Tab Verifier
IS240
Double Shell and Missing Tab Detector
The Innosen IS240 Tab Verifier is a compact inspection system for detecting double shells and missing tabs on end conversion presses.
Designed for fast installation, quick calibration, and minimal downtime, the IS240 helps end makers protect production reliability, identify press faults quickly, and prevent incomplete tabbed ends from continuing downstream.
At a Glance:

- Compact sensor design for easier mounting in tight press spaces
- Quick calibration after maintenance stops
- No recalibration needed after cable changes
- Modular controller supports up to four lanes
- Suitable for line speeds up to 1000 shells/min
- Fast response time of 2 milliseconds or better
COMMON QUESTIONS
Are double shells causing press problems?
Double shells entering the conversion press can cause costly interruptions and increase the risk of tooling damage. The Innosen IS240 Tab Verifier helps detect double shells before they create bigger production problems.
By checking ends directly on the conversion press, the IS240 gives operators a faster way to identify faults and respond before downtime increases.
Are missing tabs reaching downstream production?
A missing tab can turn a converted end into an incomplete product. If it is not detected on the press, it may continue downstream and create quality complaints, sorting work, or rejected production.
The IS240 detects missing tabs during end production, helping end makers stop incomplete tabbed ends before they move further into the process.
Can one system support several lanes?
Yes. The IS240 is a modular system that can support up to four lanes with one controller. It can be supplied for 1, 2, 3, or 4 lane presses, depending on the press configuration.
Can the system fit into limited press space?
Space around a conversion press is often limited. The IS240 uses compact sensors with a short and narrow casing, making them easier to mount in the available press area.
The system is designed for practical installation on typical end conversion presses, with sensors placed at the infeed and outfeed of each lane. The PDS specifies that transmitter sensors are fitted above the conveyor belt and receiver sensors below
Will operators need to recalibrate often?
The IS240 is designed to reduce recalibration work. It works with aluminium and steel ends/tabs without adjustment, and cable changes do not require recalibration because the cables are not part of the sensing circuit.
For maintenance stops, the system includes local and global recalibration inputs, allowing calibration to be restarted for one selected sensor or for the full system.
How does the IS240 help reduce downtime?
The IS240 helps reduce downtime by combining fast detection, quick calibration, clear visual status signals, and modular controller cards.
The controller provides visual indications for good objects, bad objects, calibration, and error states. It also performs continuous error checks, and activates a warning output if a system fault is found.

Frequently Asked Questions
What is the IS240 Tab Verifier?
- The IS240 Tab Verifier is a compact inspection system for detecting double shells and missing tabs on end conversion presses.
What defects does the IS240 Tab Verifier detect?
- The IS240 detects double shells and missing tabs during end production. This helps reduce production interruptions and prevents incomplete tabbed ends from continuing downstream.
Where is the IS240 installed?
- The IS240 is installed on the conversion press. For each lane, sensors are fitted at the infeed and outfeed of the press.
How are the IS240 sensors arranged?
- For each lane, transmitter sensors are installed above the conveyor belt, while receiver sensors are installed below. Shells should pass approximately 5 mm above the receiver sensors.
Can the IS240 work with aluminium and steel ends?
- Yes. The IS240 works with aluminium and steel ends/tabs without adjustment.
How many lanes can one IS240 controller support?
- One modular IS240 controller can support up to four lanes. The system can be supplied for 1, 2, 3, or 4 lane presses.
Does the IS240 need recalibration after a cable change?
- No. The IS240 does not require recalibration after a cable change because the cables do not form part of the sensing circuit.
How fast is the IS240 Tab Verifier?
- The IS240 has a response time of 2 milliseconds or better and is suitable for line speeds up to 1000 shells/min.
What makes the IS240 easy to install?
- The IS240 uses compact sensors with a short and narrow casing, making them easier to fit into the limited space around typical conversion presses.
What happens if the IS240 detects a system fault?
- The IS240 performs continuous error checks. If a system fault is found, the warning output is activated so operators can respond quickly.
