Power relays are devices used to control, protect, and isolate electric circuits. These devices use a magnetic field to move an armature from an open to a closed position, or vice-versa. The OJ-SS-105LM,000 is a general-purpose power relay manufactured by Omron Corporation. It is suitable for use in diverse fields such as motor control, appliance control, and HVAC. It is a mechanical latching type, and requires an initial coil pulse to switch, and a second pulse to switch it off.

Technical Specifications

The OJ-SS-105LM,000 is a Class B type power relay with a rated voltage of 250 VAC and a rated current of over 2 amps. It has a wide range of contact forms, including 1 Form A (NC), 1 Form B (NO), 1 Form AB (Changeover), and 1 Form C (Delay). It is composed of five terminals and one common designed for various wiring types. It also has an operating range between 0 to +70 degrees Celsius and a nominal mechanical life of 1,000,000 operations.

Case Design

The OJ-SS-105LM,000 is housed in a standard black polyester resin case. The dimensions of the case are 30mm x 18mm x 14mm with a height of 24mm including the pins. The case includes a socket socket design to ensure easy and safe installation. It also provides environmental protection ratings of IP20 and IP67, which makes it suitable for a wide range of applications.

Mounting Types

The OJ-SS-105LM,000 is designed for PCB mount (through-hole) or pluggable socket mount. The device comes with an easy to use snap-in style mounting for a secure connection. Additionally, the device benefits from its space-saving design, which makes it ideal for use in small and compact panels.

Coil Types and Structure

The OJ-SS-105LM,000 is available in four coil types; DC3 (3 VDC), DC5 (5 VDC), DC12 (12 VDC) and DC24 (24 VDC). The device is composed of a single pole designed structure for a uniform force distribution. This ensures reliable switching performance and a high contact capacity of 5A.

Working Principle

The working principle of the OJ-SS-105LM,000 is simple and straightforward. When an electrical pulse or signal is applied to the coil, the actuator moves towards its intended position, and the contact field is engaged or disengaged. In the case of an inductive load, when current is cut off, the actuator springs back to its original position. The electrical connection is thus opened, and the contact field is reset.
