Why Choose the EMAS SMB18 Magnetic Door Switch Actuator?
The EMAS SMB18 is a plastic magnetic actuator designed for use with compatible EMAS SM Series magnetic door switches. With a nominal 78 mm format and 8 mm sensing distance, it provides the magnetic target required by the associated switch for reliable non-contact monitoring of industrial machine doors, guards and access points.
As a passive actuator, the SMB18 requires no electrical wiring or power supply of its own. It is installed on the movable part of the guard or door opposite a compatible 78 mm EMAS SM Series magnetic switch, allowing the sensor to respond as the actuator enters or leaves the specified sensing range.
The SMB18 features a plastic body, operates across a temperature range of -25 °C to +70 °C and carries an IP67 protection rating. Its non-contact operating principle and resistance to dirt and dust make it a practical actuator for industrial automation and machine-door monitoring applications.

Reliable Non-Contact Door and Guard Monitoring
Magnetic door switch systems use a sensor mounted on the fixed machine structure and an actuator mounted on the movable door or guard. As the door closes, the actuator approaches the sensor and its magnetic field causes the compatible switch to change state, enabling the associated control system to determine whether the monitored door or guard is in position.
The EMAS SMB18 is the 8 mm actuator for compatible 78 mm SM Series magnetic door switch configurations. Because the actuator itself is passive and operates without mechanical engagement with the sensor, it provides a simple, wear-free means of actuating compatible magnetic switches in industrial installations.
