Proximity Switches
A variety of packages are available to suit the switch mounting method. Switches are offered in the form which is easiest for the customer to use.
We fabricate proximity switches with high contact reliability using high-reliability, high-quality reed switches based on our unique contact surface deactivation treatment technology. These reed switches have the top market share in Japan. We use our own reed switches, so we can realize precise operating characteristics and functions

Shock Sensors
Shock sensors must have extremely high-precision operating conditions and characteristics. We speedily provide custom products to suit customer specifications.
Through our technical alliance with Hamlin Electronics (USA) we have commercialized an electric safety sensor used in automotive air bag systems. RRPC Series products are comprised of a reed switch, magnet and spring. During acceleration detection, the magnet moves and the reed switch actuates. This actuation is adjusted to meet
specifications suited to the characteristics of each vehicle determined computer simulation, so products can be supplied with a short lead time.
