Liquid Level Protection 

Sensor and Control Relays

460-15-100-LLS

Liquid Level Sensor

Description

The 460-15-100-LLS is a liquid level sensor to detect the 

presence of conductive liquids. A probe is mounted at the 

desired tank level and connected to the Littelfuse Pump 

Protection Relay. When the probe is submersed, the relay’s 

output contacts will change state as soon as the debounce time 

expires. The adjustable debounce timer is intended to prevent 

nuisance actuating due to waves or splashing in the tank. 
Relay logic can be inverted so the relay’s output contacts change 

state when the probe is no longer submersed. This makes the 

unit versatile for use in pump-up and pump-down applications.
