Description:
The 59156 is a subminiature flange mounting reed sensor 12.70mm x 9.00mm x 3.00mm (0.500’’ x 0.354’’ x 0.118’’) with normally open contacts. The case design enables mounting with non-magnetic M2 screw at 0.1 Nm torque maximum or adhesive mounting. The wires exit from the left-hand side. It is also available with right-hand exit, see 59155 series. The 59156 is capable of switching up to 120Vac/170Vdc at 10VA.
It is well suited for use in a wide range of industrial, appliances, or IoT proximity sensing applications. The 59156 series functions best with the matching actuator 57155-000.
- Smallest flange mount type reed sensor in the market
- Non-contact switching solution for wet & harsh environments
- Housing design for optimum adjustability
- Available in select sensitivities (operating distances)
- Standard cable configurations; customization options available
- No leakage current in ‘open’ state−ideal for battery powered IoT applications
- Can operate through non-ferrous materials (for example, wood, plastic or aluminum)
- Helps implement efficient proximity/access and energy management systems
- Easy installation and effective concealment in many applications
- UL Recognized per UL 508 and CSA C22.2 No. 14
