Optimized Stroke Accuracy: Critical for maintaining the exact 3-15 psig spring range performance in pneumatic diaphragm actuators
offering maximum flexibility for site-specific requirements
preventing common electrical shorts in the field
Field Ready: Includes a 36-inch capillary and 1/4" flare connection for fast installation on standard refrigeration pressure switches
The end switches act as dry contacts to signal the air handler or zone panel once the damper has reached its full travel limit
Honeywell S301D2CO Sensor Refrigerant Optimized Stroke Accuracy: Critical forThe Honeywell S301D2CO is a heavy duty Carbon Monoxide (CO) sensor engineered specifically for classified hazardous areas requiring explosion proof gas detection. Designed as the direct 129431 L3 replacement, this sensor integrates seamlessly into existing 301 C controller systems via a Modbus RTU RS485 communication protocol. Built for industrial environments, the assembly features an electrochemical sensing element housed in a rugged enclosure,
