The 59135-1-T-02-F is a high-temperature flange-mount reed sensor measuring 28.57 mm × 19.05 mm × 6.35 mm with a 300 mm cable length and untinned lead termination. This magnetically operated proximity sensor features a two-part design with hermetically sealed contacts and operates up to 150 °C, making it suitable for harsh industrial environments where optical and other sensing technologies fail due to contamination. The sensor is rated for switching up to 265 Vac/300 Vdc at 10 VA with a pull-in activation distance of 17.1 mm (0.673 inch) in its standard T-sensitivity configuration, and includes cross-slotted mounting holes for optimum adjustability. It operates through non-ferrous materials such as wood, plastic, or aluminum without requiring standby power, making it ideal for position and limit sensing, security systems, linear actuators, and door switches.
