BURGESS E1M9CTQSA Product Description

Overview

BURGESS E1M9CTQSA is a heavy-duty snap-action limit switch from Burgess, belonging to the E1 series industrial micro switch family. BURGESS E1M9CTQSA is built for mechanical position detection and safety interlock signal output in industrial machinery and process equipment. BURGESS E1M9CTQSA delivers reliable instantaneous contact switching when actuated by cams, levers or mechanical stoppers.

Features

BURGESS E1M9CTQSA adopts robust metal housing construction and stable snap-action mechanism with consistent actuation force and fast contact transfer. It is equipped with side rotary actuator and SPDT changeover contact, providing 1NO and 1NC signal output for dual status feedback. The internal contact material is selected for long electrical life and resistance to arc erosion under rated inductive and resistive loads. BURGESS E1M9CTQSA supports flexible mounting orientation and can be fitted with optional lever accessories to match different stroke and actuation requirements. It has good vibration and shock resistance, suitable for continuous operation inside workshop machinery and control cabinets. The terminal design supports secure wiring and reduces loose connection risks. BURGESS E1M9CTQSA complies with UL and IEC standards and can be used for safety interlock, travel limit and valve position monitoring.

Specs

Brand: BURGESS Model: E1M9CTQSA Product category: Snap-action limit switch Series: E1 Actuator type: Side rotary Contact form: SPDT 1NO+1NC Operation type: Snap action Housing: Metal enclosure Certification: UL, IEC Mounting: Screw mounting Function: Position detection, travel limit, interlock signal

Principle

BURGESS E1M9CTQSA works when mechanical movement pushes the rotary actuator. The internal spring-loaded snap mechanism triggers instantly and switches the contact state. The changeover contact sends discrete on/off signals to PLC or safety relay. BURGESS E1M9CTQSA converts mechanical displacement into electrical digital signals, and the snap-action design ensures clear and fast switching without contact chatter. When the actuator is released, the internal spring resets the contact to the original state.

Applications

BURGESS E1M9CTQSA is widely used in general industrial automation equipment. It is commonly applied in packaging machines, conveyor systems, machine tools, lifting equipment, valve actuators and material handling machinery. It is used for travel limit stop, door safety interlock, mechanical home position detection and equipment fault interlock protection. It can cooperate with safety modules and sensors to build reliable position monitoring circuits.
