SJE MilliAmpMaster™

Mechancially-Activated, Narrow-Angle or Wide-Angle Control Switch

Control switches accurately monitor liquid levels to activate pump control panels and alarms.

The SJE MilliAmpMaster™ control switch is narrow-angle or wide-angle control switch that offers control for AC or DC applications in wastewater and sewage.  The internal switching mechanism has seal gold cross-point contacts for reliable low current operation.  It features a blue colored cap for easy identification.

Common applications include PLC (programmable logic controller) panels, IS panels with intrinsically safe barriers, low current solar applications and other low current control panels and alarm applications.

The wide-angle version activates/deactivates at approximately 10.16 cm (4 inches) above and below horizontal with a 9 cm (3.5 inch) tether.  The narrow-angle version activates/deactivates at approximately 3.81 cm (1.5 inches) above or below horizontal with a 9 cm (3.5 inch) tether.

This switch is not sensitive to rotation.

Normally Open Models (high level): The control switch turns on (closes) when the float tips slightly above horizontal signaling a high level and turns off (opens) when the float drops slightly below horizontal. 

Normally Closed Models (low levels): The control switch turns on (closes) when the float tips slightly below horizontal signaling a low level and turns off (opens) when the float tips slightly above horizontal. 

SJE MilliAmpMaster™

Interruptor de flotador para paneles de control y alarmas, activado mecánicamente de ángulo estrecho o amplio.

El interruptor de control SJE MilliAmpMaster™ ofrece control para AC o DC en aplicaciones de agua y aguas residuales. El mecanismo interno cuenta con un sello de oro en los contactos de acción rápida para asegurar un funcionamiento fiable en baja corriente .Tienen una cobertura de color azul para facilitar su identificación.

Las aplicaciones más comunes incluyen paneles con PLC (controlador lógico programable), paneles IS con barreras de seguridad intrínseca, aplicaciones solares de baja corriente y otros paneles de control de baja corriente y aplicaciones de alarma.

La versión de ángulo amplio se activa / desactiva aproximadamente a 10,16 cm (4 pulgadas) por encima o debajo de la horizontal con una traba de 9 cm (3,5 pulgadas).

La versión de ángulo estrecho se activa / desactiva aproximadamente a 3,81 cm (1,5 pulgadas) por encima o debajo de la horizontal con una traba de 9 cm (3,5 pulgadas).

Los modelos normalmente abiertos (llenado): El interruptor de control se activa (se cierra) cuando el flotador está por encima de la horizontal y se apaga (se abre) cuando el flotador cae ligeramente debajo de la horizontal.

Los modelos normalmente cerrados (vaciado): El interruptor de control se activa (se cierra) cuando el flotador está ligeramente por debajo de la horizontal y se apaga (se abre) cuando el flotador sobrepasa ligeramente la horizontal.

Este interruptor no es sensible a la rotación.
