have to be identified again.

Needle Detectors Questions

What voltage do I need?

Check the machine circuit before ordering. Detectors are made for specific low voltages and fitting the wrong one will either not work or shorten the life of the unit.

Why is the detector missing faults?

Most often the sensing gap has drifted or fly has built up on the sensor face. Clean it and reset the gap to the machine builder figure before replacing the unit.

Do I need one detector per machine?

That depends on machine size and how the machine was originally equipped. Send photos of the machine and we will confirm against what is fitted.
