YAMAHA ZS KLJ-MC400-011 24mm Electronic Feeder for YSM20R

YAMAHA ZS KLJ-MC400-011 24mm Electronic Feeder for YSM20R

The YAMAHA ZS KLJ-MC400-011 24mm Electronic Feeder is designed to supply components packaged in 24mm embossed carrier tape to compatible SMT placement equipment. It provides controlled tape advancement so that each component pocket is accurately positioned at the pickup point for the placement head.

The KLJ-MC400 family is identified in YAMAHA technical documentation as the ZS FEEDER ASSY. 24MM series. The documented feeder dimensions are approximately 507mm × 228mm × 31.5mm, with a weight of approximately 1.47kg. It supports 24mm embossed carrier tape with a maximum tape thickness of 0.6mm and feed-pitch settings from 2mm to 32mm.

For electronics manufacturers operating mixed-component SMT lines, a correctly selected feeder helps maintain consistent tape positioning, stable component pickup and efficient production changeovers.

Cause

Feeder-related production problems are often caused by mechanical wear, incorrect tape specifications, contamination, damaged tape guides or unsuitable feeder selection.

A feeder that does not advance carrier tape consistently may cause the component pocket to arrive outside the intended pickup position. This can contribute to pickup errors, component loss, machine stoppages or repeated operator intervention.

Incorrect feeder width is another common problem. A feeder designed for 24mm carrier tape should be matched with the correct tape width and reel configuration rather than substituted with an incompatible feeder.

Wear in the tape transport mechanism can also affect repeatability after extended production use. Regular inspection of the feeder body, tape path and moving sections is therefore important for maintaining consistent operation.

Solution

The KLJ-MC400-011 ZS 24mm feeder provides a dedicated feeding solution for components supplied in 24mm embossed carrier tape.

Its electronic feeding mechanism advances the tape according to the pitch configured for the component package. The feeder presents successive component pockets at the machine pickup position, allowing the placement head to remove components during automated production.

The feeder supports a broad range of tape pitches, making it suitable for different component package lengths while maintaining the same 24mm carrier tape width.

Using the correct feeder series can help users achieve more stable material handling, reduce unnecessary tape-position adjustments and improve feeder preparation efficiency during line setup.

Specifications

The dimensional, tape and feed-pitch specifications above are listed for the KLJ-MC400-00X 24mm ZS feeder family in the YSM20R reference documentation.

ZS Feeder Series Comparison

YAMAHA reference information identifies KLJ-MC400 as the 24mm ZS feeder family and lists progressively wider KLJ feeder families for 32mm, 44mm, 56mm and 72mm carrier tapes.

Application

The YAMAHA ZS KLJ-MC400-011 feeder is intended for automated SMT production where electronic components are supplied in 24mm embossed carrier tape.

It can be used for components whose package dimensions require a wider carrier format than standard 8mm, 12mm or 16mm tape. Typical applications may include larger integrated circuits, connectors, modules and other components packaged in compatible 24mm embossed tape.

The feeder is particularly useful in production environments requiring frequent model changes because the available pitch settings accommodate different pocket spacings without changing to another feeder width.

It is suitable for use in electronics manufacturing sectors such as industrial electronics, automotive electronics, communication equipment, consumer electronics, power-control products and other PCB assembly operations.

How It Works

The feeder holds the component reel and guides the 24mm carrier tape through the tape transport path.

During production, the electronic drive mechanism advances the tape by the programmed pitch. Each movement brings the next component pocket into the pickup position.

The placement machine then removes the exposed component from the carrier pocket using the appropriate nozzle. After pickup, the feeder advances the tape again according to the programmed component pitch.

For the KLJ-MC400-00X 24mm feeder family, YAMAHA documentation lists feed-pitch selections of 2mm, 4mm, 8mm, 12mm, 16mm, 20mm, 24mm, 28mm and 32mm.

This range allows one feeder width to handle various 24mm carrier-tape component formats.

How To Choose

First confirm the feeder part number on the existing feeder label. For this product, the target number is KLJ-MC400-011.

Next confirm that the carrier tape is 24mm wide. Feeder width should always correspond to the tape format used for the component.

Check the tape material and pocket design. The documented KLJ-MC400-00X specification is intended for embossed carrier tape with a maximum thickness of 0.6mm.

The component feed pitch should also be confirmed. This feeder family supports multiple pitch settings from 2mm through 32mm, but the actual required setting depends on the component packaging.

Finally, confirm the machine model and feeder interface before ordering. A photo of the existing feeder label, machine model and component reel information can significantly reduce the risk of selecting an incorrect feeder revision.

Why Choose the KLJ-MC400-011

The main advantage of this feeder is its dedicated 24mm tape format combined with multiple feed-pitch options.

Instead of adapting a narrower feeder to unsuitable tape, operators can use the correct feeder width for stable tape guidance. This is particularly important when components are packaged in larger embossed pockets where tape alignment directly affects the pickup position.

The KLJ-MC400-011 is also identifiable by a specific YAMAHA part number, which simplifies spare-feeder replacement and inventory management.

For factories maintaining several feeder widths, clearly separating KLJ-MC400 24mm units from other ZS feeder families can help reduce setup mistakes during production changeovers.

Maintenance Recommendations

Keep the carrier tape path clean and free from loose component debris, adhesive residue and dust.

Inspect the tape guide and transport mechanism when abnormal feeding, irregular indexing or repeated pickup errors appear.

Do not force carrier tape through the feeder if excessive resistance is detected. First confirm the reel installation, tape orientation and tape dimensions.

During storage, protect the feeder from impact, excessive humidity and contamination. Feeder handling should be performed carefully because tape-guiding and positioning sections require consistent mechanical alignment.

For replacement purchases, keep the old feeder label or clear photographs available so the part number and configuration can be compared before shipment.
