A Special Purpose Relay is a relay designed for specific applications that require unique operating characteristics, such as high-speed switching, extreme environmental resistance, or custom contact configurations. These relays are used in industries like aerospace, medical, automotive, and telecommunications, where standard relays may not be suitable.
The 21 and 136 series flash transfer relays have a proven industry record of reliability. Their rugged design has allowed the products to be plugged in and left, for years of service. Recent changes in lighting techniques from incandescent to LED have prompted us to respond with a redesigned relay better suited for the low currents of LED lighting, but equally usable with tungsten lamps.
For HIGH VOLTAGE. Designed with a unique double make / break contact arrangement the 158 series is capable of switching loads up to 1kVA at 5,000 volts. An extra wide contact gap provides excellent arc resistance between contacts. The double break configuration ensures double gaps achieved at higher speeds than single break contacts to extinguish arcs.
The 102V series of reed relays are epoxy encapsulated for HIGH voltage. 102V is capable of 10mA at 5,000VDC. The 102HV is capable of 5mA at 10,000VDC. Typical use includes dielectric testers and medical equipment.
The 250 Series relay was designed as a replacement for the GE relays used widely in Control units for Gas Turbine power plants. They have the unique GE 14 pin plug design and also have LED and Neon indicator lamps with test push buttons for manual checking of operation. There are additional variations of this relay available as well.
