Chapter 1: Introduction Overview
Retail stores, supermarkets, restaurants, banks, ticket machines, and self-service terminals commonly use point of sale (POS) systems. Among other components, receipt printers incorporated into such equipment require highly reliable cutting mechanisms that allow quick and clean separation of paper at the end of each transaction. The core component of such receipt printers is the solenoid-driven receipt cutter.
It is necessary to use a compact actuator in the high-speed receipt cutter to ensure rapid actuation, accuracy of position, long lifetime, and constant cutting force. The open-frame solenoid is a popular solution for various POS receipt cutter applications due to its simple construction, high response speed, efficient electromagnetic performance, and flexibility of customization.
Compared with traditional sealed solenoids, open-frame solenoids offer improved heat dissipation, light weight, and better integration with automated printing mechanisms. Understanding of design peculiarities, performance parameters, and customization possibilities of open-frame solenoids is very useful for POS equipment manufacturers looking for motion control components.
Chapter 2: What is an Open Frame Solenoid for POS Receipt Cutters?
The open frame solenoid is the electromagnetic actuator consisting of the coil, metal frame, plunger, return spring, and some parts of the magnetic circuit. When the coil is energized by electrical current, the magnetic field is created. The magnetic field attracts or repels the plunger and creates the linear mechanical motion.
The solenoid in POS receipt cutters transforms the electrical energy from the control board of the printer into mechanical energy. This mechanical energy triggers the cutting blade assembly, and the printer can cut the receipt paper fast.
The open frame means that the electromagnetic parts are partly exposed and not enclosed in the tubular casing. The main advantages of this design are
- Improved heat dissipation during continuous operation;
- Lightweight construction;
- Lower manufacturing costs;
- Adjustable stroke and force requirements;
- Easy integration with mechanical assemblies.
The POS printer must operate reliably during repeated high-speed operation, as it performs thousands or millions of cutting operations over its lifetime.
Chapter 3: How Does the Open Frame Solenoid Work in POS Receipt Cutters?
The working principle of the POS receipt cutter solenoid is based on the generation of electromagnetic force.
Once the transaction is completed in the point of sale system, the printer controller sends the short electrical pulse to the solenoid coil. When the coil is energized, it generates the magnetic field, which attracts the iron plunger to the center of the magnetic circuit.
There is a mechanical linkage between the plunger motion and the cutter blade assembly. The rapid linear motion pushes the blade in the forward direction, and the blade cuts the receipt paper.
After the end of the electrical pulse, the return spring returns the plunger to its initial position, ready for the next operation.
The full cycle of operation includes the following steps:
- Control system electricity activation
- Generation of magnetic force in the coil
- Fast plunge action
- Mechanical blade actuator
- Spring back and reset
The solenoid should have an optimal magnetic design, low moving mass, and tight tolerances to provide rapid response time for high-speed POS applications.
Chapter 4: POS Receipt Key Requirements for Solenoid Cutter

Depending on application conditions, many industrial-grade solenoids have to provide more than 100,000 operating cycles.
4.3. Compact size and lightweight construction
“POS printers are becoming smaller and smaller, in particular portable receipt printers and mobile payment terminals.”
The open-frame solenoid design reduces the installation space since:
- The structure is thinner than most of the enclosed actuators
- The mounting bracket can be customized
- The magnetic frame can be optimized for particular applications
4.4. Optimization of cutting force
The receipt cutter has to provide sufficient force to cut different types of paper without damaging the mechanism.
The solenoid force depends on the following factors:

This advantage makes open-frame solenoids suitable for high-volume POS equipment manufacturing.
Chapter 7: High-Speed Receipt Design Considerations for Cutting Solenoids
Optimization of magnetic circuits
The performance of the solenoid is directly dependent on the magnetic circuit. Engineers have to optimize the following elements:
- Material of the iron core
- Design of pole
