Linear 2500-009 is an OEM replacement contactor from Linear (also sold under the OSCO, Nortek, and Linear PRO Access brand names). OEM 115 VAC coil 4-pole single-direction contactor for Linear gate operator motor control. Key attributes include 115 VAC coil voltage and 4-pole contact configuration. Compatible with the Linear slide gate operators and Linear swing gate operators families.
A: The coil voltage is 115 VAC. Do not substitute the 24 VAC version (2500-008) as the coil voltages are not interchangeable.
A: Both are 4-pole single-direction contactors. The only difference is the coil voltage: 2500-008 uses 24 VAC and 2500-009 uses 115 VAC. Always match the coil voltage to your control board output.
A: Sd stands for single direction, meaning the contactor energizes the motor for travel in one direction only.
A: The 2500-009 is used in Linear gate operator systems where the control circuit operates at 115 VAC rather than the lower 24 VAC level.
A: Check the coil voltage marking on the original contactor or refer to the wiring schematic in your gate operator manual to confirm whether 115 VAC or 24 VAC coil power is present.
