Contactor Features "Stackable" Poles To Suit Various Applications
The FM200 Flatman 480-V ac contactor fits a variety of applications, including power management and standby power equipment. The flexible design features 1-, 2-, 3-, and 6-pole configurations with either normally open or normally closed contacts in any order. The design flexibility of the "stackable" and modular poles allows the contactor to be used in a wide variety of applications.

This contactor features a rated operating voltage of 480 V and a maximum contact voltage of 750 V. It features a continuous current carry of 200 A rms/phase for normally open and 150 A rms/phase for normally closed. According to the company, it is the smallest contactor in the industry with its current rating. Its rated mechanical life is 1 × 106 cycles. An ambient operating-temperature range of −20°C to 60°C is featured. The Flatman is available with coil voltages of 12, 24, and 120 V ac.

In 100-unit quantities, a 3-pole Flatman contactor is priced at approximately $139.

Relay Modules Reduce Equipment Maintenance And Downtime
A family of safety relay interface modules are DIN rail- or panel-mountable. Multipole configurations, up to 16 channels wide, provide design flexibility and simplify panel layouts. According to the company, these configurations also reduce equipment maintenance and downtime.

The relay modules use force-guided and crown contacts that meet or exceed the TÜV, SA, SUVA, and UL standards. The force-guided contacts are mechanically linked to allow them to move together. Crown contacts feature two locations per contact for improved connections. Multiple contact materials are available to meet specific application requirements.

The safety relay interface modules are available in a variety of configurations. All are available with one to 16 relay channels. Optional coil voltages are 12 and 24 V dc. The modules are completely assembled with ready-to-wire screw cage terminal blocks. The modules can easily be snapped onto 32 or 35 DIN rails.

According to the company, these relay modules suit emergency stop and safety gate monitor applications. Pricing begins at $34 for a single-channel module in the DPDT configuration.
