Wieland Electric has completed its selos DIN rail terminal block range with the addition of the WKN 6 TK instrument isolating terminal, a screw-type terminal specially designed for use in secondary circuits of measuring transformers.  

It short-circuits the current transformer for safe disconnection or separation of measuring devices, which prevents both overheating and generation of high voltages in the secondary winding.

The 500 Series is broad portfolio of air/gas, liquid and surface temperature probes that use Honeywell's NTC (Negative Temperature Coefficient) thermistors.

Thermistors can be very effective in sensing temperatures of gases, liquids or solids because of their enhanced sensitivity. These small, easy to install probe assemblies support and position the thermistor elements within the media to be monitored as well as protect the thermistors against damage in use or handling. The assemblies also help direct thermal or fluid flow evenly across the thermistors for accurate temperature sensing.

The enhanced reliability, precision and stability of the 500 Series products allow the customer greater flexibility in temperature monitoring and control. The wide operating
temperature range is -60 °C to 300 °C [-76 °F to 572 °F] provides application flexibility.

The 500 Series is available in a wide variety of housing styles and materials, R-T (Resistance-Temperature) curves, mounting methods, mechanical interface, electrical interface and connector types to meet most applications.

In addition to custom configurations, a variety of existing designs is available.

Honeywell also offers RTD (Resistance Temperature Detector) technology that may be packaged into probe assemblies for similar applications that may require an RTD linear output instead of an NTC thermistor output.

FEATURES
• Air/gas, surface, immersion and liquid level
• NTC type output
• Enhanced sensitivity
• Small package size
• Easy to install
• Enhanced reliability
• Enhanced accuracy
• Enhanced stability/low drift
• Wide operating temperature range
• Wide variety of probe assembly styles
• Custom configurations available
• RTD linear output available

The latest addition to Bulgin’s extensive range of Vandal Resistant Stainless Steel Switches is a new double-pole version.

Rated at 3A 125Vac, the new MPD031 has double pole changeover switching. The switch retains the same rugged construction as others in the range, the barrel and button are CNC turned from high grade stainless steel to produce a very strong, rugged switch capable of withstanding abuse. Three profiles as are available; low profile, prominent and domed, and the switch is front panel sealed to IP66.

The panel cut-out, 19mm diameter, and external dimensions remain the same as the single pole MP0031 making the MPD031 suitable as a drop in replacement, therefore it is ideal for applications where more complex switching is required but without taking up any more real estate on the panel.

The new and first of its kind power entry module, Schurter series 5707, advances the range of applications in the area of detachable power. It offers an alternative to makeshift accessories often used to prevent particles or liquids from entering into the appliance. The new power entry module is resistant to dirt, dust and other fine particles, as well as sprays, splashes and jets of non-aggressive liquids. It is ideal for use in electronic equipment exposed to leaks, drips and spills, as well as equipment subject to routine washing or disinfecting.

The inlet portion of the 5707 is according to IEC 60320-1, style C14 or C18. It is combined with a 1-or 2-pole fuse holder and a standard or medical EMC filter rated up to 8 Amps at 250 VAC. The complete unit is rated IP65 with seal protection at the panel opening, around the fuse holders and between the inlet and connector pins. The seal at the panel opening is achieved with a rubber lining, which is fixed into a groove around the metal flange. Front or rear mount versions are available. Special screws guarantee the sealing at the mounting holes.  The fuse holders are independent of each other and accept 5x20 mm fuses. Screw caps with o-rings are used to provide a seal between the cap and holder. A tool is required to remove the cap from the holder to replace the fuse, which is required for medical equipment.

The 5707 offers pre-wired electrical connections, using 6.3x0.8 quick connect terminals. The series is approved according to ENEC, UL & CSA. Versions for protection class I or II are available, as well as a version with special class I capacitors for increased voltage withstand. The module is according to medical standards IEC/UL 60601-1 and is ideally suited for use in medical applications such as diagnostic, dialysis and infusion devices, as well as commercial appliances such as drink dispensing equipment.

This latest addition to Bulgin's Data Buccaneer range of dust and waterproof connectors is a new Mini USB 'AB' style interface in three panel mounted configurations.

These three new 'AB' versions offer a choice of panel mounting. The first, PX0456, is front of panel mounting with a flying lead to the rear, terminated with a 6 way 0.1” crimp connector.

The other two are rear of panel mounted; the PX0457 has a flying lead terminated with 6 way PCB header and the PX0458 has straight PC pins for direct soldering to a PCB. Both of these allow the connector to be soldered to a PCB sub-assembly and tested as part of the assembly before final build.

Being compatible with both mini 'A' and mini 'B' style interfaces this new 5 pole product allows the true functionality of this 'plug and play' interface.

As with others in the Buccaneer range, the mini USB connector is dust and waterproof to IP68, when mated, and provides USB V2.0 performance up to 480Mbs.

The matching pre-wired cable connectors, PX0441 and PX0442, are available in 2, 3 and 4.5m lengths with a sealed Mini 'B' type USB connector paired with either standard or miniature 'A' type USB connector. The diameter over the coupling ring is just 19mm and the screw coupling provides a secure, proven locking system.

Mini USB Buccaneer finds many applications within smaller peripherals or where panel space is at a premium and, as with all Bulgin products, is fully RoHS compliant.

Patent-Pending Design Allows for True Plug-and-Play Installation

Honeywell introduced an adapter for limit switches with 20mm thread conduit openings. When purchased as a pre-installed accessory on a Honeywell MICRO SWITCH limit switch, this patent-pending adapter is ready to mount and plug into a Deutsch DT4 mating connector.

Typical installation time for limit switches includes as much as three minutes to wire a standard-type switch. The plug-and-play adapter may realize cost savings in reducing installation time, minimizing down time for switch replacement, or by eliminating additional parts normally associated with the assembly of a pigtail connector.

The accessory also is available as an adapter kit containing individual parts ready for assembly or as an adapter assembly pre-wired with four lead wires. Both options may provide cost savings over standard installation. Potential applications include aerial/scissor lifts and cable-to-cable applications in off-road, agricultural and construction equipment.
