Series 61 Photoelectric Sensors for Machine Builders

Series 61 photoelectric sensors enable machine builders to benefit from the powerful optical performance without the cost traditionally associated with high optical power. These UL and cUL listed photoelectric sensors are available in DC models with our exclusive 4-in-1™ output and AC/DC models with SPDT relay output, for an all-in-one solution that satisfies any number of application needs. Easily accessible controls simplify set-up and adjustments, and color-coded labels make it easy to identify a given sensor’s sensing mode.

“Series 61 has a rugged IP67 industry standard housing style to make it a simple drop-in replacement in many applications, while delivering optical performance that is anything but ‘standard’ - in fact these sensors deliver the best optical performance available today in sensors with similar housing styles,” says Michael Turner, Product Manager, Pepperl+Fuchs. “And because each sensor has a one-piece design and comes standard with a multifunction timer, sensitivity adjustment, and the choice of a 4-in-1 output or SPDT relay, selecting the right sensor for the application has never been easier.”

The 4-in-1 output automatically sinks or sources depending upon the load detected, simplifying set-up while reducing costs and stock requirements by delivering four output options from a single photoelectric sensor. Both 4-in-1 output models and SPDT output models include standard diffuse mode with a 1 m or 4 m sensing range, diffuse with background suppression mode with a 500 mm or 2 m sensing range, polarized retroreflective mode with an 18 m sensing range and thru-beam mode with a 60 m sensing range.

AC/DC versions with SPDT relay output are capable of switching up to 3 amps. For the harshest applications, Series 61 photoelectric sensors are also available in fiber optic versions where the sensing range is dependent on the fiber cable. The fiber optic fitting is suitable for use with all “universal” glass fiber optic cables.

AC/DC Series 61 connection options include a 2 meter fixed cable or a 5-pin, Mini-style quick-disconnect. DC Series 61 connection options include a 2 meter fixed cable or a 4-pin, M12 micro-style quick-disconnect. Each sensor can be mounted via front and rear slots, rear dovetail guide or M30 x 1.5 mounting base. Additionally, cabled sensor models provide 0.5 in. – 14 NPT internal threads for use with flexible conduit.

Series 61 sensors are an ideal solution for over-the-conveyor package detection in material handling industries, as well as automotive part positioning. Additional applications where these sensors shine are industrial door control, palletizing, reliable parts detection in hot environments, overhead conveyors and small or slotted object detection.

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.
