Why Choose the IMO LRC5A34-20 Limit Switch?
The IMO LRC5A34-20 is a compact industrial limit switch designed for mechanical position, presence and end-of-travel detection in machinery and automated systems. Part of the IMO LR series, it combines a durable plastic body with a roller, sealed coil spring and rod actuator, providing flexible mechanical detection for moving machine components.
The spring-and-rod actuator provides greater tolerance to variations in target position than a rigid plunger, while the roller at the contact point helps moving components pass smoothly across the actuator. This configuration makes the LRC5A34-20 particularly useful for conveyors, handling systems and machinery where repetitive mechanical contact occurs during normal operation.
The LRC5A34-20 incorporates 1NO + 1NC snap-action contacts for rapid and repeatable electrical switching. Its compact plastic enclosure is equipped with a single M20 cable entry, making this version suitable for industrial installations requiring metric cable glands and straightforward integration into machine wiring systems.
Key Advantages
- Roller, sealed coil spring and rod actuator provides flexible mechanical detection.
- Roller contact helps reduce sliding friction during repeated machine actuation.
- 1NO + 1NC contact configuration provides normally open and normally closed signalling.
- Snap-action switching mechanism provides rapid and repeatable contact operation.
- Compact plastic body supports installation where mounting space is limited.
- Single M20 cable entry provides a practical metric connection for industrial wiring.
Key Features
- IMO LR series compact limit switch.
- Roller, sealed coil spring and rod actuator.
- 1 normally open + 1 normally closed contact.
- Snap-action contact mechanism.
- Flexible spring actuator accommodates variation in mechanical contact position.
- Roller tip provides smooth engagement with moving components.
- Compact plastic housing for machine-mounted applications.
- Single M20 cable entry for electrical connection.
Flexible Roller and Spring Position Detection
The IMO LRC5A34-20 combines a roller contact point with a flexible sealed coil spring and rod assembly. When a moving object contacts the roller and deflects the actuator, the internal snap-action contacts change state, allowing the switch to provide position or presence signals to PLCs, relays, contactors and other industrial control equipment.
This actuator arrangement is particularly useful where the target position may vary slightly or where a rigid actuator could be exposed to excessive mechanical stress. The spring provides compliance while the roller supports smooth contact with passing components, making the LRC5A34-20 well suited to repetitive sensing on conveyors, production machinery and automated handling equipment.
Typical Applications
- Machine position and end-of-travel detection.
- Industrial conveyors and material handling systems.
- Detection of passing products and machine components.
- Packaging and production machinery.
- Automated manufacturing equipment.
- OEM automation systems and machine building.

Frequently Asked Questions
What is the IMO LRC5A34-20 used for?
The IMO LRC5A34-20 is used for mechanical position, presence and end-of-travel detection in industrial machinery, conveyors, material handling systems and automated equipment.
What actuator does the LRC5A34-20 use?
The LRC5A34-20 uses a roller with a sealed coil spring and rod actuator, providing flexible mechanical operation while allowing moving components to pass smoothly across the roller.
What contact configuration does the LRC5A34-20 have?
The LRC5A34-20 uses the IMO C5 contact block with a 1NO + 1NC snap-action contact configuration, providing one normally open and one normally closed contact.
Why use a spring-and-roller limit switch?
A spring-and-roller actuator provides greater tolerance to variations in target position than a rigid plunger. The flexible spring absorbs deflection while the roller helps reduce friction as moving components operate the switch.
What cable entry does the IMO LRC5A34-20 have?
The LRC5A34-20 has a single M20 cable entry, providing a metric connection point for the cable gland used to route electrical wiring into the switch enclosure.
