80V 1.4A DIP photo relay includes protection
Toshiba has added over-temperature and over-voltage protection features to an 80V 1.4A photo-relay, all inside a 4pin DIP package. Called TLP241BP, it can switch ac or dc though its single isolate 280mΩ (max) output switch – implemented as a pair of back to back mosfets – and handle pulses up to 4.2A (100ms, 1/10 duty). Output leakage is 1μA max ...
Measuring temperatures on electric motor rotors
A compact wireless data acquisition system can investigate, monitor and optimise electric rotor motor operation, say Rolf Spellmeyer and Diego Llopis. In modern electric vehicles, different types of electric motors are available. Automobile manufacturers may select asynchronous or synchronous motors, and in some cases, they combine both motor types in one vehicle. In this context, synchronous motors are considered more ...
SM&E 2024: High-spec plastic components from the UK
Broanmain Plastics will be showing recent prototype-to-production projects at the Southern Manufacturing & Electronics exhibition in February. The company offers tool design and various plastic moulding and finishing technologies on a single site in Surrey. One of the projects was a motion sensor housing (right) for Cucumber Lighting Controls, which was seeking a UK-based moulder. “Manufacturing components on UK shores ...
Silicone form-in-place gasket seals automotive assemblies
Loctite has created a silicone form-in-place gasket material for automotive electronic enclosures. SI 5972FC is a one-part RTV (room temperature vulcanising) liquid-then-elastomer “with adhesion to a range of metal and plastic surfaces, specifically designed to pass OEM leak or blow-out pressure tests immediately after assembly”, according to the company. “By avoiding the need for curing ovens, Loctite SI 5972FC also ...
Pickering adds high voltage surface mount reed relays
Pickering Electronics, has announced its first high voltage surface mount reed relays known as the Series 219. Available in multiple package types (of the same size, but with differing pin positions), these reed relays can switch up to 1000V in 1 Form A (SPST), 2 Form A (DPST), and 1 Form B (SPNC) contact configurations; switch stand-off is up to ...
Ultrasonic micromachine puts bass into earbuds
XMems Labs has revealed a mems-based loudspeaker that uses ultrasonics to reproduce bass notes. Branded ‘Cypress’, the company describes it as “full-range” and said that it “achieves >140dB low frequency SPL [sound pressure level] enabling a no-compromise replacement for coil speakers in noise-cancelling earbuds”. In an earbud, there would be three parts: a conventional wireless earbud receiver IC, a custom ...
Productronica: high-voltage SMD reed relays
Pickering Electronics will introduce a series of surface-mount >1kV reed relays at Productronica in Munich next week. Series 219 reed relays “can effortlessly switch up to 1kV, and are the only surface mount high voltage relays available in the market in 2 Form A and 1 Form B packages”, according to the company. Some details are available now: stand-off is ...
Buzzers automatically make IEC 60601-1-8 medical alarm sounds
CUI Devices has announced a line of medical buzzers compliant with IEC 60601-1-8 alarm signal requirements. There are four CPIM-4410-80x buzzers, with a letter replacing the ‘x’ depending on function: C for the cardiovascular tone, T for the general tone, V for the ventilation tone and Y for the oxygen tone. Each has a stand-by (silent) mode and three alarm ...
600V opto-isolated mosfet is under 5mm long
After announcing 60V opto-mosfet relays last week, this week Panasonic has revealed a 600V type in a 2.65 x 4.45 x1.8mm package. AQY206GV’s 8Ω mosfet (15Ωmax) will switch 600V, and 150mA (450mA pulsed), with a maximum dissipation of 350mW. Its SSOP package is rated for 1,500Vrms isolation, and the whole device will work up to +105°C ambient. Maximuturn on and ...
