Why Choose the IMO LDC20RRS Rope-Operated Safety Limit Switch?
The IMO LDC20RRS is a robust rope-operated safety limit switch designed for industrial machinery, conveyors and material handling systems where an accessible pull-wire stopping system is required. Part of the IMO LDC metal-body rope switch range, it combines rugged construction with a resettable rope-operated mechanism for dependable machine safety applications.
The LDC20RRS features a 1 normally open + 2 normally closed (1 NO + 2 NC) contact configuration with slow-action break-before-make (BBM) operation. This three-contact arrangement provides additional switching capability compared with simpler NO + NC versions, supporting safety monitoring alongside auxiliary signalling or control functions within an appropriately designed circuit.
With its metal body, IP67 protection rating and PG13.5 cable entry, the LDC20RRS is designed for demanding industrial installations. Its rope-operated configuration allows personnel to actuate the switch from positions along a correctly installed pull-wire system, making it particularly suitable for conveyors and elongated machinery.

Reliable Rope-Operated Safety for Industrial Machinery
Rope-operated safety switches allow personnel to actuate a machine stopping circuit from different positions along a tensioned pull wire instead of relying solely on individual local stop stations. This makes them particularly useful alongside conveyors, production lines and other elongated machinery where accessible stopping controls are required throughout the operating area.
The IMO LDC20RRS combines three contacts with slow-action BBM switching and reset functionality in an IP67-rated metal enclosure. The 1 NO + 2 NC arrangement provides additional circuit flexibility, while the break-before-make sequence ensures the normally closed contacts open before the normally open contact closes during actuation.
Typical Applications
- Conveyor safety and emergency stop systems.
- Material handling and distribution equipment.
- Production and assembly lines.
- Packaging and processing machinery.
- Automated manufacturing systems.
- Long machinery installations requiring accessible stopping controls.
- Industrial pull-wire and rope-operated safety systems.

Frequently Asked Questions
What is the IMO LDC20RRS used for?
The IMO LDC20RRS is a rope-operated safety limit switch designed for industrial machinery and conveyor applications where personnel need to actuate a stopping circuit from positions along a pull-wire system.
What contact configuration does the LDC20RRS have?
The LDC20RRS has one normally open and two normally closed (1 NO + 2 NC) contacts, providing three contacts for integration into industrial safety and control circuits.
What does slow-action BBM mean on the LDC20RRS?
Slow action means the contact movement follows the mechanical actuator movement rather than using a snap-action mechanism. BBM means break-before-make, so the relevant closed contacts open before the open contact closes during switching.
Does the IMO LDC20RRS have a reset function?
Yes. The LDC20RRS incorporates a reset mechanism for deliberate restoration of the switch following rope operation.
What protection rating and cable entry does the LDC20RRS have?
The IMO LDC20RRS is an IP67-rated metal-body rope switch and is supplied with one PG13.5 cable entry.
