ASMA21 is a terminal blocks and din rail product line by Phoenix Contact. It was developed to meet the needs of industrial automation, telecommunications, and instrumentation applications in applications with signal currents up to 17 amperes, and is suited for global usage. It provides reliable and cost-effective solutions for secure connections that meet the highest performance requirements.

ASMA21 terminal blocks and din rail products feature heavy-duty plastic housing for strength and durability, fully-isolated design with reinforced insulation for maximum current carrying capacity, and special terminal protection that eliminates costly repairs and modifications. With an integrated multi-polar or spring-type terminal, they offer excellent shock and vibration protection for reliable operation and rapid disconnection and wiring. They are designed with low clamping force for easy assembly and quick wiring.

ASMA21 terminal blocks and din rail products are suitable for a variety of applications, from point source and distributed connection systems to main and service distribution boards. They are also suitable for electrical and electronic systems with high current carrying capacity, including industrial control, communications, data processing, and instrumentation equipment.

The main feature of ASMA21 terminal blocks and din rail products is the use of a flexible, low voltage, low current, contactless electrical connection system. This connection system allows easy, fast, and reliable connections of the terminals into data communication lines, and ensures reliable connections with low contact resistance. This connection system helps to reduce time and cost associated with wiring and assembly, as well as eliminates any issues associated with improper wiring.

The working principle of ASMA21 terminal blocks and din rail products is based on a two-part, “contacting” connection. The first part is the “push-in”, which consists of a push-in female contact element and a push-in male contact element connected using a common thread. The second part is the “plug-in”, which is a plastic socket fitted to the contact element and a spring terminal connected to the male contact element. When the connection is made, an electrical connection is formed through the metal contact element, and the plastic socket ensures that the electrical connection is reached at the tip of the male contact.

The advantages of ASMA21 terminal blocks and din rail products are numerous. In addition to their flexibility and fast installation, they provide reliable performance, provide a high temperature range, and are rated up to IP 68 (waterproof and dust proof). They also offer a wide variety of sizes and configurations, and can be easily integrated with other components. In addition, the spring terminals require minimal force to make a connection and are especially suitable for use in vibration-prone applications.

ASMA21 terminal blocks and din rail products are ideal for a wide range of applications, including cable bundles, machines, and industrial enclosures; control cabinets, data acquisition and control systems; and instrumentation, lighting, and communication systems. They are built for reliable performance and are suitable for use in a wide range of industrial environments, including harsh, wet, and ambient settings.
