HC Relays Miniature Relay Datasheet by Matsushita Electric Works

Category: Electronics, Panasonic, Relays

Overview

The datasheet details the HC Relays series, which are miniature relays designed by Matsushita Electric Works (now known as Panasonic Corporation) for broad applications. These relays are available in various contact arrangements, with options ranging from 1 Form C to 4 Form C, and are capable of handling loads from low levels (100µA) to high levels (10A). Special features include extended mechanical operational life—minimum of 10^8 mechanical operations for the DC type—and availability in both standard and amber sealed types. Bifurcated contact types are designated as HCAD.

Specifications

Relays in the HC series offer diverse configurations, with contact ratings up to 10A at 250V AC and maximum switching voltages and powers rated up to 2,500VA. The electrical life expectancy of these relays varies, reaching up to 10^8 operations for certain models under specific conditions (24 V DC with resistive load). Mechanical life extends up to 10^8 operations at 180 cycles per minute (cpm).

Relay Characteristics

The HC Relays maintain impressive performance metrics, including a maximum operational speed of 20 cpm at peak rating, high insulation resistance (minimum 1,000 MΩ at 500 V DC), and predefined breaking capacitances across their contacts. They offer quick operation times (maximum 20ms) and release times without exceeding a temperature rise of more than 80 degrees Celsius at nominal voltage. The relays are also defined by robust shock resistance for both functional (minimum 196 m/s²) and destructive (minimum 980 m/s²) impacts. Suitable vibration resistance is also guaranteed, ensuring reliable performance under physical stress.

Environmental Conditions and Life Expectancy

Operational temperatures for the HC Relays range from -55°C to +70°C, with a humidity tolerance of 5 to 85% RH, encompassing conditions for operation, transit, and storage. Each relay unit weighs approximately 30g.

Typical Applications

These relays are versatile and can be used in a variety of sectors, from transportation to amusement devices, power station and building control systems, medical and office equipment, and refrigeration, demonstrating their suitability for diverse industrial and commercial uses.

Ordering Information

The datasheet also outlines the ordering process for relays within the HC series, providing a clear guide on selecting the appropriate contact arrangements, terminal types, coil voltages, and optional features such as bifurcated contacts or LED indicators.

Coil data for both AC and DC types are meticulously defined, with information on allowable voltages, nominal currents, and recommendations for maintaining optimal operational performance.

It’s important to take into account that specifications may vary depending on foreign standards and certifications. It is also recommended to verify compatibility with specific loads and conditions to ensure reliable performance.
