New Speed Sensor from Cherry Targets Harsh Environments

Cherry's new GS102301 gear tooth speed sensor is perfect for any application where rugged, dependable speed sensing is required. This digital output Hall Effect sensor is self-adjusting over a wide range of magnetic flux densities, eliminating the need to optimize the sensor position within a small magnetic flux operating range. This feature also compensates for target run out. The single hall plate design is immune to alignment issues, allowing unlimited mounting positions.

This addition to Cherry's family of near-zero speed sensors operates in temperatures ranging from -40 degrees C to 140 degrees C and meets IEC60529 IP68 standards for water immersion. The sensor also contains circuitry that protects it from EMI and ESD and is reverse battery protected. The device requires a minimum input of 3mA to function properly.

Only 2.80" long, in a straight, threaded housing, this sensor will fit into a standard M20 x 1.5 o-ring port and withstands a maximum installation torque of 15 ft lbs. The Viton o-ring comes pre-installed. The durable Stanyl® plastic housing, with its resistance to environmental extremes, makes it suitable for a wide range of speed sensing requirements in transmission, engine and braking applications. The device has been tested for environmental exposure per SAE J1455 Section 4.4.1, which includes immersion in engine and transmission oils.

Manufactured with an open collector output, the GS102301 requires a customer supplied pull-up resistor. Operating voltage is 5 to 30VDC at the nominal operating range. The GS102301 mates with the Packard Metri-Pack 150.2 sealed female connector assembly 3F.

Banner Engineering DF-G3 Discrete Fiber Amplifier Features World-Class Long Range Sensing Capability

Banner Engineering introduces its DF-G3 discrete long-range fiber amplifier with dual digital displays for use with plastic and glass fiber optic assemblies. Featuring increased sensing power, the DF-G3 can sense more than 3 meters (10 ft.) with opposed mode fibers or more than 1 meter (3 ft.) with diffuse mode fibers. The extra power provides increased detection reliability for dark targets at long range and enhanced detection sensitivity when using specialty fiber assemblies for large area and small part detection applications.

The DF-G3 is available with a single discrete output or two dual discrete outputs. The dual discrete outputs can be independently taught to trigger at different intensity values, which is ideal for correct part-in-place or error-proofing, bottle down, and edge guiding applications.

“We developed the DF-G3 fiber amplifier to meet our customers’ need to precisely detect smaller targets at longer ranges” said Dennis Smith, Senior Marketing Manager, Banner Engin…

TURCK M8 CORDSETS WITH 100 PERCENT SHIELDING OPTION PROTECT AGAINST EMI/RFI

TURCK is now offering the option to completely shield M8 picofast ® cordsets by connecting a braided shield directly to the coupling nut. This provides a cost-effective and reliable connection with 100 percent cable and connector shielding, which protects against electromagnetic and radio frequency interference.

The 3 and 4-pin cordsets are available with flexlife ® PVC or PUR jacketed cable. All connectors deliver IEC IP 67 protection.

The M8 picofast line, like most TURCK cordsets, provides male or female, straight and right angle connectors, standard and custom lengths, and pigtails or extensions. Fully encapsulated mating receptacles are also offered, completing the system.

TURCK’s BL Compact Family Collects Analog and Digital Signals at the Source

TURCK’s BL Compact system is a revolutionary modular I/O solution for collecting a variety of signals in a single, rugged node on a network. Rather than routing all signals through a control cabinet, this device makes it possible to obtain analog, digital, thermocouple, RTD, serial, RFID or a mixture of signal types in a compact, machine-mountable device over DeviceNet™, CANopen and PROFIBUS ®.

Up to two signals types can be combined in any combination in the BL Compact system, including RFID and analog, digital and serial—and more. The BL Compact system may be customized to suit a user’s specific needs, so that devices may be added to an existing network and signals may be gathered on the machine without an enclosure. This drop-in solution can be used to connect up to 16 devices—drastically reducing the time it takes to run wires for each device back to the control cabinet and the potential for wiring errors.

The BL Compact system is currently available with four, eight or 16 ports i…
