First Sensor Introduces the QP154-Q Photodiode for Laser Guidance Applications

First Sensor’s Q series photodiodes for 1064 nm are ideally suited to laser rangefinders, laser-based guidance systems, and for all applications needing the best detection of radiation from YAG lasers or comparable NIR radiation sources. With the photodiode QP154-Q, First Sensor is introducing a new development that is unique in Europe.

QP154-Q is a quadrant detector that is optimized for laser guidance under extremely difficult conditions. Its construction is fully hermetic and includes an integrated and exceptionally powerful heating element that can bring the element to optimal operating temperature in just seconds. The product is tested for ambient temperatures of -55°C to +125°C and holds up to high levels of shock and accelerations.

“High tech – made in Germany" applies to every component of the product. The p-on-n silicon photodiode with high responsivity at 1064 nm, high uniformity, very low dark current and fast rise time is manufactured at First Sensor’s parent plant in Berlin based on decades of experience. The hermetically sealed housing including the low profile cap with soldered flat glass window was developed and delivered by Schott AG in Mainz, Germany. First Sensor’s Swabian subsidiary Lewicki microelectronic GmbH is responsible for the design and assembly of the high performance heating element. Lewicki has been on in the market for 45 years and specializes in and is approved for the manufacturing of components for aerospace technology.

Every component can be modified on individual requirements. The quadrant photodiodes for 1064 nm can be manufactured in p-on-n as well as n-on-p technology with specific optimizations of speed and sensitivity. Furthermore, the heater element and the package layout can be specifically matched to the application.

We are proud to introduce a product that fulfils the highest requirements. Its outstanding features are the result of combining specialist technical knowledge within the First Sensor Group and its traditional good connections to the best German suppliers.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
