Product Description:

The HCMCO1-A is a small electromechanical module. It is used for high-precision switching applications where space savings and reliability are factors. It features a single-pole single-throw normally open (SPST-NO) contact configuration, appropriate for application to circuits in which simple on/off control triggered by linear motion is needed.

The module is actuated by a plunger-type actuator, which responds to direct mechanical pressure with an operating force rated at 100 grams-force (gf), offering sensitive switching action with moderate mechanical effort. It has a silver alloy contact material chosen for conductivity and wear life to offer consistent electrical performance throughout the module's life. The unit is designed to withstand up to 1,000 V AC dielectric voltages for one minute to allow it to insulate electrical signals safely and retain internal integrity with exposure to high voltage. The HCMCO1-A offers a minimum electrical life of 30,000 operations, allowing support for repeated use in repetitive switching operations without loss of contact reliability. The terminal type is wire lead, allowing easy and flexible connection to control circuits, especially in compact layouts or installations where plug-in terminals are not feasible. With an IP40 protection rating, the module offers basic protection against solid objects greater than 1 mm but is designed for indoor use in environments without exposure to dust or moisture. Its design allows it to be used where control panels, mechanical interlocks, and equipment are space-efficient and require precise actuation. Compact and light, yet functionally reliable, the HCMCO1-A offers mechanical sensitivity with electrical durability.

It is especially well suited for application in switches requiring responsive switching in low-force conditions, especially where high contact integrity and consistent performance over many actuation cycles are also required. The HCMCO1-A is an easy solution for customers who need a plunger-actuated, silver contact switch module for space-efficient control or automation use.
