Honeywell Sensing and Control Zephyr Analog Airflow Sensors

Honeywell Zephyr™ Analog Airflow Sensors: HAF Series-High Accuracy, provide an analog interface for reading airflow over the specified full scale flow span and temperature range. Their thermally isolated heater and temperature sensing elements help these sensors provide a fast response to air or gas flow. Zephyr sensors are designed to measure mass flow of air and other non-corrosive gases. They are available in standard flow ranges and are fully calibrated and temperature compensated with an on-board Application Specific Integrated Circuit (ASIC). The HAF Series is compensated over the temperature range of 0° C to 50° C [32° F to 122° …

IDEC HE6B Three-Position Enabling Switch

IDEC’s new HE6B three-position enabling switch is ergonomically designed to work where human interaction is required to turn on a machine or robot while the user is in a potentially dangerous area. Typically, enabling switches are installed in grip switches or pendant stations. This 3-position enabling switch not only turns a machine on when pressed, but also turns machines off when over pressed or squeezed, as long as the switch is installed correctly in an adequate safety circuit. Two contacts are provided so that even if one contact fails, the other can disable machine operation. Functionality is the same as …

IDEC HS1L Interlock Safety Switches

New HS1L series interlock safety switches from IDEC have an increased locking strength of 3,000N and offer six contacts with easy-to-wire termination. HS1L safety switches are designed to work in applications with large machines that have heavy doors or gates and all models are equipped with a manual lock-release key and an LED indicator. The indicator is wired independently, for added flexibility and use. Screw terminals are also easy to wire. No barriers on the sides of the contact terminal enable wiring from the side, making it easier for crimp-terminal connections as well. IDEC HS1L Interlock Safety Switches IDEC Technical …

Phoenix Contact LINETRAB LIT Compact Surge Protection for MCR Technology

Transients induced onto the signal lines often cause costly damage and downtime. Therefore, surge protection for MCR technology is indispensable. At the same time, there is a demand to save space and reduce wiring time, all at a minimum cost. Phoenix Contact’s new LINETRAB LIT are space-saving surge protection devices for the MCR technology. Up to 4 signal cores can be protected on a design width of just 6.2 mm. Three/four-wire measurements can thus be realized with just one arrester, thus saving space in the control cabinet. Even with its low article variety, the LINETRAB product range provides the ideal …

Phoenix Contact PSR-ESAM 3×1 and 2×1 Safety Relays

Phoenix Contact has added four new part numbers to their safety relay range. One version has three redundant normally open (NO) contacts and one normally closed (NC) status contact. Another version has two redundant NO safety contacts and one NC status contact. Both are available in either spring or screw connection. These new relays can be reset with either a monitored manual or automatic reset. Previous relays required you to choose which type of reset (monitored manual or automatic) is required. The PSR-ESAM relays eliminate the need to understand the reset circuit, simplifying your selection. Phoenix Contact PSR-ESAM Safety Relays …

Phoenix Contact PSR-FSP Process Safety Relay

The PSR-ESP (2981020) is Phoenix Contact’s original Safety Integrity Level (SIL)-rated or process safety relay. Some of the largest process companies in the world currently use this relay. It has also been Phoenix Contact’s best-selling safety relay over the last several years. Experience with these high-profile process customers has led to a smaller, more advanced and a slightly less expensive relay, the PSR-FSP. Features: Completely compatible with the “test pulses” occurring on safe PLC/DCS outputs Inrush requirement is limited for safe PLC/DCS output compatibility Built-in fuse for the safe output contact One normally open redundant safety output and one normally …

Rittal CP-C Support Arm System

Machine controls often need to be easily moved into a position for use, adjusted to the user’s height, then pushed out of the way when the operation is complete. That’s when a support arm system is ideal — get the needed changes made, then get the enclosure off to the side. Rittal leads the way with innovative pendant arms and the housing. For heavier applications the Rittal CP-XL support arm system is ideal, and for lighter loads you can use the CP-L. Right in the middle is the CP-C, which has been configured for use with Rittal’s OptiPanel and Comfort …
