Omron launches super-sensitive non-contact temperature sensor

28 JUNE 2017

Omron Electronic Components has extended its non-contact MEMS thermal sensor range with a new narrow-field version specifically designed to provide accurate non-contact measurements of an objects’ surface temperature for industrial control, medical and building automation systems. Omron is relaunching its full range of MEMS thermal sensors in Europe, including wider field versions ideal for detecting room occupancy and similar applications.
The new Omron D6T-1A-02 is a super-sensitive infra-red (IR) temperature sensor that makes full use of proprietary Omron MEMS sensing technology. It can measure the surface temperature of an object between -40 up to +80°C in the target area with an accuracy of +/-1.5°C and a resolution of 0.06°C. The device includes a state-of-the-art MEMS thermopile, a sensor ASIC (Application Specific Integrated Circuit) and a signal processing microprocessor in a tiny package of only 12.0mm x 11.6mm x 9.2mm. The D6T-1A-02 features a narrow field of view of 26.5 degrees square, allowing it to accurately assess the surface temperature of a specific object in this area. Features also include a digital I2C output which offers excellent noise immunity (measured as noise equivalent temperature difference) of 140mK.
The Omron D6T thermal sensor is also ideal for building automation applications, measuring the temperature in a room, or detecting occupancy even when people are stationary. For these applications, Omron is offering versions with a wider field of view. These include a 1×1 device, the D6T-1A-01, with a field 58 degrees square. A 4×4 version and a 1×8 version are also available. These ultra-sensitive sensors are an outstanding alternative to pyroelectric sensors or PIR detectors in home automation, building automation, healthcare, security and industrial applications, which often fail to distinguish between an unoccupied space and a stationary person. The technology behind Omron’s D6T thermal sensors combines a MEMS micro-mirror structure for efficient IR radiation detection with a high-performance silicon lens to focus the infrared rays onto its thermopiles.
