The DCNHR20PF24-01 is a normally open, single-pole single-throw DC contactor relay with a resin housing for corrosion resistance in harsh automotive environments. It has a 24 V DC coil and is rated for 20 A continuous current with main contact terminals featuring an internal thread. It operates from -40°C to +85°C, meets UL E47258 recognition and CE EN 60947-4-1:2018 standards, and is RoHS compliant. The contactor includes sealed contacts for arc containment and a mechanically linked normally open auxiliary contact. Ingress protection is IP67 for main contacts and IP54 for the PWM circuit. Torque for mounting is specified at 1.5 to 1.8 N·m for the M4 hole.
The DCNHR Series 900V Max High-Voltage DC Contactor Relay is normally open with a low-power coil in a corrosion-resistant housing for use in harsh vehicle environments. The contactor's permanent magnet helps to achieve a high-voltage DC cutoff.This DCNHR Series contactor relay (DCNHR20PF24-01) is for 20A contact switching and features polarized main contacts and a 24V coil. In addition, this model features contact terminals with an internal thread. Designed for 20 A contact switching Polarized main contacts 24 V coil rating
