Inclination Switches / Reed sensors

Tilt switches and reed sensors – position feedback for the platform

Tilt switches with reed contact report to the control unit whether the platform of a tail lift is in the intended position – typically horizontal for loading or unloading. An integrated steel ball or a pivoting magnet triggers the glass-tube contact at a defined switching threshold. At SULEJ Ladebordwand you will find tilt switches and reed sensors in different switching angles and connection variants, matched to the respective installed component – for reliable position monitoring in daily truck operation.

Reed contact and pivot mechanics – discrete switching point in a compact space

The reed contact inside the housing consists of two ferromagnetic blades that touch or separate under a sufficient magnetic field. In a tilt switch this contact sits together with a pivoting permanent magnet in a small chamber; when the platform leaves the tolerance range, gravity changes the magnet position and the contact switches. This purely passive design requires no auxiliary energy to hold the switching state and operates bounce-free. Different switching angles and cable variants are precisely matched to typical platform geometries.

What to look out for when replacing a reed tilt switch

When replacing, the nominal switching angle, the mounting orientation to the platform axis and the switching logic – normally-open, normally-closed or changeover – are decisive. Check the glass tube through the transparent housing window for cracks, the potting resin for cloudiness and the cable exit for kink damage. A careful test with controlled tilting shows whether the switching point is reached cleanly – stiffness, latching or repeated switching are clear indicators for replacement.

Benefits at a glance

• Passive position detection without auxiliary energy for holding the state
• Switching angles and cable variants for common platform geometries
• Potted housings with high resistance to spray water and vibration
• Bounce-free contacts for stable signal evaluation at the control unit

A precisely matched reed tilt switch provides clear platform position feedback and supports correct sequence control of the lift gate.
