Omron Electronics Components Europe has released two new fully sealed, miniature micro switches providing a particularly compact and flexible solution for applications exposed to water spray or high dust levels. The D2GW and D2AW are excellent for vending machines, smart meters, security systems, HVAC equipment, EV charging stations, white goods and similar applications where space is at a premium.
The new D2GW is fully sealed to IP67 and can function in temperatures of up to 85C. It is set apart by its particularly small size (8.3mm x 6.5mm x 5.3mm) and is possibly the smallest switch of its type in the industry. The company is providing the switch in various styles, with a selection of mounting structures, actuators and terminal specifications to maximise application flexibility. The options incorporate press-fit terminals to facilitate solder-less PCB installation, as well as solder terminals, PCB terminals and moulded wire leads. The device offers a symmetrical shape with the push button located in the centre, enabling levers to be added in either direction.
The company has also released a new version of its standard basic switch; the D2AW also sealed to IP67. This switch offers compact dimensions (13.3mm x 7mm x 5.3mm) and high insulation resistance of 100MOhm. A version of the switch, designated as D2AW-R, provides an integrated internal resistor enabling the detection of four states: on, off, open circuit and short circuit. The switches are offered with solder terminals, spade terminals and moulded wire leads.
Both devices offer a unique contact design to maximise performance. A sliding contact construction delivers quiet operation and high contact reliability, wiping away any dust or other impurities. They also have double contacts to improve reliability.
