Product Description:

The ZS2020-2820 is a circular power connector socket produced by Beckhoff within the ZS Motion Accessories series. As a female 7/8-inch interface, it is installed on motor cables, sensors, and distributed I/O boxes to deliver supply lines and feedback signals in automated machinery. The component provides the mating point between field wiring and motion equipment, allowing connection and disconnection without rewiring control panels.

Its mechanical profile follows the industry-standard thread of 7/8"-16 UN, so it mounts into bulkheads or device housings without additional adapters. The housing is formed from PA6 GF, a glass-fiber-reinforced polyamide that resists vibration and common lubricants encountered near moving axes. Electrical distribution is organized through a 5-pin layout that separates protective earth, supply, and signal conductors. When operated at the declared load, the connector carries 16 A at 40 °C, and its dielectric spacing supports up to 250 V AC or DC between contacts. An A-coded keyway prevents accidental cross-mating with incompatible pinouts, while the screw locking ring secures the coupling against rotational shock. Female contacts are accessed with screw terminations, and the design omits shielding for applications that do not require coaxial ground paths.

Reliability over field life is reinforced by an insulation resistance of ≥ 100 MΩ, which limits leakage current even in humid environments. Surge events on inductive loads can be tolerated thanks to a rated impulse withstand of 2.7 kV, protecting downstream drives and I/O modules from transient spikes. The screw clamp chambers accept conductors up to AWG16 (1.5 mm²), giving the connection enough capacity for full-load power without excessive temperature rise. After assembly, the threaded coupling remains functional for ≥ 100 mating cycles, sustaining repeated service access. The unified thread and termination design supports installation while maintaining conductor retention under vibration.
