Relays & Optocouplers | Introduction

Reed relays use the reed switch as the heart of their switching mechanism. And as a result can switch billions of reliable operations (load dependent). Also they can switch up to 10,000 Volts and hold off up to 15,000 Volts. Furthermore, reed relays switch very low level signals as low as femtoamps and nanovolts. This is due to their environmentally or hermetically sealed contacts. Additionally they are very small and offer many unique switching abilities unlike semiconductor and electromechanical relays. These include stable low contact resistance <150 milli-ohms, low capacitance, high insulation resistance >10^14 Ohms, and carry currents up to 5 Amps continuous and 10 Amps pulsed. Reed relays operate in the 500 microsecond to 3 millisecond range and withstand shock up to 150G. We offer engineered relay solutions for a broad spectrum of product applications in all major markets. Check out our large assortment of package styles and pin-outs. Don't see what your looking for?

High Frequency

High frequency reed relays are capable of switching signals from DC up to 7 GHz. This is achieved by keeping the signal path as short as possible.  Additionally the relays use an internal coaxial shield with a consistent 50 Ohm impedance path. Not only is it excellent with RF signals, but is also great for digital signals where the skew rates or effects on the rise time of fast digital pulses is less than 40 picoseconds through the relay. Internal magnetic shield prevents any magnetic coupling effects between relays when designing a two dimensional or three dimensional relay matrix. These RF reed relays have a flat frequency response out to 20 GHz. Their cost is moderate and stable. Their size is becoming smaller and smaller.

Intrinsically Safe

Our intrinsically safe or ATEX approved reed relays & optocouplers are tested such that they will not become an ignition point.

Our optocoupler series are designed for these types of hazardous environments. Examples of hazardous locations include mining, chemical processing plants, refineries, power stations and high dust producing plants. As well as any potentially flammable atmospheres. Standards for intrinsically safe components are presented in EN500200. The required air and creepage paths as well as the electric strength are defined in detail as follows: The peak voltage cannot exceed 375 Volts in order to meet accepted worldwide standards. The sum of the input and output voltages must not be higher than 375 Volts Peak. The coil input has a voltage of 24 Volts max. and the contacts produce 230 VRMS or 325 volts peak output. Input plus output = 24 + 325 = 349 Volts peak. Here the safety margin for the voltage for the input and output meet their peak voltage limit of 375 volts. The air path for isolation of this voltage is 6mm and the creepage path is 10mm. The isolation inside the component through potting compounds is 2mm. Another important value is the Comparative Tracking index (CTI) value of plastic. In this case, the value must be greater than 175. The electric strength between the input and output is tested at 1500 VRMS or 2x the nominal voltage +1000.

Low Thermal

Low thermal reed relays can switch low voltages in the low microsecond (µV) range. And reed relays switch these low voltages without altering the signal level. Even after it has passed through the relay. Low thermal relays are used in transducers. Transducers that produce very low voltage signals and need to be both switched and amplified. Moreover high end multimeters use low thermal reed relays. And switching thermocouples in data acquisition systems. Temperature measuring, data logging and measurement applications all use low offset voltage relays. The BT/BTS series are an excellent choice over semiconductor relays. Request assistance for your low thermal design with our reed relay experts.
BT/BTS Reed Relay

Low thermal epoxy encapsulated BT/BTS Series Reed Relay capable of switching offset voltages <1µV with a 100% duty cycle. This extremely low thermal voltage is achieved through an optimized temperature balance between the reed switches and minimum coil power. An excellent choice over semiconductor devices.

Optocouplers

Optocouplers are intrinsically safe circuits that handle input/output isolation as high as 4,000 volts DC. Many of our optocouplers have met and been certified for the stringent requirements of ATEX and IECEx. Hence an optocoupler will not become an ignition point when subjected to short circuits or adjacent component failures. Furthermore they must also switch to a defined state when overloaded. Hazardous environments include any environment where an electrical arc could spark or ignite an explosion. Such as petrol-chemical, grain and medical processing plants. Additionally these optocoupler series offer long life due to non-abrasive mechanical wear and high reliability. And insulation resistance between input and output up to 10^13 ohms.
