TURCK's full line of 2-wire DC sensors now incorporate Uprox+ technology and quick-disconnect capabilities, making it the first of its kind to include Factor 1 technology. Beyond providing sensing distances that far exceed ferrite core sensors, these sensors provide simple and space saving mounting, compared to mechanical switches. Two-wire DC sensors are commonly used by machine engineers around the world.
"Equipping a 2-wire sensor with Factor 1 technology expands its usefulness for those companies exporting to countries that typically use these devices, like Japan," says Suchi Deshpande, product specialist with TURCK's sensor division. "These sensors are particularly relevant in the automotive industry for aluminum frames."
The Uprox+ technology provides extended sensing ranges for all metal types, and it features an integrated pre-damping protection function to reduce the metal free mounting area in applications. This allows traditionally flush mounted sensors to be recessed by half a turn for increased mechanical protection. Non-flush mounted sensors may be embedded in metal up to the outer edge of the thread on barrel style sensors and on all four sides of rectangular style sensors, causing only a slight reduction in sensing distance.
The 2-wire Uprox+ sensors are available in M12, M18, M30 and CK40 body styles with cable and quick-disconnect options. This provides an easy replacement for mechanical switches, as the new sensor can be connected to the existing cable network. Like all TURCK Uprox+ sensors, the 2-wire DC sensors are weld field immune and available with Teflon or TURCK's Weldguard coating for further protection in welding applications.
TURCK announces their Q-track family of linear position sensors has been expanded to include the newest QR14 and the Q17 models. Measuring just 14 mm and 17 mm in height, the compact, non-contact inductive sensors deliver dependable, repeatable measurements in applications with spacing limitations and harsh environments. TURCK's linear inductive sensor operation is based on the RLC resistance inductance capacitance principle. Unlike potentiometric or magnetostrictive technologies, the sensors incorporate precisely manufactured printed emitter and receiver coil systems.
The emitter coils are activated with a high frequency AC field and produce an inductive RLC circuit with the positioning element. The element is inductively coupled with the receiver coils, which are arranged so different voltages are induced in the coils, depending on the position of the actuator. The voltages serve as a measure for the sensor signal. Q-track sensors deliver maximum measuring spans, with minimal blind zone and high resistance to EMI/RFI noise interference.
Superior to alternative technologies, Q-track sensors' innovative design, linearity and repeatability eliminate common performance failures experienced with other technology options. The RLC principle of operation used in the Q-track linear position sensor is highly immune to noise interference and is inherently weld field immune. Since the position element does not contain a magnet, it can be used in metal working applications because it will not attract ferrous debris, which would affect the operation of a magnetostrictive sensor. Additionally, the inductively coupled position element provides non-contact position feedback ideal for use in applications with constant motion, such as pinch rollers, cylinder position, web tension control, pitch control, resisting damage and costly downtime.
Along with their advanced design features, the sensors' compact, durable construction increases functional flexibility. The QR14 and Q17 include both current and voltage outputs, eliminating the need for two separate sensors and offering greater convenience and cost efficiency. The fully potted and sealed IP67-rated housing protects against moisture and dust in demanding environments.
TURCK announces the new 7/8-16UN minifast explosion-proof feed-through receptacle that is certified as a secondary conduit seal by CSA. This quick disconnect solution may be used as a secondary conduit seal to prevent gas migration or as a boundary seal when used with a TURCK CSA certified cordset. It may be used in Class I, Division 2 locations without intrinsically safe circuits and Class I, Division 1 locations with intrinsically safe circuits.
The explosion-proof feed-through receptacle is fully potted in a durable 316 stainless steel housing and can withstand 2,000 psi of pressure. The receptacles install directly into 1/2-14NPT threaded conduit entries, and are rated for 600 V and 9 A. When used as a secondary conduit seal, the receptacles are limited to 30 V and 600 mA. It also provides IEC IP67 protection against liquid ingress when a mating connector is attached.
TURCK, inc. has expanded its diagnostic power conditioner (DPC) system with a Single Segment Redundant Backplane that can combine two isolated power supply modules into one FOUNDATION fieldbus segment.
The new backplane includes an integrated diagnostic unit used to monitor the redundancy of the external bulk power supply along with the H1 power supply-aiding in the availability of the H1 segment.
System status is available via a relay contact.
The backplane's small footprint (113mm high by 42mm wide by 210mm long) is designed for DIN rail mounting, and features separate connections for grounding and shielding.
The cable shield may be connected via shield clamps or screw terminals. Three-pole screw terminals with flange connections are also available to connect the segment outputs.
All Monitored Lamps must be the same wattage and voltage. The 0.5A solid-state output energizes when a flasher failure is sensed. When a LED beacon lamp fails, the FB senses a decrease in current flow. After a 10s lamp failure trip delay, the isolated SPDT (4-5-6) and non-isolated SPNO (3-1) relay contacts energize. These contacts are used to indicate a beacon failure has occurred. The "L" onboard LED
Its Dual Digital Display enables numerical setting while verifying setting items for each mode. Even when sensing, it enables the verification of the main settings. With a 25 µs ultra high sampling speed, the GP-X series won't miss even high speed work displacements. By combining the sensor head with the controller, we have realized 0.07 % F.S./°C. They are highly resistant to ambient temperature changes enabling stable microdisplacement measurements.
