Why Choose the IMO LDC22JK Safety Door Interlock Switch?
The IMO LDC22JK is a robust safety door interlock limit switch designed for monitoring guards, doors and access points on industrial machinery. Part of the IMO LDC metal-body safety switch range, it uses a separate-key operating principle to detect whether a movable machine guard is in the required position.
The LDC22JK features a 2 normally open + 1 normally closed (2 NO + 1 NC) contact configuration with slow-action switching. Its contact arrangement provides three switching contacts for integration into machine safety and auxiliary control circuits, while the mechanically operated interlock head is designed to work with a compatible actuator key.
Featuring a durable metal body, IP67 protection rating and 1 × PG13.5 cable entry, the LDC22JK is designed for demanding industrial environments. The switch is supplied without an actuator, allowing the appropriate compatible actuator to be selected according to the machine guard and installation requirements.

Reliable Guard Monitoring for Industrial Machinery
Separate-key interlock switches are commonly installed on movable machine guards and access doors. A compatible actuator is fixed to the moving section of the guard and enters the switch head when the guard closes, mechanically operating the contacts and allowing the control system to monitor the guard position.
The IMO LDC22JK combines a rugged metal enclosure with a three-contact slow-action arrangement. For safety applications, the switch and compatible actuator should be installed so that the required positive opening travel and operating force are achieved, with the complete guarding system designed in accordance with the applicable machinery safety requirements.
Typical Applications
- Industrial machine guard monitoring.
- Safety door and access-panel interlocking.
- Packaging and processing machinery.
- Automated production equipment.
- Conveyor and material handling machinery.
- Machine tools and manufacturing equipment.
- OEM machinery safety systems.
