Toshiba obtains UL 508 certification for eight photorelays Toshiba Electronics Europe (“Toshiba”) has obtained approval to the industrial safety standard UL 508 and the UL product category NRNT for a total of eight photorelay products. The devices are also UL 1577 compliant and approved for use as industrial control switch and as solid state control devices for non-motor rated loads. Primary applications for these devices are industrial equipment (PLCs, I/O interface, sensor controls), building automation systems (heating, ventilation and air conditioning [HVAC]) and the replacement of mechanical relays in AC24 to 400V and DC24 to 125V systems. The eight photorelays are TLP172GM, TLP176AM and TLP3122A in a 4pin SO6 surface mount package with continuous current handling up to 1.4A (4.2A pulsed). The other five products TLP240A, TLP240D, TLP240G, TLP240GA, and TLP240J are in a DIP4 package with current capability up to 0.5A continuous or 1.5A pulsed and they also include a surface mount option. The photorelays can be used in industrial control equipment that is marketed worldwide, allowing them to be used in a wide variety of use cases. By using Toshiba’s UL 508 approved products, designers will find obtaining approval for their equipment much easier. The UL508 standard defines requirements for some parts in detail, including Solid State Relays (SSR). The temperature restriction for plastics (epoxy) restricts the temperature for resin within an SSR to 105°C. SSRs may only be operated at temperatures up to this upper limit. Using Toshiba’s UL certified products ensures that equipment is capable of complying with the relevant UL standard as well as ensuring the thermal design margin for SSRs is maintained.

R&S AREG100A automotive radar echo generator – the reliable and future-proof production tester for automotive radar sensors As essential components for autonomous driving, radar sensors help keep road users safe. With each stage on the way to fully autonomous driving, the number of radar sensors per vehicle rises significantly. Both OEMs and Tier 1 suppliers need reliable test solutions, suitable for mass production, for the large number of safety-related radar-based driver assistance systems. Rohde & Schwarz developed the new R&S AREG100A automotive radar echo generator in close cooperation with the automotive industry. The T&M expert put its decades of experience in millimeterwave technology into designing a test and measurement product precisely tailored to the automotive industry’s test requirements. Rohde & Schwarz developed the new R&S AREG100A automotive radar echo generator in close cooperation with the automotive industry, specifically for final test and inspection on OEM and Tier 1 production lines. Continuous quality control in production is essential to ensure the unrestricted functionality of radar sensors, and ultimately safe autonomous driving. The R&S AREG100A is a customized solution for use at the end of the production line. It fulfills all requirements for reliable operation and is easy to operate. The R&S AREG100A automotive radar echo generator reliably tests radar sensors in the 24 GHz ISM band and in the E band at 77 GHz or 79 GHz. It simulates echoes of up to four artificial target objects at fixed distances. User- configurable Doppler offsets can optionally be applied to simulate radial movement of the objects. Customers can specify desired fixed distances at the time of order. The R&S AREG100A is a future-proof solution for testing advanced long-range and short-range radars. It supports bandwidths up to 4 GHz in the E band and can simulate objects at a minimum distance of 4 m if the distance between the frontend and the DUT is 80 cm. With this approach, Rohde & Schwarz offers its customers an extraordinary degree of test flexibility, from simple to complex. Due to the dramatic rise in the number of vehicles equipped with radar-based safety-related driver assistance systems, the European regulatory authorities have stipulated mandatory tests in the Radio Equipment Directive (RED) to ensure safe operation and coexistence of automotive radar sensors, particularly with respect to autonomous driving. For easy, convenient and cost-optimized execution
