Reed Sensor Datasheet 59025 Reed Sensor Description The 59025 Reed Sensor is a small cylindrical reed sensor, 25.4 mm (L) x 6.22 mm (Dia.) (1.00 x 0.245), with a choice of normally open, normally closed or change-over contacts. It is capable of switching up to 265 Vac/300 Vdc at 10 VA. The 59025 Reed Sensor is available with a range of sensitivity and cable length options. It is well suited for use in a wide range of industrial, appliances, or IoT proximity sensing applications. It functions best with the 57025 actuator. Features & Benefits Non-contact switching Can operate through solution for wet & non-ferrous materials (for harsh environments example, wood, plastic, or aluminum) No leakage current in open stateideal for battery- Available in select sensitivities powered IoT applications (operating distances) Additional Information Helps implement efficient Standard cable proximity/access and energy configurations customization management systems options available Compact size and easy UL Recognized per UL 508 installation and effective and CSA C22.2 No. 14. concealment in many applications Resources Accessories Samples Hermetically sealed, IP67 rated UL and REACH compliant Agency Approvals Applications Agency Agency File Number Security and access control Major appliances E61760 Factory automation Small appliances Note: Contact Littelfuse for specific agency approval ratings.
