olex has introduced one of the industry’s first ODVA


conformance tested and approved IP67 EtherNet/IP I/O module to interface with roller drives. The


Featuring an IP67-rated housing, the HarshIO


modules provide protection a


against the ingress of dust


and liquid in high vibration environments. Machine mounting saves on cabinet space and reduces wiring costs in the field. An integrated two-port switch with


roller drives directly, even in t


the toughest environments. I


Interfacing with up to four r


100Mbps delivers full duplex data transmission and enables a daisy- chain wiring topology for additional cost-savings. The company’s Ultra- Lock push-to-lock connection system delivers further time saving benefits for reliable IP67-sealed connection of cordsets during commissioning. The HarshIO module supports


eight digital inputs, four digital outputs and four analogue outputs controlling the speed of the drive. Featuring built-in protection to help prevent short circuit and current overload events, the modules also come equipped with diagnostic LEDs for visual feedback on network, power and I/O status. www.molex.com

ROTARY CODED SWITCHES FOR TWO WAY RADIOS AND PORTABLE APPLIANCES


The Elma C15 Rotary Coded Switch range is now available from Foremost Electronics. The C15 multifunction switch is intended for cost s


T n


sensitive applications where space is critical and is particularly suitable for frequency and c


channel selection in two way radios, portable appliances, instrumentation and similar miniaturised mobile applications. This device is claimed by the company to offer a r


remarkable switching “feel” and provides a r


reliable HMI device, delivering consistent t


torque over its long life time. Key features include a body size just 7.7 by 9.35 by 11.1mm, operating lifetime of 15,000 switching cycles,


operating temperature range from -30 to 60°C, 16 positions gray coding, shorting switching mode, up to 3.0Ncm switching torque, tray or tape and reel packaging and THT suitable for reflow soldering. Users can specify custom shaft dimensions and shape. The C15 rotary coded switch has switching options of 16 positions with 20° indexing and end-stop or 16 positions with 22.5° indexing with endless rotating shaft. Alan Cook, Managing Director of Foremost Electronics, says: “Elma is a long established manufacturer of


high quality switching products. Their new miniature rotary encoder is a very flexible and reliable control device for handheld and portable devices and will find many commercial and industrial applications.” www.enclosures4u.com


Specialist distributor JPR Electronics are major stockists of Hongfa miniature PCB and power relays. Hongfa is barely more than thirty years old yet produce over a billion relays each year from largely-automated factories. They have become one of the go-to companies when relays are needed for industrial or domestic appliance control, telecommunication, automotive and security applications, with around 160 different series of relays and nearly 40,000 specific items available to cater to each of these markets. The availability of form-fit-and-function


alternatives to widely used industry standard relays gives designers’ access to lower cost and more efficient products from Hongfa making them a suitable alternative to other manufacturers in more known brands while reducing bill of material costs. www.jprelec.co.uk


Omron Electronic Components Europe has launched a tiny MOSFET relay that has a footprint of just 2.9mm2 but is capable of handling 1.5A. The S-VSON device has overall dimensions of 2.0mm x 1.65mm x 1.45mm achieved using a 3-stack chip on chip structure. The G3VM-31QR offers on- resistance of just 0.10Ohms. Despite its small size, it can handle a continuous load current of 1.5A at 30V AC or DC and offers a wide temperature range of -40 to 110 0


dielectric strength of 500V between input and output is exceptional for such a tiny device.

CN-L HIGH-CURRENT LATCHING RELAY FOR AUTOMOTIVE APPLICATIONS


relay can be used to disconnect the battery to cut the power off in case of a short circuit, as a main relay for Li-ion battery protection or as a switch for dual power supply. It has been designed especially for automotive applications and features a high shock and vibration resistance. Modern vehicle topologies


increasingly use dual battery systems to support features like

sailing mode or fast recuperation. In order to protect such dual battery systems, latching-type relays are a highly interesting solution, especially


considering the power consumption. The CN-L relay is a reliable solution for 12V battery systems. As electromechanical relays can handle high currents, short-time overloads and offer galvanic isolation they are cut out to perform these tasks and offer additional safety in the event of a crash or fire. This relay is designed for a continuous current of 150A and an overload of 1500A for 0.5 seconds. This makes it universally suitable for different on-board electrical system topologies and applications. The relay weight is approx. 150g and can be integrated directly under the hood because of its closed design.
