Littelfuse 59156-1-T-05-A

The 59156 is an ultra-miniature flange-mount 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 non-magnetic M2 screws at a maximum torque of 0.1Nm, or by adhesive mounting. Leads exit from the left side; see Figure 2. A right-side lead exit version is also available; see the 59155 series. The 59156 is capable of switching voltages up to 120Vac/170Vdc at 10VA. It is ideally suited for a wide range of industrial, home appliance, or IoT proximity sensing applications. The 59156 series works best with the matched actuator 57155-000.
