Trusted by over 20 major machinery manufacturers, our products are CE, UL/cUL, and RoHS compliant, with a proven export record to North America and Europe. Clients highly value our ability to provide "full regulatory compliance at a reasonable price."
Our non-contact safety switches feature superior durability, excellent dust and water resistance, easy installation, coded magnets for tamper protection, and a built-in anomaly detection circuit.
We are actively seeking distributors worldwide to bring these proven, high-quality safety solutions to new markets.
SS2 and SS3 series (plastic type)
Non-contact safety door switches SS2 and SS3 (plastic type)
- High Reliability
The internal architecture is designed to ensure safety even in the unlikely event of an emergency.
- High Durability
Non-contact safety door switches are free from the mechanical wear or failure that occurs with mechanical switches.
- Excellent Dust and Waterproof Performance
We achieved an IP68 rating by sealing the housing. Suitable for use in harsh environments.
- Stand-Alone Application
The built-in anomaly detection circuit for the SS2 series reduces costs by eliminating the need for a relay unit.
- Easy Mounting and Adjustment
The non-contact system makes it easier to mount the switch and adjust the positioning.
- Invalidation Prevention
Coding is achieved by using multiple magnets, which prevents the invalidation of safety functions.
SS2 and SS3 series (stainless type)
Non-contact safety door switches SS2 and SS3 (stainless type)
- Laser-Marked Housing:
The surface of the stainless steel housing is laser printed, preventing contamination by foreign materials from the safety switch itself.
- Excellent Dust and Waterproof Performance
We achieved an IP69K rating for the stainless type by sealing the housings, making it suitable for use in harsh environments.
We offer a diverse lineup featuring various Performance Levels (PL), sizes, and output methods to suit your specific needs.

Ensuring Precise Positioning in Semiconductor Material Handling
Use Case 1: Semiconductor material handling system
The SS2 series features anti-bypass coding, a built-in protective fuse, and fault detection to help maintain safety compliance.
Protecting Operators by Preventing Unsafe Machine Operation
Use Case 2: Food-processing equipment doors
Safety interlock switches detect guard status so the machine immediately stops when the guard is open and runs only when it is closed.
The SS2 series adds anti-bypass coding, a built-in protective fuse, and fault detection to help ensure reliable protection.
