Finder has announced new additions to its 19 Series of 35mm DIN rail module relays, adding override and status monitoring modules to the series.

Building management system (BMS) designers, panel builders and installers will find the new override modules essential for providing a manual override of a BMS controller or programmable logic controller, in an emergency situation or during maintenance.

The ability to manually override automatic systems provides crucial control in an array of situations, control that is typically missing in such systems.  This may include a controller failure, or where maintenance or safety issues must take precedence. 

Typically this can provide control over pumps, fans solenoid valves or motors, where manual intervention is required.

The status modules address a significant drawback of commercial or proprietary controllers; a lack of clear visual signal identification.  The new status module allows BSM and panel designers to set the colour of the status LED during installation, to create a more obvious alert indication.  This enables quick identification of operational status, particularly in complex systems, minimising downtime during fault conditions or routine maintenance.  An analogue output module has also been added to the range, providing a user-defined output between 0 – 10V, for proportional output setting or speed adjustment.

Wieland Electric has just launched an addition to its revos FLEX modular hybrid connector system, the RJ45 module.  Revos is a range of industrial multi-pole connectors.  It is also possible to transmit optical signals and connect compressed air hoses – all within a die-cast aluminum housing design.  The RJ45 module comes fully pre-assembled and is able to connect Ethernet cables.

The RJ45’s outer connections are implemented with standard female connectors and the inner section contains two USB connectors of type B, this ensures that improper contact between the internal connectors is avoided.  Revos FLEX has the option of four different frame sizes with two, three, five or seven module slots which can be inserted into the standard aluminum  die-cast housing of revos BASIC in size six through 48.

The module also has 28 different inserts for currents ranging from 1A to 82A and voltages up to 5.5kV which ensures the system can be used in a variety of applications.

Honeywell’s ES110 Series and ES120 Series are a modular range of inflow thermistor-based sensors specifically designed for use in the transportation industry.

Thermistors can be very effective in sensing temperatures of gases, liquids or solids because of their enhanced sensitivity, accuracy and reliability.

The ES110 Series air/gas sensor has an exposed thermistor element that offers enhanced response for greater levels of control, while the ES120 Series is primarily used for immersion temperature measurements. Its fully enclosed brass body makes it often ideal for applications requiring direct contact with liquids.

Robust and easy-to-install threaded packaging often provides reliable operation in harsh application environments. Fast response times over a wide operating temperature range of -40 °C to 150 °C [-40 °F to 302 °F] allow application flexibility.

FEATURES
• Air/gas or immersion sensing
• NTC (Negative Temperature Coefficient) or KTY (siliconbased positive temperature coefficient) type outputs
• Enhanced sensitivity
• Enhanced accuracy
• Enhanced reliability
• Robust packaging
• Fast response
• Wide operating temperature range
• Easy installation
• Customizable

POTENTIAL APPLICATIONS
• Transportation: engine coolant, oil temperature, air intake, fuel and engine block sensing
• Industrial: compressor, duct, hydraulic oil temperature sensing

The latest addition to Bulgin’s waterproof Ethernet Buccaneer connector system is a new EMI shielded backshell.

While Ethernet Buccaneer is a fully shielded system, the plastic panel connector, PX0833, does not have a natural bond or earth path to a metal chassis. The PX0833/E provides one solution with a short earth lead but there are occasions where complete shielding is required. This new metal backshell, PX0888, fits around the connector to provide a complete 360 degree bond to the panel therefore closing any potential EMI/RFI windows.

Assembly is very straightforward; the screening can fixes to the rear of the panel using the existing connector panel nut and a cover provides continuity between the connector screen and the can.

This simple accessory maintains screening directly to panel so will eliminate any potential EMC issues when using a plastic connector in electrically noisy environments.

Along with the recent introduction of two panel mounting connectors with PCB and IDC terminations this new shielding backshell further expands the uses of this popular IP68 rated Ethernet connector range.

Schurter’s MSM metal switch series has been extended to include a version with a double pole contact system. The new MSM DP switch is designed with two separate switching contacts. The separate contacts can be used as normally open, normally closed or as change-over. The MSM DP is ideal for potential free momentary switching action of electrical equipment. Furthermore, the switch can be used in applications where an additional second contact is required for a safety circuit. Typical applications are emergency switches where the control loop is switched, and in addition a second circuit for emergency services is activated.

Due to its flat front construction of 1.7 mm, a protection class of IP67 and a high shock resistance, the switch is extremely robust against vandalism. The MSM DP is available in mounting dimensions 19, 22 and 30 mm. The standard type is designed with switching capacities up to 3A / 250 VAC and 5A / 125 VAC respectively. For applications having other switching capacities, alternative variants are available on request. For night applications or where optical status indications are desired, point and ring illuminated versions in different colours are available.

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

POTENTIAL APPLICATIONS
• Industrial: HVAC, refrigeration, office automation, air compressors, industrial ovens and  ranges, hydraulic systems, processing and packaging, power generation
• Transportation: heavy duty or sport vehicle engine oil, air inlet, fuel, coolant or surface temperature sensing
• Aviation: engine bleed air or environmental control systems
• Weather stations

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.
