Littelfuse 59155-1-S-05-A

The 59155 is an ultra-miniature flange-mount dry reed sensor measuring 12.70mm × 9.00mm × 3.00mm (0.500 in × 0.354 in × 0.118 in) with normally open contacts. The housing design allows mounting with M2 screws at a maximum torque of 0.1Nm, or alternatively with adhesive. Leads exit from the right side as shown in Figure 2. A version with leads exiting from the left side is also available; see the 59156 series. The 59155 is capable of switching voltages up to 120Vac/170Vdc at 10VA. It is well suited for a wide range of industrial, home appliance, or IoT proximity sensing applications. The 59155 series works best with the matched actuator 57155-000.
