Why Choose the IMO AB1/CP-3A M4 Inductive Proximity Switch?
The IMO AB1/CP-3A is an ultra-miniature M4 shielded inductive proximity switch designed for precise, contactless detection of metallic targets in compact industrial machinery and automation systems. Its threaded M4 cylindrical body provides an exceptionally small sensing solution for applications where mounting space is limited.
The AB1/CP-3A provides an extended nominal sensing distance of 1 mm and uses a PNP normally closed (NC) output. Operating from a 10–30 V DC supply, it can interface with compatible PLCs, machine controllers and other industrial control equipment for position and presence detection.
A robust AISI 303 stainless steel housing, IP67 protection and integral 2 m PUR cable support reliable use in demanding machinery environments. The sensor also incorporates a yellow output-state LED together with short-circuit and reverse-polarity protection.

Reliable Precision Metal Detection
The IMO AB1/CP-3A detects metallic targets using an electromagnetic sensing field, allowing position and presence to be monitored without mechanical contact. This contactless operating principle reduces wear and makes inductive sensing particularly effective in machinery with frequent switching cycles.
With its 1 mm extended sensing range, miniature M4 body and 3.5 kHz switching frequency, the AB1/CP-3A is well suited to compact and fast-moving automation equipment. Its shielded design permits flush installation, while the stainless steel housing and IP67 protection provide durability for industrial use.
