Motion Control
Rotary Limit Switches
Rotary Cam Limit Switches are fully adjustable multi limit switch units. Ideal for stroke position indication on screw jacks or linear actuators with limit switches that can be individually set to any position over the entire stroke.
The RLS-51 is available with 2 to 8 limit switches as standard in a robust IP66 housing available in B14 (face), B5 (flange) or B3 (foot) mount options.

Key Features
Rotary CAM Limit Switches allow a set of limit switches to be fitted to screw jacks, linear actuators or gearboxes by mounting them directly to the unit or in-directly via connecting shafts or gearboxes.
These limit switches are fully adjustable for position over the entire length stroke of a screw jack or linear actuator. RLS-51 limit switch features include:-
- 6 Models, up to 8 Limit Switches in one unit
- Up to 16000 useable revolutions before limit switch cam repeats
- Limit switches individually adjustable over revolution range
- Electro-mechanical limit switches with change-over contacts for Normally Open or Normally Closed arrangements
- Mounting options for B5 Flange, B14 Face and B3 Foot mounted
- Modular design to allow a variety of options
- Reinforced polycarbonate enclosure IP66 as standard
- Available in 250 VAC, 24 VDC and 80 VDC
- Suitable for Screw Jack and Linear Actuator mounting
- Encoder, Potentiometer and Anti-Condensation Heater options
- Operating Temperature: -40°C to +80°C
- Industry proven for industrial and human cargo applications
Refer to Screw Jack Design Guide for details.
Design Options
- Anti-condensation heater to prevent condensation and excessively low temperatures in the switches
