LED Flange Mount > 55110
55110 Miniature Flange Mounting Proximity Sensor
Description
The 55110 is a flange mounting hall effect sensor with integral LED for visual
indication of operation, 34.00mm (1.339”) x 14.00m (0.551”) x 10.00mm (0.394”)
with a choice of digital outputs. It is available as three-wire (voltage output)
version and it’s case design enables screw or adhesive mounting. It is capable of
switching up to 28Vdc and 20mA. It works best with the operating magnet with
the Littelfuse part number H-58.
Features
• Magnetically operated position
sensor
• Integral LED
• Medium or high sensitivities
