Electro-mechanical relays serve a wide range of industrial applications. Styles include ice cube and octal general-purpose relays, power relays for high-current applications, hazardous location relays for harsh environments, force guided relays, and space-saving slim-body relays.
Electro-Mechanical Relays
Category Selection
An electro-mechanical relay uses a magnetic coil and a moveable switch to open/close the circuit wired to the output contacts of the relay. The low-power input of the relay will magnetize the coil, and the electromagnetic force will force the switch to change state, either opening or closing the higher-power connection on the output side. Relays are typically offered with both normally open and normally closed contact options to either make or break the power connection to the load. Available models include:
- Slim interface relays
- Force guided relays
- General-purpose square relays, plug-in
- General-purpose octal relays, plug-in
- Hazardous location sealed relays, plug-in
- Power relays, open style
- Card relays
- Accessories, including relay sockets, relay removers, and protective covers, are also available

Slim Interface Relays
Slim interface relays provide a compact 6.2mm DIN rail mounted housing with a single-pole output in ratings up to 6A. Double-pole relays, manual/auto switches, and H-O-A toggle switches are also available in 12mm housings, with outputs up to 8A.
- Input voltage ratings up to 230 VAC/DC
- LED status indication
- Select models offer a built-in filter circuit on the coil for transient voltage suppression
- IP20 finger-safe protection rating
Starting at
$7.00
(KPR-SCF-230VAC-1)
Force Guided Relays
Force guided relays provide fail-safe operation via mechanically linked contacts to ensure all contacts move at the same time and prevent movement if any contact is immobilized.
- 24 VDC coil voltage
- 5A contact rating
- 4PST and 6PST contact configurations
- Available as plug and socket, or integrated module
- Polarity protection diode
