Switching heavy loads
27 July 2010
With almost 2000 permutations in its range, Panasonic offers relays for a host of applications.
Indeed, there are seven series of relays with the prefix H, so drawing from this pool of relays there is a capability of switching from the low level of 100mA up to 35Amp, dependant upon which series option is chosen.
Even though these relays are designed for switching heavier loads, they are all cadmium-free and RoHs compliant.
The company offers two slim-line ranges; the HJ, which switches up to 10A/25VAC on the 2C and 5A/250VAC on the 4C, plus the HN with an added switching capability of 16Amp/250VAC on a 1A contact.
The HC range can switch 10A/250VAC with a 1C, 7A/250VAC with the 2C/3C, and 5A/250VAC with four contact sets. An IP67 sealed version with a maximum switch of 5Amps is included in the HC range, together with a magnetic latching type with a nominal switch of 3A/250VDC. However, the HP, HL and HG ranges graduate from a 10A/250VAC switch up to 20A/250VAC switching with between 1C and 4C contact sets.
Finally, the largest series, the HE, has a 35A switch capability and a contact gap of 3mm on the 1A version, and a maximum TV-15 rating; 10KV high dielectric surge and an insulation gap of 8mm.
There are a variety of mounting methods available, from PCB mount, solder terminals, and top mounting, plus all these ranges come with an array of socket types.
