ALS-300 Description

Short technical summary and product information.

The Cooper Industries ALS-300 is a limit switch box designed with advanced engineering for solid construction and high quality. This model, the ALS-320N, incorporates an inductive proximity switch.

Key electrical specifications include a nominal voltage range of 8-30 VDC and a switching frequency of up to 1000 Hz. The rated operating distance for the proximity sensor is 3mm for the P16AM-D3N model and 2mm for the NJ2-V3-N model. It offers a 3-wire output type for the P16AM-D3N and a 2-wire NAMUR NC output for the NJ2-V3-N.

The ALS-300 features a compact and beautiful design with an aluminum die-casting housing. It includes a multiview visual position indicator, a "Quick-Set" cam, and a multipoint terminal strip with 8 standard points. Dual cable entries are provided, with G1/2 as standard and M20x1.5 or 1/2NPT as optional. The mounting bracket is designed in light of ISO5211 and NAMUR standards, with options for steel plate or stainless steel.

Environmental specifications include an IP67 weatherproof rating for the ALS-320N and Exia IICT6 explosive proof rating for the ALS-320Ni. The operating temperature range is -20°C to 85°C.
