Switches

DIN-Rail Mount Miniature Toggle Switches

Built into a terminal block, these switches mount to DIN rail.

Two-Hand Safety Switches

It takes two hands to activate these switches, minimizing the risk of accidental equipment start up.

Barriers for Hazardous Location Proximity Switches

Safely transmit power to switches and sensors in highly volatile areas. Commonly used in refineries, power plants, and wastewater-treatment facilities, these barriers use a NAMUR signal to reduce the current and voltage coming from your power supply—preventing sparks and ignition.

Manual Motor Starters

Operated by hand, these starters are more compact than electrically actuated motor starters; use them when multiple motor circuits are housed in one panel.

Motor Starters

Provide on/off control for a motor and protect it from overloads. These starters shut the motor off if current exceeds the full-load current rating.

Low-Profile Motor Starters

With a shallower depth than most other starters, these fit in narrow spaces.

Reversing Motor Starters

Use these starters with motors that run forward and backward, such as motors for conveyor belts.

Energy-Saving Motor Starters

Save electricity and extend motor life by reducing the motor's starting current.

DIN-Rail Mount Programmable
Three-Phase AC Motor Speed Controls

Mount these controls to DIN rail inside a control panel.

DIN-Rail Mount Motor Voltage Monitors

Mount these monitors to DIN rail.

Ethernet Switches

DIN-Rail Mount Ethernet Switches

Mount these Ethernet switches to DIN rail to bring connections closer to where you need them.

ix Industrial Ethernet Switches

Link industrial equipment with multiple computers to expand your data network.

Relays

Screw Terminal Relays

Use the screw terminals to hardwire these relays.

Machine-Guard Safety Screw Terminal Relays

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding.

DIN-Rail Mount Infrequent-Cycle High-Current Relays

Mount these relays directly to DIN rail.

DIN-Rail Mount Long-Life High-Current Relays

With no moving parts, these solid state relays have an extended service life. Mount them directly to DIN rail.

High-Current Relays

Use these relays with large motors and lighting systems.

DIN-Rail Mount Long-Life Medium-Current Relays

Mount these relays directly to DIN rail.

Sequenced Latching Relays

These relays switch through a series of different circuit configurations every time they receive an input voltage. Also known as step relays.

Signal-Conditioning Ultra-Thin Signal Relays

Also known as input modules, these relays condition electrical signals into signals for PLCs and microprocessors and prevent power surges from reaching these devices.

Ultra-Thin Signal Relays with Socket

Plug these relays into the included socket for fast installation; they disconnect for easy replacement.

Ultra-Thin Signal Relays

Maximize space inside your control cabinet—these relays are extra narrow.

Signal Relays

Use these relays with circuits that control electric signals for PLCs and microprocessors.

Thin Signal Relays with PLC Protection and Socket

Prevent voltage spikes from damaging your programmable logic controller or other sensitive control device. Thinner than other signal relays, these fit in tight spaces.

Programmable Logic Controllers

Compact Programmable Logic Controllers

Smaller than other PLCs, these controllers save space in your control cabinet. They combine the functionality of a relay, timer relay, and switch in one unit, so you can program simple automation jobs.

Easy-Program Logic Controllers

Design and operate up to six simultaneous programs without symbols or technical language—the on-screen instructions use simple English.

Low-Current Timer Relays

Dual-Channel DIN-Rail Mount
Multifunction Timer Relays

Control two steps of an electrical process from a single relay—with two fully independent channels and 30 different functions, these relays give you a wide range of possibilities.

DIN-Rail Mount Multifunction Timer Relays

Control multiple timing functions from your electrical cabinet—these timer relays mount to 35 mm DIN rail (also known as DIN 3 rail), which is the most commonly used size.

Ultra-Thin DIN-Rail Mount Multifunction Timer Relays

Maximize space inside your control cabinet.

Long-Life DIN-Rail Mount Multifunction Timer Relays

With no moving parts, these solid state relays have an extended service life.

DIN-Rail Mount Timer Relays

Mount these relays directly to DIN rail.
