HC RELAYS MINIATURE RELAY FOR WIDER APPLICATIONS

Category: Electronics, Panasonic, Relays

Overview

The HC Relays datasheet presents technical details for Panasonic’s miniature relays engineered for diverse applications, boasting an exceptionally long lifespan and a range of configurations to suit various electrical requirements.

Features

Longevity: The relays are designed for endurance with a minimum of 10⁸ mechanical operations for the DC type.

Contact Arrangements: There are four contact arrangements available:

4 Form C (5 A 250 V AC)
3 Form C (7 A 250 V AC)
2 Form C (7 A 250 V AC)
1 Form C (10 A 250 V AC)

The relays can handle low to high-level loads ranging from 100 µA to 10 A, and hermetically sealed types are offered.

Versatility: Amber-sealed types and bifurcated contact types (as HCAD) are available for specialized environments and applications.

Specifications

The contact material used in HC Relays includes gold-flashed silver alloy and gold-clad silver nickel, optimizing both conductivity and durability. These materials, along with other construction elements, define the relays’ performance specifications:

Initial contact resistance maximum of 30 mΩ
Nominal switching capacities from 5 A to 10 A at 250 V AC
Maximum switching power from 1,250 VA to 2,500 VA
Minimum switching capacity of 1 mA at 1 V DC
Coil nominal operating power ranging from 0.9W to 1.3VA, depending on AC frequency or DC use

The specifications vary in accordance with different standards and certifications globally.

Characteristics

The relay characteristics emphasize operational durability and reliability:

Capable of up to 20 cycles per minute at maximum rating.
Initial insulation resistance is a minimum of 100 MΩ at 500 V DC.
Voltage breakdown benchmarks include 700 Vrms between contacts and 2000 Vrms between contact and coil.
The operate time is a maximum of 20 ms at nominal voltage with an equivalent release time without diode.
Temperature rise remains within tolerable limits, not exceeding 80°C at 70°C ambient temperature.

Environmental and Mechanical Durability

These relays are designed to resist the rigors of both operational and environmental stress:

Shock resistance is specified at a minimum of 196 m/s² for functional operations and 980 m/s² for destructive conditions.
Vibration resistance in operation has a double amplitude of 1.5 mm within a range of 10 to 55 Hz.
Relays operate within an ambient temperature range from -55°C to +70°C and can be stored between -55°C to +155°C.
Humidity tolerance is from 5 to 85% relative humidity.
Each unit weighs approximately 30g.

Life Expectancy

The relays’ expected life is contingent on usage conditions and varies from 1×10⁵ to 1×10⁸ mechanical operations, depending on voltage type and load (resistive or inductive), with the mechanical life reaching up to 10⁸ operations at 180 cycles per minute.
